The "slowest tightening ever" followed by the fastest "welp, back to zero guys!" move once it comes to light that a: unemployment is a larger issue than reported, b: wages are crap, c: economically we're not as in good shape as thought.
I don't feel bad about being hugely in cash right now honestly. I've even reallocated 401k stuff around to more conservative holdings and I f I have to give up a *potential* 5-10% gain to avoid being a bag holding sucker ala 2000/2008, I'm content to do that. It's not like the broad market has been posting significant overall gains this year anyway.
