And that stocks fall by 50% or more roughly once every 35 to 40 years (4 times in the last 150 years).
Presumably that figure would be for the index. It's vastly more common for individual stocks.
On any given random day since 1986 (which includes several serious bull markets), on average 7.6% of mid-to-large caps are trading at less than half their 52 week highs. The percentage would be a fair bit higher considering all time highs, or small cap stocks.
In case anybody is interested, on average they are terrible investments. Average return negative, 13.5%/year worse than the S&P 500.
