🛡 Covered & Protective

Covered Call/Put, Cash-Secured Put, Married Put, Protective Call és Collar

1. Covered Call

📉 Neutral/Bearish Stock owner · regular premium income

You own 100 shares and simultaneously sell an OTM call option on them. The premium is immediate income but caps your upside at the strike.

When to use: You hold a stock long-term and expect no strong price appreciation in the next option period. Classic income strategy ("renting out your shares").

What really happens at assignment

Scenario: You own 100 AAPL at $170 (cost basis) and sold a call with strike $185. AAPL closes on expiration day at $190 — in the money (ITM) from the call's perspective.

  1. Saturday morning: Broker automatically removes your 100 AAPL shares from the account.
  2. Cash credit: 185 × 100 = $18,500 is credited to your account. The call premium (e.g. $3.00/share = $300) stays in your pocket on top.
  3. Effective profit per share: (185 − 170) + 3.00 = $18.00 per share = $1,800 total. You miss the move above $185 — that is the price of the strategy.
  4. What now? If you want to keep trading AAPL: sell a new CSP on AAPL (Wheel strategy back to start), or use the cash for another underlying.

💡 In sTraderZ.com automatically recognised as "Covered Call" (📉 Bearish) when you hold 100 shares + 1 short call.

2. Covered Put

📈 Neutral/Bullish Short seller · premium income

You are short a stock and simultaneously sell an OTM put option. The counterpart to the covered call for short positions.

When to use: You hold a short stock position and expect no strong downward price movement. Less common in practice than the covered call.

💡 sTraderZ.com recognises Covered Put when a short stock position + short put on the same underlying are present.

3. Cash-Secured Put

📈 Bullish/Neutral Seller · stock-equivalent premium

Like a short put, but you hold the required cash (Strike × 100) ready to actually buy the stock if exercised. This makes the strategy fully covered.

When to use: You want to buy a stock at a discount and get paid premium for it. "I'm willing to buy Apple at $95 — pay me $3 for the obligation."

4. Married Put

📈 Bullish Stock owner + long put · insurance

You simultaneously buy 100 shares and a put option on them. The put acts like insurance: if the stock falls, the put limits your loss to Strike − Purchase Price + Premium.

When to use: You buy a stock and want to protect against sharp losses (e.g. before earnings). "Buying shares with a safety net."

5. Protective Call

📉 Bearish Short stock owner + long call · hedge

When to use: You are short a stock and want to protect against sudden price spikes.

6. Collar

↔️ Neutral Stock owner · limits upside & downside

You hold 100 shares, buy an OTM put (downside protection) and finance it by selling an OTM call (upside cap). Often zero-cost or low net cost.

When to use: You want to cheaply hedge an existing stock position without deploying much capital. Popular with large positions or ahead of uncertain periods.
