Options

An option is a contract for 100 shares of a stock. A call gives the buyer the right to buy at the strike price before expiration; a put gives the right to sell. The buyer pays a premium for the right without the obligation; the seller collects the premium and takes the obligation. The Options Clearing Corporation, the OCC, guarantees every contract's settlement, which is why counterparties never meet.

The premium has two parts: intrinsic value, what the contract would be worth if exercised now, and extrinsic value, the price of time and expected movement, which decays to zero by expiration. Contracts come in weekly and monthly expirations, American-style exercisable any time or European-style exercisable only at expiry. Retail brokers allow long options and cash-secured puts in IRAs; naked short calls are a taxable-account, margin-account activity, and FINRA requires a signed options agreement before the first trade.

The arithmetic of a long call: a $100 stock with a one-month $105 call priced at $2 costs $200 per contract. At expiration the contract is worth the stock price minus $105, if positive, and zero otherwise. The stock at $110 makes the contract worth $500, a $300 profit on $200, or 150%. The stock at $104 makes it worth $0, a 100% loss. The breakeven is $107, the strike plus the premium, and the stock must clear it before the deadline for anything to be kept.

The put is the mirror: a one-month $95 put at $2 pays if the stock closes below $95. The stock at $85 makes the contract worth $1,000, an $800 profit, and the put's whole pitch is that the loss is capped at the premium, $200, no matter how far the stock falls. This is why puts are described as insurance, and the premium is the insurance bill.

Time decay is the seller's edge and the buyer's tax. Extrinsic value decays every day, and the decay accelerates in an option's final weeks: a contract left out of the money loses its remaining premium fastest. Implied volatility moves the other input: premium rises with expected movement, so buying after a volatility spike means paying the panic price. Brokerage transaction studies consistently find the majority of retail option traders lose money, and the countdown is the mechanism.

Options are leverage with a deadline and insurance with a bill. Both descriptions are accurate, which is what makes them dangerous in careless hands. A $200 contract controls $10,000 of stock, so the percentage math is seductive; the same leverage means the premium can go to zero while the stock barely moves.

I watched a colleague named Brent (yes, that Brent) buy weekly calls on a crowded meme stock for eleven consecutive Fridays, $200 at a time. Each week felt like the week. Nine of the eleven expired worthless and two paid small, and the ledger read minus $2,200 for a stock that ended the quarter within 3% of where it started. The direction was right twice; the clock was wrong nine times.

The highest-leverage thing most Americans can do, if options at all, is start with the conservative end. Long puts work as portfolio insurance sized to the position, or cash-secured puts on stocks they would buy anyway. Skip naked short calls entirely.
