How Long Should I Hold a Losing Trade?

The dollar figure on a losing trade tells you almost nothing about whether to stay in it.

A red number of 400 might be a normal wobble on a large position or a disaster on a small one. What it cannot tell you is whether the idea still holds. Every trade is a bet on something specific happening within some period, and it should end when either half of that bet fails: price proves the idea wrong, or the period passes without the idea playing out.

Whichever comes first.

The price exit

Say you buy 300 shares at 25.00 because the stock broke above 24.50, a level where it had stalled several times. The idea is that the breakout holds. A close back below 24.20 means it did not.

That level is your exit. It was set before the trade, from the chart. How much money it represents depends on the share count, which you also chose before entry, so once you are in the trade the dollar loss carries no new information at all and only the price relative to 24.20 does.

Put the level in as a real stop order at the broker. A level you plan to act on “when it gets there” tends to move when it gets there; see why mental stops fail.

The time exit

Now say the stock never touches 24.20. It drifts between 24.60 and 25.10 for a week and a half.

No stop hit. Also no trade.

A breakout that does not follow through within the window you expected has failed in a quieter way, and holding it ties up capital, attention and margin you could use on a setup that is working. Decide the window at entry. A swing trade might get a set number of sessions. A day trade might get until a time of day, after which you close it whatever it shows.

When the time runs out, exit or cut the size. Do not reset the clock because the price is close to your entry.

Signs you are holding for the wrong reason

• You are waiting to get back to even. Your entry price means nothing to anyone else in the market.
• You added to it. Buying more to lower the average price, without a plan made before entry, turns one mistake into a bigger one.
• You moved the stop. Once is a warning.
• You stopped checking it. Hiding from a position is different from hiding the dollar P&L to judge it on price.
• It became a long-term investment. Nothing about the trade changed except the loss.

One more check. A stock falling because the whole market fell is a different situation from a stock falling on its own bad news, and the reasons to hold differ too, as single-stock dips versus index dips sets out.

The arithmetic of getting back

Losses and the gains needed to repair them are not the same size. The recovery is always measured from the smaller, post-loss amount.

The gap between the loss and the repair widens the deeper you go, which is why a trade held from minus ten to minus twenty to minus fifty percent in the hope of recovery keeps asking for a larger and less likely move just to get back to where it started. Cutting at the planned level keeps the repair small.

If you are holding a loser right now

Write down, in one sentence, why you bought it. Ask whether that sentence is still true at today’s price. Write down the date by which it should have worked. If the reason is broken or the date has passed, close it; if both still hold, enter a real stop at the level that would break the reason. If the loss is part of a bad session, the steps in what to do after a big losing day come first.
