Covered Call

A covered call is selling a call option against 100 shares of stock you already own. You collect premium up front; in exchange, if the stock closes above the strike at expiration, your shares get called away at that price. It’s the simplest options strategy that exists, and for most traders it’s the right place to start.

The structure

For every 100 shares of stock you own, you can sell one call option. The strike you pick determines the trade-off between premium collected and upside given up:

• Far OTM (low delta, ~10-15):tiny premium, almost no chance of being called away. Best when you really don’t want to lose the shares.
• Moderate OTM (delta 0.20-0.30): the Tradient default. Healthy premium, ~75% chance the call expires worthless. Best for income-focused holders.
• Near ATM (delta 0.40-0.50):fat premium, coin-flip on assignment. Best if you’d be happy to sell at the strike anyway.

Worked example

You own 100 shares of AAPL at a cost basis of $180. AAPL is trading at $190. You sell the 30 DTE 200 call (delta ~0.25) for $2.50 in premium.

• Premium collected: $250
• Effective max sale price: $200 + $2.50 = $202.50/share
• Annualized return on the $190 stock: ~16% (250 / 19000 × 365 / 30)
• Breakeven on the stock + call combo: $190 − $2.50 = $187.50

If AAPL stays below $200, the call expires worthless and you keep the $250 free and clear. If AAPL closes at $205, you sell your shares for $200 each (net $20,250 including the premium) — you give up $250 of upside but you’ve already pocketed that as premium, so the net is the same as if you’d sold at $202.50. If AAPL crashes to $170, you’re down on the stock, but the $2.50 cushion offsets a small chunk of that loss.

When to use it

• You own the stock and intend to keep owning it. Covered calls only make sense as an overlay on a position you already have. Don’t buy stock just to write covered calls — that’s a different (and worse) trade.
• Your view on the stock is neutral to mildly bullish.If you’re actually bullish, the covered call caps your upside in exchange for a small premium — you’re leaving money on the table. Switch to a naked long position or a call spread.
• IV is at least 15-20%.Below that, the premium isn’t worth the upside cap.
• 30-45 DTE. Theta is steepest in this window. Closer to expiry and the premium is too small; farther out and you commit too much time.

How Tradient ranks them

The covered call scanner walks every OTM call in your DTE window across your watchlist, filters by IV floor, delta band, and minimum annualized return, and prices the trade. By default it returns the top 20 sorted by annualized return, then the Tradient Score layer reranks by composite quality.

Capital sizing for covered calls is special: collateral is the cost of the stock itself (stock_price × 100). That makes covered calls capital-intensive even though the option leg itself is cheap. Tradient surfaces this honestly — the “collateral required” column reflects the stock cost, not the call premium.

The wheel

Covered calls are half of “the wheel,” the most common multi-leg income strategy in retail options:

• Step 1: sell cash-secured puts on a stock you’d be happy to own.
• Step 2: if assigned, you now own 100 shares at the strike. Switch to selling covered calls against the position.
• Step 3: if the calls get assigned, you sell the shares at the strike (presumably for a profit on your cost basis). Go back to step 1.

Run together, the wheel is a continuous premium-collection machine on a single stock. Tradient’s “Wheel candidates” library scan exists specifically to find the right step-1 entries.

Managing the trade

Rolling for credit

If the stock rallies through the strike before expiration and you don’t want to be called away, you can roll the call: buy back the current call and sell a further-dated, higher-strike call for a net credit. This buys time and pushes the assignment threshold up. Works as long as the rolled trade collects net credit — never roll for a debit.

Rolling down

If the stock has fallen and the original call is now near-zero, you can buy it back early (locking in most of the premium) and resell a closer-to-the-money call to collect more. This is aggressive — you’re shrinking your upside cushion in exchange for more premium.

Common mistakes

• Writing calls on stock you actually love. The whole point of covered calls is acceptance: if the call gets assigned, you’re fine selling at that price. If you have a multi-bagger thesis on the underlying, don’t cap your upside for $250.
• Selling too far OTM in low IV. A $0.20 premium on a $200 stock is rounding error. Either move closer to the money or skip the trade.
• Ignoring ex-dividend dates. Calls trading ITM near a dividend date can be exercised early to capture the dividend. Tradient flags this in Focus mode.
• Forgetting cost basis.If your cost basis is $180 and you keep writing $190 calls in a falling market, you’re collecting nickels while the stock loses dollars. Cover the calls and reassess.
