I lost money in stocks: what should I do first?

Stop. Do not add to the losing position, do not double your size, and do not switch to options or leverage to make it back faster. The urge to win back a loss at once has a name, revenge trading, and trading psychology explains why it is so strong. The short version: it adds risk exactly when your judgement is at its worst.

Give yourself a few days with no new trades. Cancel open orders you no longer understand, check that no position can lose more than you can afford (margin, short positions and some options can), and write down what happened while it is fresh: what you bought, why, at what size, and what you did as it fell. That page is the raw material for every step that follows.

How much did I lose? The recovery math

Measure the loss as a percentage of the account, not only in dollars, and include paper losses: a stock you still hold at a loss is worth what the market pays for it today, not what you paid. Then look at the gain needed to get back. After a loss of L, the account needs L ÷ (1 − L) to return to where it was: a 20% loss needs +25%, a 40% loss needs +66.7% and a 50% loss needs +100%.

That asymmetry is the strongest argument for patience. A deep hole is climbed slowly, and the maximum drawdown lesson shows how long the climb can take. Trying to climb it in one jump with a bigger position usually makes it deeper.

Realised loss
A loss locked in by selling a position for less than you paid for it.
Unrealised loss (paper loss)
The fall in value of a position you still hold. It is not final, but it is what the position is worth today.

On the left, a hypothetical $10,000 account drops 40% to $6,000, drawn as a red arrow down, and a green arrow back up is labelled +66.7%: the $4,000 needed is two thirds of $6,000. On the right, a small table of losses and the gain needed to recover each: −10% needs +11.1%, −25% needs +33.3%, −40% needs +66.7%, −50% needs +100% and −75% needs +300%. The formula gain = L ÷ (1 − L) is written underneath.

Was it an investing loss or a trading loss?

The fix depends on what kind of loss it was. An investor buys a business for a reason, the thesis: growing sales, a strong balance sheet, a fair price. A trader buys a price setup with an exit plan: entry, stop, target and size. An investing loss asks whether the thesis was wrong or the price simply fell; a trading loss asks whether the rules were wrong or were not followed. Many beginners mix the two: they buy as traders and, once the price falls, become “long-term investors” to avoid selling. Trading vs investing explains the difference.

Then audit honestly. Go through each losing position and tag its main cause. If most of the damage came from one or two causes, those are the rules to fix first:

  • No plan: no reason written down and no exit decided before buying.
  • Too big: one position held a large share of the account, so one drop did most of the damage.
  • No stop, or a stop moved further away as the price fell.
  • A tip, a rumour or a social media post in place of your own analysis.
  • Averaging down into a falling stock without a reason that still held (see averaging down).
  • A sound plan that simply lost: the only cause that needs no fix, because losing trades are part of every method.
Investment thesis
The written reason you own a stock as an investment, specific enough that you could tell when it is no longer true.

Should I sell my stocks at a loss or hold?

The price you paid is not a reason either way. The market does not know your entry, and the money is already lost on paper whether you sell or not. The useful question is: if I had this cash today, would I buy this stock at this price, for a reason I can write in one sentence? If yes, holding is a decision. If not, holding is only hoping. Write the reason down, with what would make you sell and the date you will check again.

For a trade, the answer was set before entry: if the stop is long past, the plan says sell, and buying back later is a new trade with a new plan. For an investment, check the thesis against the latest results. When to sell a stock has a full sell checklist for both. If you need the money within a year or two, that alone is a reason to carry less risk. In some countries a realised loss can offset taxes on gains; the rules differ, so check your own before deciding for tax reasons.

How to recover from a trading loss: restart small

When you come back, come back smaller. Risk a fixed 0.5% to 1% of the account on each trade, size every position from its stop with the position size calculator, and set a daily loss limit after which you stop for the day; risk management covers the limits. Small risk is not timid. It is what lets a method that works show itself, and what keeps a method that does not work from doing more harm.

Recovery then comes from a long run of ordinary trades with a positive expectancy, or from saving and adding new money over time, not from one trade. Trading more is not the way back either: in Brad Barber and Terrance Odean’s study of 66,465 US households from 1991 to 1996, the households that traded most earned 11.4% a year while the market returned 17.9% (Journal of Finance, 2000).

Paper-trade the fix before real money

Before risking money again, test the repaired rules on a paper trading account, or at a very small size, for 20 to 30 trades. The goal is not profit yet. It is to see whether you actually follow the new rules: a written reason before each trade, the stop placed at entry, the size from the calculator, the daily limit respected. Keep a trading journal and count rule breaks as carefully as wins and losses.

Go back to real money only when rule breaks have become rare, and then at the small, fixed risk from the step before.

A worked example: the week after a 40% loss (hypothetical)

Hypothetical: a trader with a $10,000 account bought 200 shares of XYZ at $50 on a friend’s tip, the whole account in one stock, with no stop. XYZ falls to $30. The position is now worth $6,000: a loss of $4,000, or 40%, which needs +66.7% to recover. Here is the plan, step by step:

  1. Pause: no new trades for a week, and no buying more XYZ to lower the average price.
  2. Audit: three causes, all fixable. No plan, the whole account in one position, and no stop. The tip replaced analysis.
  3. Decide: would they buy XYZ today at $30 on its own merits? They cannot say why they would, so they sell and keep $6,000 in cash instead of holding on hope.
  4. Paper-test: 25 practice trades, each with a written reason, a stop and 1% risk.
  5. Restart small: with $6,000 and 1% risk, a trade risks $60. A long at $30.00 with a stop at $28.50 risks $1.50 a share, so 60 ÷ 1.50 = 40 shares, a $1,200 position.
  6. Check the downside: five losses in a row at 1% would cost about $294, or 4.9%, instead of another 40%.

Two hypothetical panels side by side. Before: 200 shares of XYZ at $50, the whole $10,000 account in one position with no stop; the bar of money at risk fills the account, and a red note says at $30 the loss is −$4,000, or −40%. After: a $6,000 account with 1% risk, a long at $30.00 with a stop at $28.50, so $1.50 a share and 40 shares, a $1,200 position; only a thin red slice of $60 is at risk, and a note says five losses in a row would cost about $294, or −4.9%.

When trading starts to look like gambling

Sometimes the problem is not the rules but the pull to keep trading. Health services use simple self-checks for gambling, and the questions carry over to trading almost word for word. The UK’s NHS, for example, asks whether you bet more than you can afford to lose, chase losses, borrow money or sell things to keep going, feel guilty about it, or find that it causes stress, anxiety or money problems at home.

If several of those sound familiar, stepping back is a strength, not a failure. Tell someone you trust, remove the trading app or ask your broker about limits or closing the account for a while, and talk to a doctor or a local support service. Your savings and your health are worth more than any trade.
