The Moment
The market just dropped 20% and your portfolio is down significantly.
This is the moment that separates investors who build wealth from investors who destroy it. Not because of what the market does next, but because of what you do next.
What the Data Shows
Since 1950, the S&P 500 has experienced 12 bear markets (declines of 20% or more). Every single one has been followed by a recovery to new highs. The average bear market has lasted about 14 months. The average recovery to prior highs has taken about 27 months.
Investors who sold at the bottom of the 2009 bear market and waited to re-enter missed one of the longest bull markets in history. Investors who sold in March 2020 missed a 100% recovery in 12 months.
Market Drop — Stay or Sell?
Markets are down. Selling locks in losses; staying invested participates in the recovery. The math of staying-vs-selling, framed honestly.
Educational illustration — not financial advice. Uses constant-rate compound growth; real markets are bumpy. Time-in-market is the dominant lever, but the order of returns matters too (sequence-of-returns risk in early retirement).
What to Do
Do not sell. This is the most important action. Selling locks in losses and creates a re-entry problem — you now have to decide when to buy back in, which is a second market-timing decision.
Check your liquidity. If you have 3-6 months of expenses in cash, you do not need to sell investments to cover living expenses. This is why the emergency fund exists.
Rebalance if your allocation has drifted. A 20% drop in equities may have pushed your portfolio below your target stock allocation. Rebalancing — buying more equities to restore the target — is the disciplined response.
Consider tax-loss harvesting. If you hold investments in a taxable account that are now below your cost basis, you can sell them, capture the tax loss, and immediately reinvest in a similar (not identical) fund.
What Changes the Answer
Time horizon. If you need the money in under 3 years, a 20% drop is a real problem because you may not have time to recover before you need to sell. This is why short-horizon money should not be in stocks.
Emergency fund status. If you do not have 3 months of liquid expenses, a market drop creates pressure to sell at the worst time. Build the fund before investing in equities.
Your actual allocation. If a 20% market drop has caused you genuine distress, your equity allocation may be higher than your real risk tolerance supports. A bear market is the best time to recalibrate — after you have stayed invested through it.

Frequently Asked Questions
Should I sell everything when the market drops 20%?
No. Selling at a 20% loss locks in that loss and creates a re-entry problem. Every bear market in US history has been followed by a recovery. The investors who stayed invested recovered; those who sold did not.
Should I buy more when the market drops?
If your allocation has drifted below target, rebalancing by buying more equities is the disciplined response. If you have excess cash, deploying it during a bear market is historically one of the best entry points.
How long does it take to recover from a 20% market drop?
Historically, the average time to recover from a bear market to prior highs has been about 27 months. Some recoveries have been faster (2020: 5 months) and some slower (2000-2002: 7 years). Time horizon is the key variable.
