Stock down 50%: should you sell or hold?

Ask one question. Would you buy this stock today, at this price, with fresh money? If no, selling makes sense. If yes, holding does. Your old buy price shouldn't get a vote.

Why half has to double to get you back

When a stock falls 50%, it needs to rise 100% to get you back to even. It has to double. This surprises almost everyone.

Here's why. Say you put in $10,000 and it falls to $5,000. A 50% gain on $5,000 is only $2,500. You'd be at $7,500, still down. To get back to $10,000, the $5,000 has to grow by another $5,000. That's 100%.

Run your own numbers in the loss recovery calculator.

This doesn't tell you to sell. A stock can double. But it tells you something honest: holding and waiting is a bet that this stock will double. Ask yourself if that's a bet you'd make today.

The one question: would I buy it today?

Forget what you paid. Picture someone handing you the stock's current value in cash. Same amount. You can buy anything.

Would you buy this stock with it, at today's price?

• Yes, gladly. Then holding is a fair choice. You already own what you'd buy.
• No, not a chance. Then you're only holding to get back to your old price. That's a feeling, not a reason. Selling and using the money elsewhere makes sense.
• Not sure. Then you're probably holding too much of it. Trimming some is a fair middle path.

Your buy price feels important. It isn't, to the market. The stock doesn't know what you paid. Holding on just to "get back to even" is the Sunk cost fallacy: letting money already lost decide what you do next. And getting stuck on your buy price is Anchoring bias. Both feel like good sense. Both are traps.

Check the reason you bought it

Write down, in one sentence, why you bought this stock. Then ask: is it still true?

• You bought it for the business. Did the business break? Sales collapsing, debt piling up, a product that failed? Or did the whole market just fall and drag it down?
• You bought it because it was going up. Then the reason is already gone. It isn't going up.
• You bought it because someone online said so. Then you never had a reason of your own. That's worth knowing, and it's fixable.

A stock that fell with the whole market is a different story from one that fell alone. But neither one comes with a promise. Some fallen stocks come back. Some take years. Some go to zero.

Check the size: how much of you is in it

Now the money side. How big is this stock compared with everything you have?

If it's a small slice, you can afford to be patient. If it's most of your savings, the risk is too big whatever the stock does next. Ask: if it fell by half again, could I live with that?

Also ask: do I need this money in the next year or two? Money for rent, a house, school or bills shouldn't be riding on one stock that just showed it can halve.

A worked example (hypothetical): hold, sell or trim

Alex bought 100 shares of a made-up stock, XYZ, at $100. That cost $10,000. XYZ is now $50. Alex is down −$5,000.

Alex has three choices. Here's how each one ends in two different futures. Nobody knows which future comes.

Look at the top row. If XYZ keeps falling, holding turns −$5,000 into −$7,500. That's the losing case, and it happens. Plenty of stocks that fell 50% went on to fall more.

Look at the bounce column. Even if XYZ climbs 40% from $50 to $70, Alex is still down $3,000 by holding. A big bounce isn't the same as getting back.

The middle choice, trimming, is never the best and never the worst. That's its job. It's for when you can't answer the "buy it today?" question with a clear yes or no.

The decision, on one card

Whatever you pick, wait 24 hours before you act. Then write the choice and the reason in your journal. See how to stop panic selling for the full wait rule.

A tax note: selling at a loss in a regular taxable account can often offset gains. Buying it back too soon can cancel that, and losses inside an IRA, TFSA or RRSP don't count. Check the IRS or the CRA for your case.

Some holders sell covered calls on a stock that's down, to collect a premium while they wait. It can help, but it can also lock in a loss if the shares get called away below what you paid. See covered call when the stock goes down, and the wheel strategy for how calls and puts fit together. For the bigger picture after a loss, start with what to do after losing money in stocks.
