I’ve been reading about red lights flashing for the stock market valuations

What percentage are you holding in cash relative to stocks/bonds? There’s a Case number and a Buffet number that the articles say are wildly high. I don’t know but am wondering if people are beefing up cash. These articles referenced the dot com and, even, the Great Depression - citing AI mania. Maybe my feed is just sending some alarmist baloney. Thoughts?
