The stock did not move all weekend, yet your option lost value — that is Theta, the invisible hourglass over every option buyer. A full walkthrough of time decay.
Doing nothing at expiration is not just "the premium goes to zero": one cent in the money triggers auto-exercise, and a $2 premium can turn into $10,000 of stock. Here is exactly what happens.
Keep your shares, keep the upside, and lock the crash risk out — buy insurance for your stock. How the protection works, what the premium costs, how to pick the strike, and when it is actually worth it.
Earnings hit, the stock rallied — and your call lost money. The problem is not direction: you overpaid for "it will move a lot" the moment you bought. IV and IV crush, explained.
The more panicked the market, the more option buyers lose and sellers win. A CSP is as simple as "placing a limit buy order and getting paid for it" — the mechanics, the two outcomes, and the best timing.
Sell puts while in cash, sell calls once assigned, return to cash when called away — collecting premium at every step. How the wheel turns, what fuels it, and which stocks should never ride it.
Short selling has unlimited loss, borrow fees, and margin calls. A long put bets on the downside with a small, capped stake — and earns more the harder the stock falls. Mechanics, breakeven, strike selection, and the traps.
The broker showed $2.00, you bought one contract, and $200 left your account — you did not mis-click. The ×100 multiplier is the cipher behind every options number: the rule, the history, three practical calculations, and two exceptions.
Facing a wall of strikes, beginners tap the cheapest — then watch the stock rise while the option dies. The three zones, Delta as win-rate intuition, breakeven math, and the buyer/seller mirror — condensed into a pre-order framework.
Your call was correct and the stock did rally — two weeks after your option expired. The DTE spectrum, the accelerating decay curve, the weekend and earnings traps, and a framework for matching time to your thesis.
Buying is only the first half — profit lands only when you close. Winners ride round trips back to zero; losers get held into worthlessness. Not a selection problem: an exit problem. Draw three lines before you enter.
Monday morning: 100 shares appear, cash disappears — not a blow-up, an assignment. The four-quadrant map, the real cost math, three post-assignment options, and the early-assignment risk even veterans miss.
