What does “points” mean in such contexts (stock exchange, I believe)?
What does "points" mean In any stock market, there are certain stocks that go up and certain stocks that go down. Hence if we want to find the generic health of stock market, i.e. on an average is it going up or down, we have no means to find out.  A practise that has evolved over the years is take a set of companies and find if on average they have gone up or gone down. In very simple terms say in 1970 I take the Market Capitalization of a set of 50 companies, lets say its value is "X". I would now call this index as value of 100. Now after a month if the Market Capitalization is 2X, the index value would be 200. After another month if the Market Capitalization come down to 1.5X, then index value would be 150. So essentially now one is able to get the general trend more easily. S&P is an index of Select 500 companies based on various parameters. So in isolation 2000 does not mean anything. However as a comparison it does give quite a bit of insight. Note there are various adjustments made to factor, i.e. certain companies go bankrupt or are not doing well are removed from Index, share splits, mergers, etc. This ensure that the Index is neutral and does not show unwarranted spikes.
