How Much Company Stock Is Too Much, The Number Nobody Runs
Most people estimate how much of their net worth sits in their employer's stock by opening one app and checking one balance. That balance is usually the smallest piece of it. The real figure includes vested shares held elsewhere, unvested RSUs already scheduled on a calendar, ESPP shares, and employer stock inside the 401(k) if the plan offers it. The piece almost nobody counts is their own future earnings, which are a claim on the same company. Thirty percent of assets in employer stock plus a hundred percent of income from that employer is a very different exposure than thirty percent of assets and forty percent of income. This walks through how to run both numbers. Then the part that gets skipped: knowing the number doesn't automatically mean selling. Research by Hendrik Bessembinder (Journal of Financial Economics, 2018) found that 58% of US common stocks from 1926 to 2016 had lifetime returns below one-month Treasury bills, and that the entire net gain of the US market came from the best-performing 4% of listed companies. But a large appreciated position carries a real cost to unwind. Per IRS Topic 409, long-term gains run 0%, 15%, or 20% federal, and per IRS Topic 559 a 3.8% net investment income tax applies above $200,000 single / $250,000 married filing jointly of modified AGI, with California taxing the gain as ordinary income. Four levers get covered with the tradeoff named on each, and none of them get resolved, because the right answer depends on your basis and your bracket.
