A vertical spread buys one option and sells another of the same type and expiration at a different strike — defining risk and reducing cost. It’s the building block of most options strategies (see vertical spreads explained).

How it works

Same type (both calls or both puts), same expiration, different strikes. You’re long one and short the other, so the position has defined risk and defined reward (the strike width caps both). It can be a debit (net pay, directional bet) or credit (net collect, decay bet). Cheaper and lower-risk than a single option in some contexts.

Why it's the foundation

Verticals are the components of bigger structures: two verticals make an iron condor or iron fly; a credit spread is a vertical. Understanding verticals unlocks nearly every multi-leg strategy. They’re how traders define risk and express directional or neutral views efficiently.

A vertical spread is two same-expiration options at different strikes — defined risk, defined reward, and the atom every complex strategy is built from.

The takeaway

Vertical spreads (long one strike, short another) define risk and are the foundation of options strategy. NoVo trades single long options rather than verticals (why), but understanding them is core options literacy. Compare with single options vs spreads for scalping.
