Deep In The Money Covered Calls: The Strategy Most Traders Overlook (And Why It Works)

Most options traders learn covered calls as an OTM strategy. You own 100 shares, you sell a call above the current price, you collect premium, and you hope the stock stays below your strike. Simple. Clean. Widely taught.

Deep in the money covered calls work completely differently — and most traders either ignore them or misunderstand what they're actually for.

Here's what DITM covered calls actually are, when they make sense, and what the math looks like when you run the numbers honestly.

What "Deep In The Money" Actually Means

A covered call is "in the money" when the strike price is below the current stock price. A call with a $45 strike on a $50 stock is $5 in the money. A call with a $35 strike on that same $50 stock is $15 in the money — that's deep in the money.

When a call is deep in the money, its premium is almost entirely intrinsic value. Intrinsic value is the difference between the stock price and the strike — in our example, $15. The extrinsic value (time premium) is very small because the option is so far in the money that time decay doesn't add much to the equation.

This matters because when you sell a DITM covered call, you're not really selling time premium the way you do with an OTM call. You're essentially agreeing to sell your shares at a price that's already below the current market — and getting paid a large upfront credit to do it.

Why Traders Use Deep In The Money Covered Calls

There are three legitimate reasons to sell a DITM covered call rather than an OTM one:

Lower breakeven. When you sell a DITM call, the premium you collect is much larger than an OTM call. That premium reduces your effective cost basis on the shares. If you paid $50 for a stock and sell a $40 strike call for $12, your breakeven drops to $38. The stock can fall to $38 before you lose money — much more cushion than a $2 OTM premium gives you.

Predictable return at expiration. If the stock stays above your strike, you get assigned and your shares are called away at the strike. With a DITM call, assignment is almost certain — the stock would need to fall significantly to avoid it. That certainty is actually useful when you want a known outcome rather than hoping the stock stays in a range.

Exiting a position while getting paid. If you want to sell your shares anyway but want to extract extra premium while doing it, a DITM covered call is a clean mechanism. You'll almost certainly get assigned, your shares will be called away, and you'll have collected a larger credit than you would have selling at market.

When This Setup Actually Makes Sense

DITM covered calls work best in specific situations — and they're the wrong tool in others.

You're neutral to mildly bearish on a stock you want to hold. If you think a stock is going to trade flat or drift slightly lower over the next 30-45 days, selling a DITM call gives you substantial downside cushion and a known return at expiration. You're not betting on upside — you're monetizing the position while you wait for a better entry point.

You're in a flat to slowly rising market. In a strongly trending bull market, DITM covered calls are expensive — you cap your upside right as the stock wants to run. In a flat, range-bound, or slowly grinding market, that capped upside costs you nothing because the stock wasn't going anywhere anyway. The rich premium is pure income.

You want to reduce your cost basis aggressively. If you're underwater on a position and want to lower your breakeven while you wait for a recovery, DITM covered calls can reduce your effective cost basis much faster than OTM calls. The tradeoff is you cap your recovery upside — but if you just want to get back to even, that might be a worthwhile trade.

The Math on a Real Example

Let's walk through a concrete trade so the numbers are clear.

Setup: You own 100 shares of XYZ at $50. You sell the $42 strike covered call expiring in 35 days for $9.50.

Premium collected: $9.50 per share, $950 total.

Your effective cost basis: $50 - $9.50 = $40.50 per share.

Max gain: If assigned at $42, you receive $42 per share. Your profit is $42 - $40.50 = $1.50 per share, or $150 total. That's a 3% return on your $50 cost basis in 35 days — roughly 31% annualized.

Breakeven: $40.50. The stock needs to fall below $40.50 before you lose money on the combined position.

Compare to an OTM alternative: If you had sold the $55 strike call instead for $1.20, your breakeven would be $48.80, your max gain would be $6.20 per share ($7 gain on shares + $1.20 premium), and you'd have far less downside protection but much more upside exposure.

Neither trade is better in the abstract — it depends entirely on what you think the stock is going to do and what kind of return profile you want.

The Hidden Risk Nobody Mentions: Early Assignment

This is the part that catches traders off guard.

Deep in the money calls get exercised early far more often than OTM calls. Here's why: when a call is deep in the money, there's almost no time premium left — the option's value is almost entirely intrinsic. The option holder has little reason to hold the call rather than just exercise it and take the shares, especially if there's a dividend coming.

Early assignment means your shares get called away before expiration — sometimes days or weeks before you expected. This isn't necessarily a problem if you planned for it, but if you weren't expecting it, it can disrupt your position management.

Two specific situations where early assignment is most likely: when there's a dividend coming before expiration (call holders will exercise to capture the dividend), and when the extrinsic value of the call drops to near zero. If you're selling DITM covered calls, check the ex-dividend date and watch the extrinsic value on your call. When it approaches zero, assignment could happen any day.

How to Find Deep In The Money Covered Call Setups

Scanning for DITM covered calls manually is tedious. You need to find stocks where the premium on ITM strikes is actually worth selling — meaning there's enough extrinsic value to make the trade worthwhile, the stock has reasonable IV, and there are no imminent catalysts that could blow up the position.

I built a covered call screener into StrikeScan for exactly this — you can filter by strike moneyness, premium, probability, IV rank, and earnings proximity across thousands of tickers at once, updated every 15 minutes. Free to use right now at StrikeScan.com.

The Bottom Line on DITM Covered Calls

Deep in the money covered calls are not a beginner's consolation prize. They're a deliberate tool for specific market conditions — when you want maximum downside cushion, a known exit price, or aggressive cost basis reduction on a position you're ambivalent about holding.

The trade-offs are real: you cap your upside hard, early assignment is a genuine risk, and in a strongly bullish market you'll wish you had sold OTM. But in flat, choppy, or slowly declining markets, the DITM covered call is one of the cleanest income trades you can make on a stock you already own.

Know when to use it. Know the math. Watch for early assignment. The rest is execution.
