Options Trading

Buying or selling contracts that give the right — but not the obligation — to buy or sell an asset at a specific price before a set expiry date.

There are two basic option types: call options (the right to buy an asset at the strike price — you profit if the price rises above the strike) and put options (the right to sell at the strike price — you profit if the price falls below the strike). Options can be used to speculate (leveraged bets on price direction), hedge (protecting an existing position from adverse moves), or generate income (selling options to collect premiums).

The Greeks measure an option's sensitivity to various factors: Delta (how much the option price moves per $1 move in the underlying), Theta (time decay — options lose value every day as expiry approaches), Gamma (rate of delta change), and Vega (sensitivity to volatility changes). Most beginner options traders lose money because they underestimate Theta — buying options that expire worthless because the stock didn't move fast enough in the right direction. Options are not a beginner instrument.

An options contract is like a reservation, not a purchase. Imagine you want to buy a house listed at £300,000 but aren't sure yet. You pay the seller £5,000 to hold it at that price for 3 months. If prices rise and the house is worth £350,000, you exercise your option and buy at the reserved £300,000 — pocketing a £50,000 gain minus the £5,000 fee. If prices fall, you walk away and only lose the £5,000 reservation fee. That fee is the option premium.

Real world: In early 2021, some retail traders on Reddit's r/WallStreetBets bought call options on GameStop at strike prices far above the market price — what's called "out of the money" options. As GameStop's stock exploded from short squeeze pressure, those cheap options became extraordinarily valuable. A $500 investment in certain call options returned $50,000–$200,000+ in days. The flip side: the vast majority of options traders lose money, and many of those same traders lost everything on subsequent trades when the squeeze reversed.

💡 Options trading offers leveraged upside and defined downside for buyers — but time decay and complexity make them a tool that rewards deep understanding and punishes casual use.
