Beta (β)

Definition: A mathematical coefficient measuring an asset's systematic volatility and sensitivity relative to the broader market index.

Comprehensive Institutional Breakdown

A beta of 1.0 indicates the security moves in tandem with the S&P 500. A beta of 1.5 indicates the asset is 50% more volatile than the market (surging 15% on a 10% market rise, but dropping 15% on a 10% decline). A beta below 1.0 denotes defensive, low-volatility characteristics.

Algorithmic Formula / Notation
β = Covariance(R_asset, R_market) ÷ Variance(R_market)
Institutional Scenario Example
High-growth tech equities and leveraged crypto tokens frequently exhibit betas between 1.6 and 2.5.
Cross-Market & Execution Note
High-beta assets require strictly smaller position sizing to stay under the 1.5% institutional risk cap.
