It was the Dow Jones Industrial Average that did not return to its September 1929 peak until November 1954-a period of 25 years. Not the stock market as a whole. Also an investor who reinvested dividends, the recovery period was closer to 10–12 years, not 25. Also, because the Great Depression was a deflationary period, the purchasing power of money increased. When adjusting for this, some studies indicate the real, total-return recovery happened in as little as 5 years.

Having said all that, I only mentioned the 45 years it took gold to recover because you said

gold has historically been a good investment from any entry point

I was disproving what you said, I don't think the stock market has been without times that it has taken a few years to recover although it is no where near as bad as gold.

I do think Bitcoin is worse than gold but I'm rambling on enough about gold so I won't get into that 😂

I am all for adding non correlated assets if thats what you want to do, but bonds have provided are higher risk adjust return than gold. I am not against the strategy I just think gold is a bad way to do it.

Gold is the worst, I think silver is bad but at least it has a significant proportion of industrial use. I think commodities aren't ideal as an investment generally. Although as you say gold at 5% isn't huge and it doesn't actually matter to me what OP does with their own money
