Yes, but the point is: even with the worst possible timing you still get ahead of inflation ($1.1M from $184k invested). With regular investments you could double the profits. Also, 1970-2015 period includes three big crises, with crashes of around 50% (1972, 2000, 2007), and a bit milder crash of 1987 (34%), calling it "quite a good one for stocks" is kind of a stretch.
