What Is a Covered Strategy in Short Options?

A covered strategy in short options means the seller backs the position with real collateral — either the underlying shares or enough cash — so potential losses stay measurable and capped instead of open-ended. On Pluang, every Short Options trade must use a covered strategy, for both Short Call and Short Put positions; naked (uncovered) short options, where the seller holds no offsetting collateral, are not available on the platform. Selling a naked call exposes the seller to theoretically unlimited losses if the underlying stock keeps rising, while a naked put still carries substantial risk down to a share price of zero. A covered call requires the seller to already hold the underlying shares as collateral, while a cash-secured put requires the seller to set aside enough cash to buy the shares at the strike price if assigned. Both structures let the seller collect the option premium while keeping the worst-case outcome contained and predictable.

The two covered strategies Pluang supports:

• Covered Call (Short Call with stock collateral): You sell a call option while already holding the underlying shares. If the stock price rises past the strike price and the contract is exercised, you simply deliver shares you already own — you don't need to buy them at a higher market price to cover the assignment. Any loss on the option position is offset, at least partly, by the gain in the value of the shares you hold.
• Cash-Secured Put (Short Put with cash collateral): You sell a put option while setting aside cash sufficient to buy the shares at the strike price. If the contract is exercised, you use that reserved cash to buy the shares — a price you already agreed to, so the outcome stays predictable even if the market price has fallen further below the strike.

Because Pluang's US Stock Options are American-style, the buyer of the contract can exercise at any point before expiry, not only on the expiry date itself — so the collateral behind a covered strategy needs to stay in place for the full life of the contract, not just be checked once at expiry.

Q: What's the difference between a covered call and a cash-secured put?
A covered call backs a short call with shares of the underlying asset you already hold; a cash-secured put backs a short put with cash reserved to buy shares at the strike price. Both count as covered strategies because the seller holds collateral that matches the obligation taken on. The right choice depends on market direction — a covered call fits a seller comfortable selling shares they own if the price rises, while a cash-secured put fits a seller comfortable buying more shares if the price falls to the strike.

Q: Can I place a naked (uncovered) short options trade on Pluang?
No. Pluang requires every Short Options position — Short Call or Short Put — to use a covered strategy, so naked short options are not available on the platform. A naked short call has no offsetting shares or cash behind it, which means losses can keep climbing without a practical limit if the underlying stock rises sharply. Pluang's covered-only rule exists specifically to keep potential seller losses measurable rather than open-ended.

Q: What happens if my covered short option gets assigned?
If your short option is assigned, the collateral you already set aside covers the obligation automatically — a covered call surrenders shares you hold, and a cash-secured put uses cash you've reserved to buy shares at the strike price. Because Pluang's options are American-style, assignment can happen any time before expiry, not only on the expiry date, so the collateral needs to stay in place for as long as the position is open. This is exactly why covered strategies keep the outcome predictable even with early assignment risk.

Q: What's the main risk difference between buying options and selling (short) options?
Buying an option caps your maximum loss at the premium you paid, while selling (shorting) an option can expose you to much larger losses if the market moves against you — theoretically unlimited for an uncovered short call. A covered strategy narrows that gap for sellers by pairing the short position with matching collateral, so losses on the option are offset by the value of the shares or cash held. Buyers never need collateral; sellers using a covered strategy effectively trade unlimited risk for a capped, measurable one.

Q: Do I need to already own the underlying stock to sell a covered call?
Yes. A covered call specifically requires you to hold the underlying shares as collateral before or when you sell the call — that's what makes it "covered" rather than naked. If you don't own the shares, Pluang's system will not let you open a Short Call position, since the platform requires every Short Options trade to be backed by adequate collateral. If you'd rather sell a put without owning shares, a cash-secured put is the covered alternative, using cash as collateral instead of stock.
