Hedging Strategies: Putting the Pieces Together
Own a stock and add one option, and you can reshape your risk — buy insurance, earn income, or cap both ends. Each choice trades something away.
You now know the building blocks — calls, puts, premiums, time value (lessons 36–37) — and the deep truth that every hedge trades something away (lesson 38). Now let’s combine a stock you own with a single option to reshape your risk on purpose. Three classic combinations cover most of what real investors do, and each answers a different wish: “protect me from a crash,” “pay me some income,” or “do both cheaply.” Hold the question: if you own a stock, what could adding one option do for you — and what would each version cost you in return?
Protective put: buying insurance on a stock you own
The first and most intuitive: a protective put. You own a stock and you buy a put (the right to sell at a strike, lesson 36) on it. If the stock crashes below the strike, your put gains value and offsets the loss — you can still “sell” at the strike, so your downside is capped. Meanwhile, if the stock rises, you just let the put expire and keep all the upside. Sound perfect? Remember lesson 37: the put costs a premium, and it decays. So a protective put is literal insurance — a known, recurring cost (the premium) to cap a big unknown loss — and like all insurance, paying for protection you don’t end up needing is the price of peace of mind. Downside capped, upside kept, minus the premium.
Own a stock at $100, buy a put struck at $90 for a $3 premium: • Stock crashes to $60 → your put lets you sell at $90; your loss is capped at ~$10 + the $3 premium, not $40. • Stock rises to $130 → you let the put expire; you keep the gain, out only the $3. • You bought insurance: the $3 premium is the cost of capping the crash.
Covered call: renting out your upside for income
The mirror move: a covered call. You own a stock and sell a call on it (you take the premium now, and if the buyer exercises, you’re obligated to sell your shares at the strike). This generates income — the premium is yours to keep immediately. The trade-off (there’s always one): you’ve capped your upside. If the stock soars above the strike, you must hand over your shares at that strike and miss the gains beyond it. So a covered call suits someone who wants income and is content to sell at the strike if the stock rises a lot — you’re essentially renting out your potential gains above the strike in exchange for cash today. Income now, upside capped.
Own a stock at $100, sell a call struck at $110 for a $3 premium: • You pocket $3 immediately, no matter what. • Stock stays at $105 → call expires, you keep the shares and the $3. • Stock soars to $140 → you must sell at $110; you gained $10 + $3 but missed the run to $140. You rented out that upside for the $3.
The collar: pay for protection by selling upside
Combine the two and you get a collar: on a stock you own, buy a protective put and sell a covered call at the same time. The clever part: the premium you receive from selling the call helps pay for the put you’re buying — sometimes entirely, making it a near “free” hedge in cash terms. What did you give up? You’ve boxed yourself in on both ends: the put caps your downside (good) and the call caps your upside (the cost). You’ll neither lose much nor gain much — you’ve traded away the extremes for a narrow, protected middle. The collar perfectly captures this module’s theme: there’s no free protection; the collar just pays for its insurance with upside instead of cash. Every hedge is a trade, and now you can see exactly what’s on each side of it. (Education on the structures — not advice to use any of them.)
Think of owning a house. A protective put is home insurance: you pay a premium so a disaster can’t wipe you out, and if nothing bad happens, the premium was just the cost of sleeping soundly. A covered call is renting out a room: you collect steady income, but you’ve given up the freedom to use that room however you want — if a famous guest would’ve paid a fortune, too bad, it’s rented. A collar is paying for your insurance with the rent money: the room you rented out covers the insurance premium, so protection costs you little cash — but now you’ve both insured the house and committed the room, capping your bad and good surprises. Every arrangement trades one freedom for another.
Matching the structure to the wish: 1. “Protect me from a crash, I’ll pay for it” → protective put: downside capped, upside kept, costs a premium. 2. “Pay me income, I’m fine selling if it jumps” → covered call: premium now, upside capped at the strike. 3. “Protect me cheaply, I don’t need the big upside” → collar: the sold call funds the bought put; both ends capped. 4. Each reshapes the same owned stock differently — and each gives up exactly what it must to get what you want.
