Every investor who stays in the market long enough will watch their portfolio fall a long way. What separates the ones who come out fine is rarely what they owned; it is what they did in the middle of the fall. A practice account cannot make a drawdown hurt, but it is the best place to rehearse your response before it does.
Losses and gains are not symmetrical. After a fall, you are compounding back from a smaller base:
| Drawdown | −10% | −20% | −25% | −33% | −50% |
|---|---|---|---|---|---|
| Gain needed to get back | +11% | +25% | +33% | +49% | +100% |
A $100,000 account that falls 25% to $75,000 needs $25,000 of gains to recover — which is 33% of $75,000, not 25%.
These are declines in the S&P 500 price index, peak to trough, measured on closing prices:
| Episode | Decline | Peak → trough | Back to the old high |
|---|---|---|---|
| Global financial crisis | about −57% | Oct 2007 → Mar 2009 | Early 2013 — about four years after the bottom |
| COVID-19 crash | about −34% | Feb 2020 → Mar 2020 (roughly a month) | Aug 2020 — about five months after the bottom |
| 2022 rate-hike bear market | about −25% | Jan 2022 → Oct 2022 | Jan 2024 |
Two lessons sit in that table. Declines of 25% or more are not rare events; they have happened three times in under twenty years. And recovery time varies enormously, so a plan that depends on a quick bounce is a hope, not a plan. Individual stocks fall much further than indexes — a 60% or 70% drawdown in a single company is common even among businesses that survive.
A virtual loss does not hurt, which is exactly why a practice account can teach the wrong reflexes. Two habits help.
Translate to your real scale. In Module 1 you wrote down the amount you would really invest. When the practice account is down 15%, write the real-money figure next to it: on $20,000, that is $3,000. Then ask whether you would have held.
Compare against your stated tolerance. You also wrote down the loss you thought you could live with. If the account passes it, that is the most valuable data point the simulator will ever give you — either your tolerance was lower than you believed, or your portfolio is riskier than your plan.
Decisions made in the middle of a decline are made by the most frightened version of you. Rules written in advance are made by the calmest. Useful ones are specific and say what triggers a review, not an automatic sale:
Revenge trading. Taking bigger or faster trades to “win back” a loss. The market has no idea you lost money and owes you nothing; the urge to get even is the single most reliable route to turning a manageable loss into a large one.
Doubling down. Buying more of a falling position purely to lower the average cost so a smaller bounce gets you back to break-even. Adding can be right when the business is intact and the position is still within its limit. Adding because of your entry price is about your feelings, not the company.
Overtrading. Selling one thing and buying another every few days to feel in control. Every trade in real life costs a spread, sometimes a commission, and sometimes tax.
The trade history records what you did. A journal records why, and that is the half you need to learn anything. Keep one line per trade in your notes:
| Date | Action | Ticker & size | Why, in one sentence | What would prove me wrong | Emotion (1–5) | Review on |
|---|---|---|---|---|---|---|
| Sep 13 | Buy | XYZ, 4% | Revenue growing 15% a year at a below-sector P/E | Two quarters of falling revenue | 2 — calm | After next earnings |
After a drawdown, read the journal back. Trades logged at emotion 4 or 5 are the ones to study first.
