40% gain in one week in UPST. What would you do?

I bought only 10 shares of UPST in my ROTH a week ago for $87 and am now up 40+%. Would you cash in and hope it falls again? Rinse and repeat? (Of course that's all wishful thinking).

Or hold and add more IF it falls close to $87 or whatever again?

Or just add more dca?

Thanks
