ESS Tech, Inc. (GWH) is currently trading at $1.01. The stock presents a mixed profile: our models indicate a Buy for technical indicators, while underlying fundamentals flash a Sell. 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 and a bearish Death Cross on the long-term moving averages. On the valuation front, GWH trades at elevated multiples relative to its peers, earning a "Richly Valued" assessment.
