Buy-Write

Options

A buy-write is an options strategy where a trader buys shares of a stock and, at the same time, sells a call option against those shares. The call option gives someone else the right to buy the stock from the trader at a set price (the strike price) before a certain date. In exchange for taking on that obligation, the trader collects a cash payment upfront, called the premium.

The purpose of the trade is to generate income. If the stock stays below the strike price by the option's expiration, the option expires worthless, the trader keeps the shares, and the premium is pure profit on top of whatever the stock did. If the stock rises above the strike, the shares are typically "called away," meaning the trader is obligated to sell them at the strike price, capping the upside gain even if the stock kept climbing.

The nuance that trips people up is the tradeoff: a buy-write reduces risk slightly (the premium cushions a small drop in the stock) but it also caps the reward. It is not a way to own a stock "for free" or without risk — if the stock drops sharply, the trader still loses money on the shares, and the small premium collected barely offsets a large decline. Many brokers and exchanges package this as a single order ticket, which is why it's called "simultaneous," but mechanically it is just two positions — long stock and short call — opened together.

Buy-writes are also called "covered call" strategies when described from the options side, but "buy-write" specifically emphasizes that the stock purchase and the call sale happen as one coordinated trade, often to get a better combined price than executing the two legs separately.

Why it matters on the desk

Day traders sometimes use buy-writes intraday or overnight to generate quick premium income on a stock they already want to hold, but the capped upside means it's a poor choice if a trader actually expects a big, fast move.

An example

A trader buys 100 shares of a stock at $50 and simultaneously sells one call option with a $52 strike expiring in a week for a $0.60 premium. If the stock stays below $52, the trader keeps the shares and the $60 in premium (100 shares x $0.60). If the stock jumps to $55, the shares get called away at $52, so the trader misses the extra $3 per share of upside but still nets the gain to $52 plus the premium.
