We exited the position after two partnered late-stage (Phase 3) programs failed this summer, removing important opportunities underpinning our thesis.
As CRDO’s market capitalization grew, we began initiating a mid cap position in this stock we’ve owned in our small cap Fund for years.
We trimmed our position on the strength of the price move.
We initiated the position when indiscriminate selling in semiconductor and optical stocks pressured its share price.
We exited the position and used the proceeds to establish a new position in RBC Bearings, a designer and manufacturer of precision bearings and engineered components for the industrial, aerospace, and defense end markets.
