Hey guys, I am trying to learn about stock markets & basic terminology. Sensex, Nifty, S & P 500 are all stock indices, but what do these actually mean and what do they measure?
They are a measure of market sentiment. They try to show the general feeling of investors for a category rather than for a single company. This can be interesting when there is a divergence, such as S&P500 is going down on a certain day but Exxon is going up can be a bullish sign for Exxon.
