Roughly 68% of outcomes should fall within this range under lognormal assumptions, though empirical markets have fatter tails.

BRO Strategy Sizing to the Expected Move

With Brown & Brown, Inc. pricing an expected move of 10.23% from $56.25, risk-defined strategies sized to the implied range structurally target the modal outcome distribution. Iron condors with wings at the ±1σ expected move boundaries collect premium against the ~68% probability that spot stays inside the range under lognormal assumptions; strangles set wider at ±1.5σ or ±2σ target the tails but pay smaller per-trade premium. Long-vol structures (long straddles, ratio backspreads) profit when realized move exceeds the implied move, the inverse trade: they bet against the lognormal assumption itself, capitalizing on the empirically fatter equity-return tails.

Frequently asked BRO expected move questions

What is the current BRO expected move?
As of May 15, 2026, Brown & Brown, Inc. (BRO) has an expected move of 10.23% over the next 34 days, implying a one-standard-deviation price range of $50.49 to $62.01 from the current $56.25. The expected move is derived from at-the-money straddle pricing and represents the market consensus for a ±1σ price move.
What does the BRO expected move mean for traders?
Roughly 68% of outcomes should fall within ±1 expected move and 95% within ±2 under lognormal assumptions, though equity returns have empirically fatter tails than log-normal predicts. Strategies sized to the expected move (iron condors at ±1σ, strangles at ±1.5σ) target the typical outcome distribution; strategies that profit from tail moves (long-vol structures, ratio backspreads) target the tails the lognormal model under-prices.
How is BRO expected move calculated?
The expected move displayed here is derived from at-the-money implied volatility scaled to the chosen tenor: expected move % is approximately ATM IV times sqrt(T / 365), where T is days to expiration. An equivalent straddle-based form: the ATM straddle (call + put at the same strike) is roughly sqrt(2/pi) times spot times IV times sqrt(T/365), so the implied one-standard-deviation move is approximately 1.25 times ATM straddle divided by spot. The two formulations agree once the sqrt(2/pi) constant is reconciled.
