Managing a Concentrated Position After an IPO Lockup Expires
Key takeaways
- A lockup expiration makes shares sellable; it does not tell you when or how much to sell.
- Lockup-expiration days often see elevated volatility and selling pressure, which is a risk if you wait to act in size.
- Your holding period and basis determine the tax — founder and early-employee shares are often low-basis and long-term.
- A collar can protect paper gains immediately, even before you decide how fast to sell.
- Insiders still face 10b5-1 and trading-window rules after the lockup lifts.
For months after an IPO, your shares look valuable on a screen and are completely untouchable. Then the lockup expires and the constraint flips overnight: now you can sell, and the question is no longer “can I?” but “how, and how fast?” The paper wealth is real, but so is the risk that it shrinks before you act.
What changes the day a lockup expires?
The lockup is a contractual agreement, usually 90 to 180 days, barring insiders and early holders from selling after the IPO. When it lifts, a large block of previously restricted shares becomes eligible to trade. That often coincides with increased volume and price pressure, because many holders are eligible to sell at once. The expiration removes a legal constraint; it does not remove market risk, and in the short term it can add to it.
How fast should I sell after the lockup lifts?
There is no single answer, but the framing helps. Selling everything immediately maximizes diversification and locks in the value, at the cost of a potentially large tax bill in one year and forgone upside if the stock keeps climbing. Holding everything keeps full exposure to a young, volatile, single company. Most holders land in between: trim enough to cover near-term needs and reduce the most acute concentration, then pace the rest. A pre-set schedule removes the temptation to time the market.
- Define how much single-stock exposure you are willing to keep, in dollars, before you look at the tax.
- Sell higher-basis lots first where possible to reduce the tax per share sold.
- Consider protecting the remaining position so a post-lockup drawdown does not erase the gains.
How is the sale taxed for founders and early employees?
It depends on what you hold and how long you have held it. Founder shares and early-exercised options are often very low-basis and, by the time the lockup lifts, may already be long-term — taxed at long-term capital gains rates on the full appreciation. Recently vested RSUs carry vest-date basis and little embedded gain. If you exercised qualifying stock early, you may also want to check whether the position could qualify for special small-business stock treatment, which can materially change the math. A tax advisor should confirm your specific lots.
Example: illustrative
Imagine a founder holding 200,000 shares with a basis near $1, trading at $30 post-IPO. The embedded gain is roughly $29 per share, almost all of it. Selling the entire block in one year would realize a $5.8M gain at once. Spreading sales across multiple tax years, while hedging the unsold shares, can soften both the tax timing and the price risk. These are hypothetical, illustrative figures, not Yayati results.
Can I lock in the value before I decide how to sell?
Yes, and this is often the most useful first move. A collar — buying a protective put and selling a covered call against the position — sets a floor under the value and a ceiling above it, frequently at low or zero net premium cost. That lets you protect the paper gains the moment the lockup lifts, then decide the sell-down pace deliberately rather than under pressure. It does not eliminate risk or guarantee a price; it defines a range you hold within while you plan.
