Ecovyst (NYSE:ECVT) Share Price Up 39% in the Last Year, Despite Negative Five-Year Annualised TSR

Ecovyst Inc. (NYSE:ECVT) has seen a 39% return in the last 1 year, outperforming the market return of 13%. The company's revenue growth of 25% may interest investors, but the shift from profitable to unprofitable over the last 12 months is a negative factor. The five-year annualized TSR loss of 3% per year also raises concerns.
