Put Option Definition: A Put Option is a financial contract giving the buyer the right (but not the obligation) to sell an underlying asset at a predetermined strike price before or on the expiration date — paying a premium for protection against price declines. Major historical events: 1987 Black Monday October 19 (S&P -22.6% single day) led to portfolio insurance via puts, 2008 financial crisis ($16.7T equity wealth destroyed; March 2009 SPX bottom), March 2020 COVID-19 crash (-34%). Major Michael Burry “Big Short” 2007-2008 used puts (and CDS) for subprime bet ($1B Scion profit). Major typical SPX puts most-traded protective hedges; VIX measures put pricing.
What Is a Put Option?
A Put Option represents one of derivatives’ most consequential instruments, fundamentally enabling profit from declining prices or portfolio protection. Where calls bet on rallies, puts bet on declines. The framework affects markets through: hedging (portfolio managers protect), speculation (bearish bets), tail risk insurance, employee compensation (less common), and crisis pricing (VIX spikes). Major characteristics include: right not obligation to sell, strike price determines floor, expiration date, premium paid, theta decay, and theoretically maximum gain at strike-price-to-zero distance. Sophisticated participants understand puts central. Major institutional flows.

- Select strike price — ITM, ATM, OTM.
- Select expiration — weekly, monthly, LEAPS.
- Pay premium — intrinsic + time value.
- Exercise or sell — before expiration.
Worked example: Major put option examples demonstrate dynamics. Tesla TSLA put: TSLA trading $250. Major buy 1 put $240 strike, 30 days expiration, premium $5 (×100 shares = $500 cost). Major if TSLA falls to $220 by expiration: put worth $20 intrinsic = $2,000 contract. Major profit $1,500 (300% return on $500). Major Major protective put example: investor owns 100 AAPL at $220. Major buy 1 put $210 strike, premium $3 (= $300 cost). Major if AAPL crashes to $150: put worth $60 intrinsic = $6,000. Major Major historic: 1987 Black Monday October 19, 1987 S&P -22.6%. Major portfolio insurance (puts) blamed. Major Major 2008 financial crisis: S&P -38% year. Major March 2009 bottom. Major puts massive returns.
