Your restricted stock units just vested. Should you hold them or sell? Here's what the research says — and why the answer is simpler than you think.
The Core Question: Would You Buy This Stock?
RSUs are taxed identically to a cash bonus at vesting. So the real question isn't whether to sell — it's whether you'd buy.
The most common RSU structure in 2026 is a 4-year vest with a 1-year cliff. On a $400,000 grant, that's $100,000 vesting at the one-year mark — one decision — followed by $25,000 every quarter for three more years, totaling 12 more decisions. That's 13 separate decision points between grant and final vest.
Here's the reframe that changes everything: imagine you received $100,000 in cash on your one-year anniversary. Would you immediately use that cash to buy $100,000 of your employer's stock? If the answer is no, then holding your vested RSUs is making that same bet — actively, every quarter, for three more years. The only difference is that holding feels passive. Financially, it isn't.
The Research: The Odds Are Not in Your Favor
Decades of data tell the same story: concentrated single-stock positions are a losing bet for most investors.
66% of individual stocks underperformed the Russell 3000 index over their lifetimes, and 42% delivered a negative absolute return, according to J.P. Morgan Asset Management's analysis of all Russell 3000 constituents from 1980 to 2020 (The Agony & the Ecstasy, J.P. Morgan). And since the end of World War II, the median ten-year return for recent top-performing stocks has trailed the broad market in 93% of measured periods (Petajisto, NYU Stern, 2023).
The odds bar says it plainly: two out of every three individual stocks underperformed a simple index fund. The data isn't ambiguous, and your employer's stock is not an exception until it has proven otherwise.
The Hidden Risk: The Double Concentration Problem
Most employees don't just hold company stock — their income depends on the same company. That's two bets on the same outcome.
Your RSUs, ESPP shares, and vested equity are all tied to one stock — that's your investment risk. Your salary, bonus, and future grants are also tied to the same company's continued success — that's your income risk. When a company stumbles, both are affected simultaneously. A 40% stock drop doesn't just shrink your portfolio. If that drop coincides with layoffs, a hiring freeze, or cancelled bonus cycles — your paycheck and future equity are in the same trouble at the same time.
This is the double concentration problem, and it's the most underappreciated risk in equity compensation planning.
Examples of Over Concentration Hurting Employees
Real Employees with Real Consequences
Employees at these companies held concentrated stock positions and lost retirement savings and paychecks at the same time.
Enron, December 2001. Employees held 62% of their 401(k) assets in Enron stock. When the company filed for bankruptcy, employees lost more than $1 billion in retirement savings from their 401(k) plans, and thousands lost their jobs (Senate Committee on Governmental Affairs, 2002). The stock fell 99%.
Lehman Brothers, September 2008. Employees held significant portions of their savings and retirement funds in Lehman stock, which became worthless overnight. The firm collapsed in what was then the largest bankruptcy in U.S. history, leaving approximately 25,000 employees without jobs (Harvard Baker Library). The stock fell 100%.
Silicon Valley Bank, March 2023. The bank collapsed in 48 hours. Employees with stock-heavy compensation packages saw their equity wiped out. Many faced job uncertainty as the bank was seized and later sold to First Citizens Bank. The stock fell 100%.
The pattern is structural, not coincidental. In each case, the investment loss and the income loss came from the same source at the same time.
Diversification after RSUs Vest
Selling RSUs at vest and diversifying doesn't mean leaving the market — it means spreading the risk across it instead of concentrating it in one place.
What the Fix Looks Like
Selling RSUs at vest and diversifying doesn't mean leaving the market — it means spreading the risk.

Are You the Exception?
There are legitimate reasons to hold RSUs after vesting. But the bar is higher than most employees realize.
Are You the Exception?
True Company Insider (Very Rare — Executives Only). C-suite or senior leadership with genuine strategic visibility may have a case for holding — but this group is far narrower than most employees realize. True insiders are subject to blackout periods, 10b5-1 plan requirements, and strict SEC rules on trading. Trading on material non-public information isn't a gray area — it's a federal crime. Even genuine insiders are vulnerable to enthusiasm bias, and operational knowledge is not the same as strategic knowledge. AOL-Time Warner employees watched their individual business units succeed while the combined company destroyed an estimated $200 billion in shareholder value.
Pre-IPO or Early-Stage Growth (Rare — Timing-Dependent). If your RSUs represent meaningful ownership in a company not yet fully valued by the market, holding may make sense. Nvidia has returned thousands of times its IPO price — but it's the rare exception, not the rule. Walgreens has shed more than 80% of its value since 2015.
Tax Optimization on Seasoned Shares (Conditional — Tax Planning). Previously vested shares with significant appreciation may qualify for long-term capital gains rates if held 12+ months. This is a tax planning strategy, not a reason to never sell.
RSUs Are a Tiny Slice of Your Wealth (Very Rare — High Net Worth). If $500,000 in employer stock represents 3% of a $15 million diversified portfolio, concentration risk is negligible. This only applies when the rest of the portfolio is genuinely diversified.
Mandatory Holding Requirements (Very Rare — Corporate Policy). Some executives are required to maintain minimum stock ownership levels by corporate policy, or are subject to blackout periods that restrict when they can trade.
For most employees receiving RSU grants, none of these apply. Holding RSUs without a clear, deliberate reason means accepting uncompensated concentration risk while your paycheck already depends on the same company.
Frequently Asked Questions
Should I sell my RSUs as soon as they vest?
For most employees, yes. RSUs are taxed as ordinary income at vesting regardless of whether you sell — so holding them is a deliberate choice to own your employer’s stock, not a default. If you wouldn’t buy that stock with a cash bonus, holding is making the same bet.
What’s the tax treatment of RSUs at vesting?
The fair market value of your RSUs on the vest date is treated as ordinary income and subject to federal, state, and payroll taxes — the same as a cash bonus. Any subsequent gain or loss after vesting is treated as a capital gain or loss depending on how long you hold the shares.
What is the double concentration problem?
Having two significant financial exposures tied to the same employer: your investment portfolio (RSUs, ESPP shares, vested equity) and your income (salary, bonus, future grants). If the company struggles, both can be affected simultaneously.
Are there legitimate reasons to hold RSUs after vesting?
Yes, but the bar is higher than most employees realize. The clearest cases are: C-suite insiders with genuine strategic visibility (subject to strict SEC rules and 10b5-1 requirements), pre-IPO equity not yet fully valued by the market, holding seasoned shares 12+ months for long-term capital gains treatment, RSUs that represent a negligible slice of a much larger diversified portfolio, and mandatory corporate holding requirements.
What does diversifying RSUs actually look like?
Selling vested RSUs and reinvesting the proceeds into a diversified portfolio — broad index funds, bonds, international equities, real estate. It doesn’t mean leaving the market. It means spreading risk across many companies instead of concentrating it in one.
Can I hold RSUs for long-term capital gains treatment?
Yes. If you hold shares for more than 12 months after vesting, any appreciation above the vest-date value qualifies for long-term capital gains rates. This is a legitimate tax planning strategy — but it’s a reason to be thoughtful about timing, not a reason to hold indefinitely or ignore concentration risk.
What should I do if I’m subject to a blackout period?
Blackout periods restrict when you can trade, not whether you can plan. Work with a financial advisor and your company’s legal counsel to set up a 10b5-1 plan, which allows you to schedule sales in advance during open trading windows.
How do I think about RSUs as part of my overall financial plan?
Start by calculating what percentage of your total net worth is tied to your employer — including RSUs, ESPP, unvested grants, salary, and bonus. If that number is above 10–15%, you likely have meaningful concentration risk worth addressing.
