Free toolHow much of your wealth rides on one company’s stock?
RSUs, ESPP shares and exercised options from the same employer pile up fast — and your salary already depends on that company. If one stock is a big share of your investable wealth, a single bad quarter hits your portfolio and your paycheck. See your concentration in ten seconds, with a plain-English read.
Education only — not investment advice. There is no universally “right” level of concentration; it depends on your goals, your income, your other safety nets and your own tolerance for risk. This tool simply shows the maths and a general frame so you can have a better conversation with a qualified financial adviser. Selling also has tax consequences — factor those in.
What to do next
Decide your own ceiling
Pick a share of wealth you’re comfortable having in one stock, and treat vesting RSUs and ESPP buys as a reason to rebalance back toward it.
Mind the tax on selling
Selling to diversify can trigger capital gains. The order you sell lots in, and how long you’ve held, both matter — worth a word with a tax adviser.
