Every process need some time for the complete circle.Like wise the pump in Ethereum also need some time after the merge.It doesn't men,it will not occur at all.And when the price of bitcoin was back to old value,the ethereum value also back to 2000 dollars.Many people holding the ethereum from 2020,by believe of good pump in the ethereum after the merge of ether.So just hold your ethereum for some more months.
The merge actually bring hype on ETH, during this hype the market moves differently from other market and now that the hype on merge is over, it is natural for the market to join the current trend. Since ETH is overbought during the merge hype, it is natural for the ETH market to undergo correction. Correction plus the current bear market, it is normal for the price of ETH to drop. And it will drop until it is completely corrected.
Aside from that the transition from PoW to PoS also has effect on how the seller sells ETH. Since it is cheaper to gain ETH, it is also possible that sellers will compete for buyer making them adjust their selling price lower. Unless ETH developer comes up with a great solution in the effect of the transition, we might see ETH to drop more.
