There is no 1929 Market Crash

Don't sell out of the stock market because of a fear of a repeat of the 1929 crash, dot.com crash or the 2008 recession -- or any other historical event happening again.
Since history is nonlinear, small differences between events can have widely different outcomes, so historical analogies are an uncertain guide to the future and can never prove anything.
Use analogical reasoning to begin an analysis, but always dig deeper into the underlying causes of the outcome of the past event before making an investment decision.
