The AI sector is facing a market downturn, with Nvidia and Super Micro Computer stocks seeing sharp declines.

Super Micro's lack of earnings pre-announcement has caused investor unease, while Nvidia's decline may offer a purchase opportunity.

AI industry growth is projected at a 37% annual rate until 2030, potentially reaching a $2 trillion market value, indicating strong future prospects.

Intel, Apple, and Alphabet are favored for investment; Intel is revamping its business and introducing new AI GPUs, Apple is progressively enhancing AI capabilities, and Alphabet's robust brands position it well to promote its AI technologies.

Despite current market challenges, Intel, Apple, and Alphabet stocks are considered undervalued in April, presenting attractive investment options for long-term growth in the expanding AI market.
