What does "portfolio beta" mean, and how do I interpret it?

Beta measures how sensitive your portfolio is to movements in the overall market (typically the S&P 500):

  • Beta = 1.0 - your portfolio moves in line with the market.
  • Beta > 1.0 (e.g. 1.3) - more volatile than the market; tends to rise more in rallies and fall more in selloffs.
  • Beta < 1.0 (e.g. 0.7) - less volatile than the market; more defensive.
  • Beta near 0 - very low correlation with market movements (e.g. cash-heavy or alternative-heavy portfolios).

PortfolioPilot shows Market beta for each individual holding on the Details page. Your overall portfolio beta is a weighted average of your holdings' betas.

A higher beta generally means higher potential returns in bull markets but larger drawdowns in bear markets. Use it alongside your Portfolio Score to check whether your risk level matches your preference.
