The easiest way to measure historical market performance is by relying on an index average even though they are bit flawed by survivorship bias. The idea is that you merely adjust your hypothetical portfolio based on index additions and subtractions.
That being said, until the last decade and a half stocks were a HORRIBLE investment for the period of the prior 70 years. To wit. In 1929 the Dow traded 380. It wasn't until 1955 that the pre crash high was broken. By the lows of 1974 the market was in the 500's. That means if you'd bought shitty in 1929 and puked on the lows in 1974 you made about 1% a year for your trouble. Likewise if you'd bought mid range in the mid 1960's (800 or so) you still didn't have a profit until post 1983.
The Nikkei made a high of 38,000 in 1989. Don't look for that one to be taken out anytime soon. NO investment is a sure thing because of past performance. And that goes for real estate, gold, cash, ect. That's not to say any of them won't be FABULOUS but it isn't BECAUSE of what they did before.
