Can anyone help me understand a seemingly dumb investment choice I made in light of this? I put some money into the Schwabs TIPS ETF (SCHP), back in December.

Can anyone help me understand a seemingly dumb investment choice I made in light of this? I put some money into the Schwabs TIPS ETF (SCHP), back in December. For the most part it's been a minor loser. Even today as the inflation rhetoric picks up the price is down 0.5%. Is it because people bought expecting inflation to be even higher? Or is there some lag or some underlying treasury thing going on.
