What is Covered Call?
A covered call sells a call option while holding the underlying shares. Premium income trades against capped upside if stock rallies hard.
Formula
Covered Call Example: Own: 100 shares at $100 ($10,000 investment) Sell: 1 $105 Call expiring in 30 days Premium Collected: $2.00 per share ($200) Scenarios at Expiration: Stock at $110 (above strike): Sell shares at $105 Keep $200 premium Total: $105 + $2 = $107/share Profit: $700 (but missed $300 upside) Stock at $100 (unchanged): Keep shares worth $100 Keep $200 premium Cost basis reduced to $98/share Stock at $95 (down): Keep shares worth $95 Keep $200 premium Loss reduced: $500 - $200 = $300
Indian market context (NSE)
Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Covered Call shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
Nifty at 24,300: weekly/monthly option chains centre on round strikes (24,000 / 24,500). Covered Call on ATM Nifty options shifts quickly into expiry — India VIX and event risk (RBI, budget) reprice premiums independent of spot.
Reliance Industries perspective
Reliance at ₹1,300: stock options are American-style on NSE with liquidity concentrated near ATM strikes. Covered Call behaviour on ₹1,300 handle differs from index options — watch assignment on short ITM legs before expiry.
Bank Nifty futures perspective
Bank Nifty futures at 55,000: hedging with options or trading covered call on Bank Nifty weekly contracts — theta and gamma rise sharply into Thursday expiry; futures leg has no time decay but carries overnight gap risk.
How to validate

- Stress-test with expiry-week and event-week subsets (RBI, budget, results).

A call option grants the buyer the right, not obligation, to buy the underlying at the strike before or at expiry, depending on contract style.
A credit spread nets premium upfront with risk capped by the long protective leg. Bull put and bear call variants are common on NSE.
Strike price is the level at which the option buyer can transact the underlying. Moneyness (ATM, ITM, OTM) drives delta, premium, and liquidity.
Theta measures expected premium change from passage of time, holding other factors constant. Long options usually have negative theta; short options collect theta.
