How this works

The at-the-money straddle (ATM call + ATM put) for the nearest expiration is the market's quick estimate of the expected move by that date. A directional trade has to clear that move to beat what the premium already priced in.

The straddle sum slightly overstates a one-standard-deviation move; a common refinement multiplies it by roughly 0.85. Around earnings, the expected move is inflated by elevated implied volatility that collapses after the report (IV crush).
