Visualising 200 years of US Stock Market History

100 years ago no-one could have imagined what the stock market would look like today - it was heavily dominated by transport which barely features now.

That's the good thing about tracker funds - 
you are buying all of the market. No-one needs to predict new products or companies that don't exist yet or sectors that could grow to dominate the market.
