ClearSign Technologies Corporation Common Stock (DE) (CLIR) trades at $3.94 per share. The stock presents a bearish profile across the board: technical indicators signal "Strong Sell" and our fundamental models agree with a "Sell" rating. This is driven by a concerning Altman Z-Score in the distress zone, a weak Piotroski F-Score of 1/9, negative Return on Equity, a bearish Death Cross on the long-term moving averages and bearish long-term moving average alignment. On valuation, CLIR trades roughly in line with sector averages — neither particularly cheap nor expensive.
