As the craze of earnings season draws to a close, here's a look back at some of the most exciting (and some less so) results from Q3. Today we are looking at the semiconductor manufacturing stocks, starting with Marvell Technology (NASDAQ:MRVL).

The semiconductor industry is driven by demand for advanced electronic products like smartphones, PCs, servers, and data storage. The need for technologies like artificial intelligence, 5G networks, and smart cars is also creating the next wave of growth for the industry. Keeping up with this dynamism requires new tools that can design, fabricate, and test chips at ever smaller sizes and more complex architectures, creating a dire need for semiconductor capital manufacturing equipment.

The 14 semiconductor manufacturing stocks we track reported a mixed Q3; on average, revenues beat analyst consensus estimates by 0.6% while next quarter's revenue guidance was 3.9% below consensus. Valuation multiples for growth stocks have reverted to their historical means after reaching highs in early 2021, but semiconductor manufacturing stocks held their ground better than others, with the share prices up 18.7% on average since the previous earnings results.
