I understand my situation is an outlier, but my Roth IRA was not needed for retirement. I decided I could afford my Roth going to zero, which allowed me to take bigger risks (YMMV).
Three years ago Covid-19 fears caused a chunk of the stock market to be priced for bankruptcy. For each stock, maybe the price was accurate. But taken as a group, the chance of a fraction of the economy collapsing was mispriced. I studied it and decided "stocks recover", and bought a diverse group of stocks. If they all collapsed, we'd be talking about the second great depression right now. But they did recover, and my Roth IRA did extremely well.
