### How to determine Beta?

Posted:

**Fri Sep 13, 2013 3:05 am**In finance, the beta (β) of a stock or portfolio is a number describing the correlated volatility of an asset in relation to the volatility of the benchmark that the asset is being compared to. Source : http://en.wikipedia.org/wiki/Beta_(finance)

Referring to above source, Beta value measures a stock's correlated volatility compared to the market as a whole, the volatility is measured by the standard deviation of historical prices, which essentially represents how much they fluctuate relative to the price average.

I would like to know to determine Beta, and to determine the Beta for A comparing with B.

Does anyone have any suggestions?

Thanks in advance for any suggestions :>
