where to deploy capital in case there's a correction/crash?

Not financial advice. I am becoming increasingly convinced there will be some sort of 10-20% market-wide correct/crash in the upcoming weeks. QQQ banged its head against the wall at $630 >4 times since October - just like in the weeks that preceded the April 2025 tariffs crash. Q1 in a mid-term year is notoriously weak. I personally am keeping a lot of dry powder set aside for if/when this occurs. Any thoughts on what would be a slam dunk usage of cash for this potential event? Normally something in the mag 7 would be a "safe bet" though it seems like the market as a whole is rotating into more mid-cap names. Some potential thoughts: 1) sticking to the mag 7, something like $AMZN (debatable already at a discount) plus $GOOG(L) (in my opinion the strongest performing of the mag 7) 2) If getting out of the mag 7, $CAT and $VRT as two strong performers? 3) If looking at mid-cap index funds, index funds like $IWM and $MDY?
