  • When Should You Sell a Concentrated Stock Position?

    Let me know if this sounds familiar. You’ve watched a position grow from a small bet into a significant chunk of your net worth. Now you’re not sure what to do.

    You might leave a fortune on the table if you sell.

    But you might lose everything you’ve built if you keep holding. 

    This is one of the most common scenarios I discuss with people. Stock that’s built up through RSUs, an early position in Bitcoin, or a bet made on a Mag 7 years back. This position now accounts for a significant portion of this person’s wealth and they’re not sure what to do next.

    Here’s how I talk people through this situation. 

    Before thinking about any further upside scenarios, think about the downside. 

    What would happen if this position went to zero?

    Are your financial goals dependent on this position not going to zero? If yes, that’s a sign your concentration risk is real, not theoretical. 

    Here are three scenarios when you should consider selling down some of your position. We’ll ignore tax implications for now in each of these to keep the examples simple.

    You’ve Won the Game

    If this position is worth so much that you could comfortably live off the proceeds for the rest of your life, you’ve already won the game. You don’t need to go for the highest score possible.

    How much is enough to live off?

    The 4% rule is imperfect but a reasonable starting benchmark.

    Let’s say you have $10m in vested RSUs which make up the bulk of your net worth. Your current living expenses are $300k a year (3% of your assets). 

    Congratulations, you are financially independent.

    You could sell out $7.5m of your vested RSUs and diversify it to lock your future in ($300k a year in spending needs divided by 4%). Then keep your other $2.5m invested if you still believe in the company’s future.

    You take your winnings off the table while keeping your upside open.

    Your Financial Plan Now Depends on This Position

    Even if you haven’t reached the point where your assets can fully support your lifestyle, your position may have accelerated your timeline by decades. 

    Let’s say you’re 40 and you have $6m in a crypto asset thanks to your foresight to invest a decade ago. 

    You have another $1m in traditional retirement accounts. You put away an additional $200k a year from your job and your goal is to get to $8m total net worth before you retire from the corporate world. 

    If you diversify out of your crypto position today into a more conservative mix of assets returning 7% a year, you will reach your goal after ~1.5 more years of work.

    Sure, your crypto position could catapult up in the next two months and help you reach your goal faster. But what if it goes to zero? Your timeline to retirement just extended by decades.

    There is an asymmetric risk here in continuing to stay so heavily concentrated.

    Your Life Directly Benefits From Selling

    It’s important to think about the present value of your life, not just the future value of your assets.

    The tradeoffs you’re evaluating are not always about pure financial optimization. 

    For example, you and your spouse might be expecting your first child together later this year and would like to move into your dream home to build lifetime family memories. 

    You’ve been steadily saving cash for a down payment but that still need another three years to get to the number. Meanwhile, you have your down payment sitting right there in vested options that you could exercise today and make your dream life a reality three years earlier. 

    Sure, those options could be worth hundreds of thousands more years from now if you keep holding until expiration. 

    But is that what you want? An extra two hundred thousand ten years from now when it won’t make much of a difference in exchange for three years of lost family memories while you’re in the prime of your life?

    The right answer to a concentrated position isn’t always the one that maximizes expected value. Sometimes it’s the one that makes the life you actually want to live possible three years earlier. 

    I wrote about this in more detail in this piece.

    What About Taxes?

    The tax implications of selling a concentrated position are significant and worth their own deep dive. Especially for ISOs, RSUs, and crypto where the treatment differs meaningfully. 

    I’ll write more about minimizing taxes when selling out of a concentrated position in a future piece. Subscribe to follow along.

  • Why I Paid Cash for a House When Every Spreadsheet Said Not To

    Most financial advice assumes people are machines making objectively optimized decisions.

    They aren’t. The best financial decisions I’ve ever made looked suboptimal on a spreadsheet. 

    When our company got acquired back in 2017, I ended up with significant assets for the first time.

    I decided to use some of that money to buy a modest house in Beacon, NY. I bought it outright. No mortgage.

    Any simple financial analysis would have said paying all cash for property was leaving money on the table. Buying the home with a mortgage would have allowed me to keep the difference invested in the markets. This could have resulted in tens of thousands more in net worth over the course of decades. 

    I was fully aware of the financial tradeoffs. 

    But what I wanted psychologically and emotionally from the purchase outweighed what the spreadsheets said.

    I had been living in NYC in tiny apartments for more than a decade at this point. I wanted to evolve my lifestyle. I wanted space and the ability to access nature by train whenever I felt like it.

    I had also been renting my entire adult life until this point. I wanted a portion of my assets locked into something that was mine no matter what happened to my job or to the markets. 

    Sheila had also just moved in with me and I wanted to start building a life with her. 

    Spending the next few years going up to Beacon gave us both experiences we’ll look back on fondly for the rest of our lives. It was exactly what we both needed at the time. 

    The price of something is not synonymous with its value. I think I underpaid for that home.

    A man and woman posing for a selfie at a scenic overlook, with a lush green landscape and river in the background.
    First hike up Mt. Beacon in 2018. Worth every dollar the spreadsheet said I was leaving on the table.

    Nearly every client who comes to me with a major decision is navigating both the financial and emotional tradeoffs of the options they’re facing. Here’s a recent example. 

    I’m working with a family saving up for their ultimate dream home.

    The cash they were able to put away each month meant saving up for that down payment could have taken seven or more years. That’s seven years of forgone memories and experiences. 

    One of them works for a Fortune 500 and had sizable amount of vested company stock options. The expiration date was still years in the future. The company’s stock had rocketed up in the past year and a huge chunk of their down-payment could be realized if they exercised their options. 

    Conventional financial models suggested continuing to hold the options would maximize their net worth ten years from now. We talked it through and modeled the potential tradeoffs and it was a no-brainer.

    The certainty of locking in their down payment and bringing their dream up by five years was worth more than any theoretical money left on the table. Five additional years of a dream life they could be living now vs. a higher net worth decades in the future that would have only a marginal impact on their future selves.

    Five years of living in their dream home is not a line item on a spreadsheet. Neither were the years Sheila and I spent going up to Beacon. The point was never financial optimization.

  • 42% of Heirs Spend Their Entire Inheritance Within the First Year

    That’s according to recent research.

    I don’t see that number as just a financial statistic. It’s clearly a design problem.

    We have two young kids. I think a lot about how we should structure our trust to ensure their futures are protected. Not just from probate and unscrupulous advisors. But also from themselves.

    I think back to when I was 18 or 25. Would I have had the self control or even financial knowledge then to handle a sudden inheritance? Absolutely not.

    It’s not just age though.

    The worst time to transfer assets is upon death. Emotions are high. There may be negative associations with the sudden windfall. The urge to spend it to relieve those feelings is real.

    What I’m personally including in our trust is what the researchers recommend.

    Phased distributions. They’ll get their full inheritance, just not all at once.

    The goal isn’t to protect the money from them. It’s to protect them from receiving it before they’re ready. There’s a difference.

  • The Identity Shift That Comes With Leaving a C-Level Career

    The hardest part of leaving a C-level career wasn’t losing the salary. Income from my portfolio had already replaced that. It was the morning I realized I didn’t know how to introduce myself anymore.

    I’d spent nearly two decades building skills, reputation, and relationships in the marketing world. Almost my entire network knew me from that perspective. Even my wife has only known the “senior corporate guy” version of my professional life.

    Here’s what that first year actually looks like, both from living it and from sitting across from people navigating it now.

    The phone rings a lot less. The steady white noise of a million Slack notifications disappears (this part wasn’t so bad).

    You’ll spend real time wondering if you made a mistake. Not occasionally. Regularly.

    You’ll pivot your idea for the second act more times than you expected. The boutique consultancy becomes something else. The advisory practice gets repositioned. Each pivot feels like failure until it doesn’t.

    And then, without being able to pinpoint exactly when, you stop identifying with the old title entirely. Someone asks what you do and the corporate version doesn’t even come to mind.

    Nobody warned me the identity piece would be the hardest part of financial independence.

  • I Left My C-Level Job at 38 to Build the Advisory Firm I Couldn’t Find

    When I left my C-level job in 2024, I didn’t have a business plan. I had a conviction.

    I was 38. Income from my investment portfolio had already replaced my salary. I’d spent years building something most financial advisors told me wasn’t realistic. A life funded by cashflows from investments, not a passive index fund I’d spend down at 65.

    All along the way I had been looking for an advisor who understood what I was building. Someone who could help me go further. Private markets, real estate, infrastructure. The way large endowments invest to fund their mission in perpetuity, but for individual investors.

    I couldn’t find one.

    Every advisor was oriented around a 60/40 portfolio and a retirement at 65.

    So I decided to build what I had been looking for. Something for people like me.

    I now work with people who want to replace a paycheck with income from their portfolio. Not someday, on an arbitrary retirement timeline, but intentionally and as soon as their portfolio makes it possible.

    What I love about what I’m doing now: I sit down with people and show them how to cut years off the timeline they had in their head through the same style of investing and financial planning that made it a reality for me.

    If you’ve had similar experiences with financial advisors trying to stick you into cookie-cutter formulas, I’d genuinely like to hear about it.

  • When Should I Exercise My Options?

    The optimal time to exercise your options and the right time to exercise your options are often different things. Here was the deciding factor for a director at a F500 company.

    Using Options to Realize Your Dreams

    The situation:

    • Mid 30s couple with two young children
    • Approaching mid-six figure income but majority of net worth locked in unexercised company options
    • Owns their current home

    The dream:
    Upgrade to a seven-figure forever home at some vague point in the future, but unsure when or if they could afford to do it.

    The strategy:
    Shifted timeline from vague future to 18 months by realigning financial focus on making this a reality:

    • Accounting for current home equity value
    • Creating targeted savings augmentation strategy using higher, after-tax yielding instruments than a typical HYSA
    • Exercising a portion of their options

    The “objective” answer to the optimal time to exercise options involves lots of academic calculations and hyper-specific, unknowable assumptions.

    The practical answer?

    Sometimes it’s as simple as looking at whether exercising your options allows you to live the life that you want to live now.

    I built a custom model for this client to determine how much we should exercise now vs. how much we should leave on the table to preserve future upside. We then exercised our target portion and locked in nearly six figures of their down payment – putting them solidly, and definitively on track to their dream home by this time next year.

    What Other Situations Does it Make Sense to Exercise Options Early?

    There many other situations where exercising your options earlier may make more sense than holding them including:

    • When you’re switching jobs and the options expire when your employment does
    • When you need immediate cashflow for a major life event
    • When you feel your net worth may be too concentrated in the position and you want to diversify your risk

    Financial tools should serve the life you’re designing, not the other way around. The academic optimal is often the enemy of the intentional.

  • Can I Afford Private School?

    I speak with a lot of high-earners who feel financially squeezed by private school. This is what we talk about together.

    When high earners have vague feelings of financial uncertainty, it’s not usually an issue of whether a specific item is affordable today.

    It’s more a question of long-term financial clarity. What implicit or explicit sacrifices are you making down the line because of how you want to support your family today?

    Paying for private school is one of the most common versions of this conversation. Three kids, $30K per year each.

    Although it technically fits in the yearly budget, there’s a creeping fear that paying tuition now is quietly stealing from retirement later.

    For the people in this situation, people who started saving aggressively in their late 20s and early 30s, that fear can be exaggerated.

    When you actually model it out, the nest egg they’ve already built is doing more work than they think.

    Here’s a quick hypothetical example.

    • A couple, both around 40 in a high-cost-of-living area
    • They earn $500k but feel squeezed between taxes, mortgage, and daily expenses
    • $2M already saved across retirement and investment accounts
    • They have three kids they want to put through K-12 private school that costs $30k per year per child

    Even if this couple stopped contributing to retirement for the next 25 years, that $2M they have now could grow to more than $12M by retirement at 65 assuming historical market returns on a moderately aggressive allocation between now and then.

    $12M in assets could equate to $480,000 in annual retirement spending using the simplified 4% rule.

    The wealth management industry has done an excellent job scaring high earners into maximizing retirement contributions at all costs. Some of that fear is legitimate. But for people who started early and saved aggressively, the marginal retirement contribution can end up being a nice-to-have, not a necessity.

    One of the most valuable things I do for clients is helping them see that they already have more financial flexibility than they’re giving themselves credit for.

    The clarity that comes from understanding short, medium, and long-term tradeoffs changes how people make decisions. It changes how they think about their careers. It changes whether they take the sabbatical, fund the private school, or finally make the move they’ve been deferring.

    The numbers are usually better than the fear.

  • Permission to Spend

    I’ve realized over the past year I don’t think about portfolios the way most people do. 

    I view portfolios as infrastructure that enables life to be lived intentionally. 

    I think a lot about what the point of investing is. And I spend a lot of time talking to people about what they want their portfolios to make possible for them. The most important framing has nothing to do with investing. It’s: 

    What is the life I want to live? 

    When I was in my 20s, I thought what I wanted was to end the game with the largest number possible.

    But over the years I’ve realized the point isn’t to die with the largest portfolio but to live a life that I can reflect back on and feel was truly enjoyable along the way. 

    A Personal Endowment is the best metaphor for what I’m trying to build. I want a portfolio that pays a steadily increasing income year over year that supports the life our family wants to live. 

    I am a product of two first-generation immigrants. Frugality and intentional spending were highly valued in our household. It is hard for me to “enjoy” spending money. I get much more of a thrill out of finding a good deal than in paying for an unnecessary luxury.

    This mindset helped me “retire” from a C-level career before 40. But it also meant years of depriving myself of vacations, concerts, and other experiences that I’ve come to regret.

    The forced cashflow that comes from the diversified income portfolio we live off has been a strong mechanism for enjoying life more with each year. It’s a number that is meant to be spent in order to ensure I don’t look back on missed experiences or the opportunities to treat the people I love.

    It’s become a system specifically designed to prevent my frugality and accumulation instinct from consuming the enjoyment that financial independence was supposed to enable. 

    What is it like living off income from a portfolio?

    Here’s what this looks like in our actual day to day life.

    I start each year by projecting out the cashflows our portfolios are expected to generate which forms our yearly budget. 

    As the year progresses, those cashflows have steadily increased (so far). 

    By September, I start paying out a portion of that excess cashflow to ourselves as a monthly bonus.

    During the holidays we’ll take some more of that excess cashflow and donate to causes we care about and then treat ourselves to a nice gift. Something we wouldn’t normally buy ourselves but we know we’d enjoy. This past year it was a new Switch for me and a nice pair of earrings for Sheila.

    When the new year starts, the budgets ratchet up as the cashflows increase. As the budgets increase, I try to make sure we’re intentionally setting aside funds to enjoy life together. 

    This year it was an extra $7,000 for vacations which we spent going to Sarasota in the winter months.

    My parents optimized for security. I spent years optimizing for financial independence. Now the forced cashflow from my income portfolio is optimizing for something neither of us quite had: the permission to actually enjoy what we built. 

    The financial independence I was building would solve life’s money problem. But the psychology that got me there would have prevented me from actually living it.

  • Why is it important to benchmark your portfolio?

    Here’s how 1.0% turns into a $29,000 blind spot

    This is part of a series deconstructing a Portfolio Efficiency Audit we recently completed for a new client. For a $2.9M portfolio, these combined deficiencies can represent an annual opportunity cost in the low-to-mid five figures. We consistently see these issues across clients who have managed their own portfolios and those who have switched to us from other advisors.

    The Problem:
    Everyone has seen the headlines that active portfolio managers can’t beat a passive index. But most clients we work with have never seen their portfolio’s performance lined up against these passive benchmarks before coming to us. Especially those working with other advisors (three guesses why an advisor might like to obscure this data).

    The Math:
    Here’s some illustrative numbers to show how a $2.9M portfolio underperforming benchmarks isn’t just a rounding error:

    • at 0.5% it’s $14,500 a year in lost opportunity
    • at 1.0% it’s $29,000 a year
    • at 1.5% it’s $43,500 a year

    At 1.0% a year you’re looking at $290,000 over the next ten years – before taking into account any growth.

    The Strategy:
    The first step of our audit is a cold, hard look at reality. We benchmark our clients’ legacy portfolios against objective global benchmarks to identify where there may be major performance gaps.

    S&P recently found 88.3% of active managers underperformed the S&P 500 over the last 15 years. In large-cap stocks, the “market return” is often the smartest move.

    Conversely, that same study found 40.7% of US Muni Managers beat their index in that timeframe. This is where careful selection of active managers may pay off.

    We look at the portfolio as a whole and individual asset classes.

    An effective portfolio manager knows where to accept the indexed market return and where active management actually adds value.

  • Paying for K-12 Tuition with a 529

    In many states you can use 529 funds for K-12 private school tuition. And by routing payments through a 529 first you can capture a state tax deduction on spending you were going to do anyway.

    I’ve noticed so many parents paying private school tuition are leaving free money on the table every year. And it’s all because of a simple sequencing mistake.

    Here’s what I mean.

    Let’s say you live in Pennsylvania and have two kids in K-12 private school. Tuition is $30,000 per year per kid.

    You’re probably writing a check directly from your bank account. Straightforward. Simple. And quietly costing you $1,228 per year in state tax savings you didn’t have to give up.

    Here’s a better approach.

    The federal limit for using 529 funds for K-12 expenses was bumped up to $20,000 per student per year as of 2026.

    So instead of paying tuition directly, first deposit the funds into each child’s 529 Plan. Then pay the tuition from the 529. That’s it.

    PA allows you to deduct 529 contributions from your state taxes, and because there’s no minimum holding period before using the funds for qualified K-12 expenses, you’ve effectively turned a routine tuition payment into a state tax deduction.

    Here’s the simple math.

    • $20,000 per child (the federal limit) × 3.07% PA state tax rate = $614 back per child
    • Two kids = $1,228 per year. Every year. For spending you were going to do anyway.

    Not life-changing money. But $1,228 in annual savings that compounds over a decade of private school tuition is worth knowing about — especially when capturing it only takes a few steps.

    Note, every state has different rules. Some don’t allow K-12 deductions at all. Some have contribution limits that affect the math. Check your state’s specific rules or ask an advisor. If you’re a high earner in a high-tax state, your numbers could look even better than the Pennsylvania example above. The higher your marginal state rate the more this matters.

    This is one of those optimizations that looks small in isolation but is exactly the kind of thing that adds up when you’re navigating the squeeze years — private school, mortgage, family life, and trying not to compromise what you’re building for the future.

    If you’re navigating the squeeze years I’d be curious what financial questions are keeping you up at night.
