Standard financial advice says: always sell RSUs and diversify. But if you sold your Nvidia RSUs in 2022 to diversify, you missed a 10x run. Here's a nuanced framework that goes beyond the standard advice.
What Are RSUs and Why Do They Create Concentration Risk?
An RSU (Restricted Stock Unit) is a form of equity compensation where your employer grants you a certain number of shares that vest over a schedule — typically 4 years at 25% per year. At the vesting date, the shares become yours and are treated as ordinary income: you owe income tax on the full market value of the shares that day, whether you sell them or not.
After vesting, you hold the shares exactly like any stock you bought yourself. Your cost basis is set at the market price on the vest date, which matters for calculating future capital gains.
The concentration risk: If you work at a tech company where 60–70% of your total compensation is paid in equity, you can easily end up with 30–50% of your net worth in a single company's stock. Worse, your income and your savings are both tied to that same company — if the company struggles, you could face layoffs and a portfolio collapse simultaneously.
Both scenarios represent the same total net worth. The difference is that Scenario A ties the vast majority of that wealth to a single outcome — your employer's stock performance.
The Case FOR Selling RSUs (The Standard Advice Is Mostly Right)
Financial advisors almost universally recommend selling most RSUs at or near vest. The reasoning is sound:
Double exposure: You already depend on your employer for your paycheck. If the company struggles, you could lose your job AND watch your portfolio collapse simultaneously — exactly what happened to Enron employees in 2001.
Concentration amplifies losses: A 50% stock drop hurts twice as much when that stock is 50% of your portfolio versus 10% of it.
You're not being compensated for concentration risk: Unlike a founder who took real risk building the company, you're an employee compensated at market rate. You don't need to take on additional concentration risk to earn your pay.
The 10–15% rule: Most certified financial planners recommend that no single stock should exceed 10–15% of your total net worth.
Historical Warning
In the 2001 dot-com crash, thousands of employees at Lucent, WorldCom, and Nortel held concentrated positions in their employer's stock. Many lost both their jobs and 80–90% of their savings simultaneously — a double catastrophe that proper diversification would have prevented.
The Case AGAINST Always Selling (The Nuance)
The counterargument is real and powerful — especially if you work at an exceptional company:
You have an information edge: You know more about your company's competitive position, culture, and trajectory than any outside investor. If you genuinely believe in the business, your conviction is well-founded.
Selling at vest triggers no extra tax: RSUs are already taxed as ordinary income at vesting regardless of whether you sell. Selling immediately adds only a minimal additional taxable event.
The Nvidia example: NVDA employees who sold all RSUs in 2021–2022 during the selloff and diversified into the S&P 500 would have seen roughly 10% annual returns. Nvidia returned approximately 900% over the same period. Missing a 10x on a meaningful position is a devastating financial setback.
Quality matters: Diversifying out of NVDA, MSFT, or AAPL into the S&P 500 may actually reduce portfolio quality — these businesses are genuinely exceptional.
Company
If You Sold RSUs in...
Result vs Holding
Nvidia (NVDA)
2022 dip
Missed ~900% gain
Microsoft (MSFT)
2016
Missed ~10x run
Amazon (AMZN)
2015
Missed massive gains
GE
2000 (or later)
Selling was the right call — stock fell 90%+
Enron
2000 (or earlier)
Selling was critical — company went to $0
Cisco (CSCO)
2000 peak
Selling was right — still below 2000 highs 25 years later
Key insight: The outcome depends almost entirely on company quality. Diversifying from exceptional, growing businesses often costs you dearly. But holding concentrated positions in declining companies is catastrophic. The decision is really a question about business quality — not a blanket rule about RSUs.
A Framework — How Much to Keep vs Sell
The goal is to retain meaningful upside in great companies while eliminating the risk of catastrophic outcomes.
The Concentration Rule
Never let a single stock exceed 20% of total net worth (use 10% if you are more risk-averse). Sell enough RSUs on each vest date to stay within this limit, regardless of how bullish you feel.
The Quality Test: 5 Questions Before Keeping RSUs
Before deciding to hold shares above your minimum diversification level, answer these honestly:
Is the company's competitive position improving or declining over the past 2 years?
Is revenue growing faster than 10% per year?
Does it have strong pricing power? (gross margins above 50% for software/tech)
Would you buy this stock at its current price if you did NOT work there?
Is the CEO and management team trustworthy and long-term oriented?
4–5 Yes
Keep up to 15–20% of net worth
3 Yes
Keep up to 10% of net worth
0–2 Yes
Diversify aggressively on each vest
The 3-Bucket Approach
Bucket 1 — Sell at Vest
Enough to cover your tax bill + enough to bring the stock below your max concentration limit. Non-negotiable.
Bucket 2 — Hold with Plan
Shares you actively believe in. Set a predetermined exit trigger: 'I'll sell if this hits X% of net worth' or 'if my investment thesis changes.'
Bucket 3 — Long-Term Hold
If you have shares in a tax-advantaged vehicle (rare for RSUs, more common for ESPP), let these compound with minimal trading.
Tax Strategy for RSU Sales
RSU taxation is unavoidably complex. Here is the essential framework:
At vest: you owe ordinary income tax on the full market value of vested shares — this happens whether you sell or not. Your employer withholds taxes just like a paycheck.
Your cost basis is set at the market price on the vest date. This is critical for calculating future capital gains.
Sell immediately at vest: likely a near-zero capital gain or small short-term gain (minimal additional tax beyond what you already owe at vest).
Hold more than 1 year after vest, then sell: long-term capital gains rates apply (0%, 15%, or 20% depending on your income) on any appreciation above vest price.
Hold less than 1 year after vest, then sell: short-term capital gains (ordinary income rates) apply on appreciation.
Key Tax Insight
Selling RSUs immediately at vest has minimal additional tax impact — you already owe income tax on the vest value regardless. The main tax decision is about when to sell shares you decide to hold after vesting. Waiting at least one year after vest converts any gains from ordinary income rates to long-term capital gains rates (typically 15–20%), which can be a significant tax savings if the stock appreciates.
Special Cases
High-Growth RSU Holders (Nvidia, Tesla, etc.)
If your employer has been a 20%+ per year compounder, keeping 15–20% of net worth is a reasonable and defensible position. The mistake is holding 60–80% — that is not investing, it is concentrating your entire financial future on a single outcome. Consider "trimming into strength": sell partial positions as the stock rises and your concentration increases, locking in gains while maintaining meaningful exposure.
New Grad at a Big Tech Company
Your net worth is small and RSUs may dominate your total assets. Be patient — sell enough on each vest to fund a diversified portfolio. As your savings grow, the percentage tied to employer stock naturally dilutes. Avoid letting early bull runs convince you to forgo diversification.
Employee at a Declining Company
Sell immediately on vest, full stop. Your employment at the company is already substantial exposure to that single outcome. There is no rational reason to add financial exposure on top of career exposure when the business is deteriorating.
Pre-IPO RSUs
Pre-IPO shares are illiquid and may have extended lockup periods after an IPO. Be very conservative in your financial planning — treat pre-IPO RSU value as $0 until shares are actually liquid and you have verified the price. Many employees at companies that IPO'd in 2021 saw their paper wealth evaporate within 12 months.
The Actionable Rule Set
Six rules to guide every RSU decision:
1
Sell enough RSUs at vest to cover your tax bill
Your broker will withhold some, but verify — underpaying estimated taxes has penalties.
2
Never let employer stock exceed 20% of total net worth
Conservative investors should use a 10% cap. Enforce this by selling on each vest if needed.
3
After 12 months post-vest, ask: would I buy this at today's price?
If the honest answer is no, sell. Inertia is not a strategy.
4
Hold a maximum of 15–20% if the company passes your quality test
Only if 4+ of the 5 quality questions answered yes. Otherwise cap at 10%.
5
Set a predetermined exit trigger before you vest
Decide in advance: 'I will sell if concentration hits X%, or if Y happens.' This removes emotion from future decisions.
6
Never factor in sentimental attachment to your employer's stock
Loyalty to your employer is admirable. Loyalty to their stock at the expense of your financial security is not.
