Third, the ratio does not take into account non-earnings factors, such as dividends or share buybacks, which can also impact the value of a stock or an index.

However, it should not be used as the sole basis for investment decisions, and investors should consider other factors such as earnings growth, quality of earnings, macroeconomic conditions, and non-earnings factors when making investment decisions.
