Can someone help me make sense of why a stock goes down even after positive news?

Case in point, one of mine is USAR. USA Rare Earth, Inc. Analysts price this at up to $15, but over yesterday and today, it fell to $9.66/share and after hours it has hit $9.31/share.

On 4/30 yesterday, they announced a securities purchase agreement with a new fundamental institutional investor to raise $75 million of equity capital via a private investment in public equity (“PIPE”). The Company intends to use the proceeds from the offering to fund capital expenditures for its magnet manufacturing facility in Stillwater, Oklahoma, as well as for working capital and operating expenses.

Also towards the end of March 2025, analysts expected a breakeven for the company in the near future, which was of course quite positive news since things have been getting up and running.

About a month ago, they announced the new CEO, William Robert Steele Jr who was the previous CFO for Mujin Corp (AI robotics) and Managing Director at Bank of America Securities. He has a few decades of experience.

This stock has hit the floor over the past couple of days even after the S&P, Dow and others have dipped considerably and gone back up. Why does this happen to stocks so randomly?
