Stock Beta?

Question

Does anybody know over what period the Stock Beta displayed on yahoo is calculated? Also, is it calculated based on daily returns or monthly returns? I searched the Capital IQ website, where this information comes from, but I could not find anything.

You can probably figure it out by comparing the chart with that of the S&P.  If a short period of volatility follows a relative calm, is the beta 1.1, 1.5, 2.5, etc. Watch CRDC and see when the beta begins to change.
