Should I Sell My Company Stock, RSUs or ESPP Shares?

Short answer

The core issue with employer stock is double exposure: your salary and your savings both depend on the same company, so a bad year for the business can hit your income and your portfolio at the same time. The useful test is the fresh-money test. If your vested shares were paid as cash instead, would you use that cash to buy this much of your employer’s stock? If the answer is no, holding is an active decision to keep a concentration you would not choose. Taxes, blackout windows and vesting schedules shape how and when to act, but they do not change the underlying question.

Company stock accumulates quietly. RSUs vest every quarter, an employee purchase plan buys at a discount, and a few years later one position is a large share of everything you own. It rarely feels risky, because you know the company, you believe in it, and selling can feel disloyal. This page does not tell you whether to sell. It explains why concentration in your employer is a different kind of risk from any other holding, the test that removes loyalty and familiarity from the decision, and how to measure what holding has actually done to your portfolio.

Double exposure is the real risk

Most concentrated positions only put your savings at risk. Employer stock also puts your income at risk, and the two tend to fail together: the conditions that push the share price down are often the same ones that lead to hiring freezes, reduced bonuses or layoffs. That correlation is why a position that would look like a moderate bet in someone else’s portfolio is a bigger one in yours.

The fresh-money test

When RSUs vest, they are taxed as income as if you had received cash and used it to buy shares. So ask the question directly: if this value arrived as cash today, would you buy this much of your employer’s stock with it? If yes, holding is consistent with what you would choose. If no, keeping the shares is the same as making that purchase every time they vest. The test removes the feeling that selling is a separate, bigger act than holding.

Familiarity is not information

Working somewhere gives you a detailed view of the company, which feels like an edge. It is rarely one that the market has not already priced, and it tends to make people more confident and less diversified at the same time. Knowing a business well is a reason to understand the risk clearly, not evidence that the stock will outperform.

Taxes and timing shape the how, not the whether

Vested RSUs have already been taxed as income, so selling them soon after vesting usually creates little extra tax. ESPP shares and long-held positions can carry larger gains and different rules for how they are taxed. Trading windows and blackout periods limit when you can act. All of these affect how to reduce a position efficiently, and they are worth discussing with a tax professional, but they do not answer whether the concentration is one you want.

Measuring what holding has done

Your transaction history shows every vest and every sale. Rebuilding the portfolio as it would have been had you sold at each vest and diversified, or had you made no changes at all, shows what holding the concentration has actually been worth. Pure Benchmarks, our own product, scores decisions against the do-nothing baseline from connected holdings and places the portfolio in one of nine standardized risk categories, which makes a concentration visible next to verified investors holding a more typical mix.

Your current platform won't show you how your portfolio ranks against real investors in the same risk category. Create your secure Pure Benchmarks account and see exactly where you stand.

Frequently asked questions

Should I sell my RSUs as soon as they vest?

A common way to think about it: vested RSUs are taxed as if you received cash and bought shares, so ask whether you would buy that much of your employer’s stock with the cash. If not, holding is an active decision to keep a concentration you would not choose. This page is information for comparison and not a recommendation about any holding; tax details are worth confirming with a professional.

How much company stock is too much?

There is no universal limit, but the risk grows with both the size of the position and how much your income depends on the same company. A position that would be moderate in someone else’s portfolio is larger in yours because of the double exposure.

Is it disloyal to sell company stock?

Selling shares is a portfolio decision, not a statement about your employer. Many employees diversify regularly. The loyalty feeling is one of the reasons concentrations persist longer than people intend.

Should I keep my ESPP shares?

The discount is usually captured at purchase. Holding afterwards is a separate decision to keep a position in your employer, and the same fresh-money test applies. Holding periods can affect how gains are taxed, which is worth checking before selling.

How do I know what holding my company stock has cost or gained me?

Compare your actual portfolio with the one you would have had by diversifying at each vest, or by making no changes at all. Pure Benchmarks, our own product, automates the do-nothing comparison from connected holdings.
