Quarterly earnings results are a good time to check in on a company’s progress, especially compared to its peers in the same sector. Today we are looking at RBC Bearings (NYSE: RBC) and the best and worst performers in the engineered components and systems industry.

Engineered components and systems companies possess technical know-how in sometimes narrow areas such as metal forming or intelligent robotics. Lately, automation and connected equipment collecting analyzable data have been trending, creating new demand. On the other hand, like the broader industrials sector, engineered components and systems companies are at the whim of economic cycles.
