The end of an earnings season can be a great time to discover new stocks and assess how companies are handling the current business environment. Let’s take a look at how TransDigm (NYSE: TDG) and the rest of the aerospace stocks fared in Q4.

Aerospace companies often possess technical expertise and have made significant capital investments to produce complex products. It is an industry where innovation is important, and lately, emissions and automation are in focus, so companies that boast advances in these areas can take market share. On the other hand, demand for aerospace products can ebb and flow with economic cycles and geopolitical tensions, which can be particularly painful for companies with high fixed costs.

The 14 aerospace stocks we track reported a satisfactory Q4. As a group, revenues beat analysts’ consensus estimates by 0.6% while next quarter’s revenue guidance was in line.

In light of this news, share prices of the companies have held steady as they are up 3.2% on average since the latest earnings results.
