Beta and correlation
In finance, the beta of a stock or portfolio is a number describing the relation of its returns with that of the financial market as a whole (in this case S&P500 Index).
An asset with a beta of 0 means that its price is not at all correlated with the market. A positive beta means that the asset generally follows the market. A negative beta shows that the asset inversely follows the market; the asset generally decreases in value if the market goes up and vice versa.
Beta is a combination of volatility and correlation. For example, if one stock has low volatility and high correlation, and the other stock has low correlation and high volatility, beta can decide which is more "risky".
In the table you can explore Beta(calculated on the basis of last 30 trading days ) and correlation(calculated on the basis of last 50 trading days) each related with S&P500 Index.
Consider that I calculated Beta and correlation on different periods to highlight the related movement of the stock during the period.
I have plotted stocks charts with overlapping the S&P500 index (color red).
