Why Super Micro Computer, C3.ai, Taiwan Semiconductor, and Other Artificial Intelligence (AI) Stocks Rallied on Thursday

The drama of earnings season continued on Thursday as investors digested the latest financial reports and what they mean in terms of the ongoing economic recovery.

And while Arm’s results were better than expected, it was the company’s blockbuster forecast that caught market watchers by surprise.

While that might not seem spectacular at first glance, it blew past the company’s previous guidance in a range of $720 million and $800 million. Its profits also got a lift, with adjusted earnings per share (EPS) of $0.29 rising 32% year…
