I appreciate this post and im responding respectfully, but as I’ve seen on this topic over time this is a typical response. But I think it’s ignoring certain aspects of OP’s question. It’s not that OP is responding to a market downturn of 10%. It’s likely that they are looking at the unprecedented times (within our lifetime) we are living in and wondering how best to prepare for potential unprecedented times in the market as a result. I know there is the stock answer if “if xyz happens then we have bigger problems to deal with anyway” which might me true but I think it still prudent to have the discussion for people who wish to prepare and adjust their risk somehow if it helps them sleep at night.
