Building Blocks of Options Strategies: Spread, Straddle, Collar, Strangle

Spread

refers to a strategy where you simultaneously buy and sell options of the same class (calls or puts) on the same underlying asset but with different strike prices or expiration dates. The structure caps both the loss and the gain. For example, a bull call spread involves buying a call option at a lower strike price while selling another call option at a higher strike price, both with the same expiration date. The spread reduces the initial cost compared to buying a single call option but also caps the maximum profit.

Straddle

Straddle strategies in finance involve executing two transactions on the same underlying security, where each transaction offsets the other. Investors use straddles when they expect a significant price movement but are uncertain about the direction—whether the price will rise or fall. In options trading, this strategy entails buying both a call and a put option at the same strike price and with the same expiration date. Example: Buy a call and a put option with a strike price of $100 expiring in September. You profit from a large move in either direction and your loss is capped at the two premiums — but you have bought the two most expensive options on the chain, so the move has to be substantial before you see anything.

Buy a straddle only when you believe realized volatility will exceed implied volatility — the number already embedded in the two premiums you are paying. “I expect a big move” is not a thesis; the market expects one too, and has charged you for it. The trade wins when the move is larger than the option chain priced, and loses when the move is merely large.

Strangle

Involves buying a call and a put option with different strike prices but the same expiration date. Example: Buy a call option with a strike price of $105 and a put option with a strike price of $95, both expiring in October. Cheaper than a straddle to put on, and correspondingly more likely to expire with both legs worthless.

Prefer a strangle to a straddle when you want the same directional agnosticism for less cash outlay, and accept in exchange that the underlying must travel further before you make anything. The lower premium is not a discount — it is the market charging you less because it is handing you less. Both legs start out-of-the-money — struck where exercising would not yet pay, a term made precise in the moneyness section below — so both can expire worthless on a move that would have paid off a straddle.

Straddles and strangles are similar strategies, but with a key difference: a straddle involves buying a call and a put option at the same strike price, while a strangle involves buying them at different strike prices. This distinction matters for both sides of the trade. As you widen the strangle’s strikes further out-of-the-money, the probability of either leg finishing in the money falls, but the leverage on the surviving leg goes up — you pay less premium and, on the rare day the underlying moves enough, the payoff is highly convex. Useful for the buyer. For the option writer the trade inverts: selling a wider strangle raises the win rate (more contracts expire worthless) but collapses the premium collected per dollar of tail risk you absorbed. In a fat-tailed world that almost guarantees you eventually wear an outsized loss for what looked like pennies of income. Writing wide naked strangles is one of the most reliable ways for retail accounts to blow up; it is also one of the easiest trades for institutional market-makers to feed you.

Collar

Collars are financial strategies designed to protect gains in stocks you own while still allowing for some upside potential. To implement a collar, you must hold the underlying asset, buy a protective put option, and sell a covered call option.

Example: Suppose you own 100 shares of XYZ. You would buy a put option with a strike price of $95 and sell a call option with a strike price of $105. This strategy hedges the share price by establishing a floor through the put option, which allows you to keep the stock but sell it if the price falls below the strike price. However, purchasing the put option requires paying a premium. To offset this cost, you sell a call option, granting another investor the right to buy the stock if its price rises. The trade-off is that this strategy caps any upside potential above the call option’s strike price.

Leland’s analysis of portfolio insurance¹³⁵ is the right frame for deciding whether to bother: buying downside protection makes sense for investors whose tolerance for risk rises with wealth faster than the market’s average, which describes most people carrying a position they cannot afford to see halved. It is a statement about who should buy protection, not a claim that protection comes without cost.

Every strategy in the catalog that follows is built from these four primitives, and every one of them is a trade about volatility wearing a directional costume. Before you place any of them, be able to say which side of the implied-versus-realized volatility question you are on and why the market is wrong. If you cannot, you are paying the bid-ask spread for the privilege of a complicated way to be long or short.
