Frequently Asked Questions
What does a beta of 2 mean?
A beta of 2 means the stock has historically moved twice as much as the overall market in the same direction. A beta above 1 signals higher volatility than the market; below 1 signals lower volatility.
How many return periods should I use?
This calculator uses four paired return periods for a simplified estimate. Professional analysts typically use 36 to 60 months of historical returns for a more statistically reliable beta.
