Calix (CALX) is in focus after a wave of securities class action filings alleging the company misled investors about margins tied to advanced purchases of low cost memory components and subsequent negative margin pressures.

At a share price of $37.95, Calix has seen weaker momentum lately, with the 90 day share price return down 24.57% and the year to date share price return down 29.18%, while the 1 year total shareholder return is down 20.11% as investors weigh the class action headlines against ongoing customer wins for its cloud and AI platforms.
