Why Rivian Stock Roared Ahead 10% on Friday

This morning, investment bank raised its price target on Rivian...to $15 a share.

Let me repeat that: Rivian stock closed at more than $16 last night. Mizuho just said it's only worth $15 (and gave the shares only a neutral rating -- not a buy). And investors responded by bidding Rivian stock up instead of down.
