To be fair i think times are rarely normal. Just since 2000 we've had the dot com bubble, great financial crisis, covid pandemic, ukraine war and now this. Although the current situation feels like a particularly unforced and unnecessary one. And before that there were also plenty of other crisis from world wars, the cold war with things like the cuban missile crisis or the 1973 oil crisis.
HYSA with those rates certainly seem like an appealing place to be in the current market, but as always this is a question about market timing, which is hard to impossible. When did you exit your positions and when do you plan to reenter? Because as said with the recent drops on a wide market scale we are still only down to levels just before the US election and nobody knows how things will play out in the future.
So my point still stands that anyone who is finding himself in acute issues due to the current market changes has done poor risk management. Broad market etfs are meant for a long term investment horizon of 10-15 years exactly so one can weather out downturns. And if someone is close to retirment it would have been prudent to shift some portion of savings into more stable investments similar to how target date funds handle it. Which might still be a good move right now, as the losses are still within reason, assuming a diversified investment strategy (and not something like having bought tesla at peak or the trump meme coin).
