GLSI is currently priced at $19.38. Technicals currently rate "Strong Sell" while our fundamental analysis reads "Neutral". Notable factors include a robust Altman Z-Score, a weak Piotroski F-Score of 0/9, negative Return on Equity and a bullish Golden Cross on the moving averages. Valuation-wise, the stock is priced at a premium — multiples like P/E and EV/EBITDA sit above sector averages.
