Beta factor

Value of BetaInterpretationExample
β < 0Asset generally moves in the opposite direction as compared to the indexGold, which often moves opposite to the movements of the stock market
β = 0Movement of the asset is uncorrelated with the movement of the benchmarkFixed-yield asset, whose growth is unrelated to the movement of the stock market
0 < β < 1Movement of the asset is generally in the same direction as, but less than the movement of the benchmarkStable, "staple" stock such as a company that makes soap. Moves in the same direction as the market at large, but less susceptible to day-to-day fluctuation.
β = 1Movement of the asset is generally in the same direction as, and about the same amount as the movement of the benchmarkA representative stock, or a stock that is a strong contributor to the index itself.
β > 1Movement of the asset is generally in the same direction as, but more than the movement of the benchmarkVolatile stock, such as a tech stock, or stocks which are very strongly influenced by day-to-day market news.

This helps great in determining to play safe or play risky.

also , long term plays would be beta between 0 and 1

beta = 1 implies companies that show the overall index (AAPL = 0.93)
