How do you deploy your cash reserves?

On top of your DCA, how do you deploy your reserves? I see a lot of people in here say they have dry powder or will buy certain stocks at dips. While I know most people say just dca and forget it. For those who don't, what is your method? W.B. has been stock piling cash for years. T.N says dca but also save cash so you can double down on the major dips. But on the contrary Graham Stephen just made a video about how he's now just dca-ing without looking as well as diversifying more because anytime he tried to time the market he's mostly been wrong. Not trying to shed light on these people but what is your cash reserve strategy? Wait for it to go down x%? What percent is your threshold? I know there's a lot of value investors in here. Are you buying anything that's at a discount while your cash is available that week? Or are you waiting for the discount on the few stocks that you believe in?
