Isn't this exactly why your investment portfolio needs to change with age? STONKS can only go up if you're 30 and don't plan to touch the money for 35 years, this is basically a fact(I'm just a SWE not a financial advisor). If you're 55 and looking to retire in the next decade you normally shift a larger portion of your assets into more stable investments.
