The US stock market is expected to end 2025 with growth of more than 17%. For the third year in a row, investor enthusiasm for artificial intelligence is driving stock growth.

At the same time, companies involved in data storage and benefiting from big tech investments in AI have surged ahead in the past year, according to Bloomberg.
