The strike-below-cost trap, with the table

The trap is selling covered calls with strikes below what you paid, because the higher strikes pay too little. It collects more premium every month, then locks in a loss the day the stock bounces.

The short answer

The strike-below-cost trap is selling a Covered call with a Strike price under your cost per share, without having decided to exit there. It feels like making the best of a bad spot. What it really does is agree, in advance, to sell at a loss if the stock recovers.

It's a common covered-call mistake in the wheel strategy, because it happens one small, reasonable-looking step at a time.

How the trap starts

It usually follows the same path:

1. You're assigned shares, or you own shares that have dropped.
2. You go to sell a call at your cost. It pays almost nothing.
3. A strike a couple of dollars lower pays several times more. You sell that one.
4. Next month, the stock is a bit lower. You step the strike down again.
5. One day the stock bounces hard. You're called away under your cost. The loss you'd been hoping to wait out is now locked in.

Each step makes sense on its own. Together, they turn a temporary loss into a permanent one.

The strike-by-strike table (an illustration, not a trade idea)

You own 100 shares of a made-up stock, XYZ, with a cost of $50. It's fallen to $44. Here are 30-day calls you could sell:

Read it one column at a time.

• "If XYZ falls to $38": every strike loses about the same. The premium barely changes the loss. A lower strike doesn't protect you.
• "If XYZ rebounds to $52": the lower the strike, the worse you do. The $44 call turns a rebound into a −$440 loss.
• "If called away": any strike under $50 locks in a loss. At or above $50, it can't.

So the extra premium from a low strike buys almost nothing on the way down, and costs a lot on the way up.

Three months in the trap

Here's how it plays out over time, with the same XYZ and a $50 cost.

Now the same three months, selling calls only at your $50 cost:

The trap collected five times more premium. It also finished $395 worse. The premium was real. So was the price you agreed to sell at.

Why it feels right at the time

• The at-cost call pays almost nothing. It feels like wasted time. But the small premium is the market saying the stock is far from your cost. That's information, not a problem to fix.
• "Something is better than nothing." Not when the something includes a promise to sell low.
• "It probably won't get there." Probably. But the one month it does is the one that sets your result.
• Watching a red position is hard. Doing something feels better than waiting. Waiting can be the right something.

How to stay out of it

Set one rule and write it at the top of your journal:

I sell calls at or above my cost, unless I've decided to exit at a lower price.

That second half is important. There is a fair use for a call below cost: when you've already decided to leave this stock, and you'd sell at that price anyway. Then the call is a sell order that pays you to wait. Our page on selling a call below your cost basis covers that case.

A few more habits help:

• Track your real cost. Every premium lowers it a little. Use the cost basis calculator.
• Accept small premiums while the stock is low. Or sell no call at all for a while.
• Re-check the business. If you wouldn't buy it at today's price, the problem isn't the strike. See when to stop wheeling a stock.
• Never step the strike down two months in a row without writing why.
