Foolish take

Investment firm Informed Momentum's purchase of Primoris Services Corporation stock merits attention for a few reasons. The buy represented a new position in Primoris, and it was of such size that it catapulted Primoris to the fourth largest holding among the fund's 254 equities.

This action suggests Informed Momentum is bullish on Primoris stock even after shares rose this year, eventually hitting a 52-week high of $146.16 at the end of October. It's easy to see why.

Primoris is benefiting from the many infrastructure projects being undertaken to expand U.S. data center capacity to support artificial intelligence. In the third quarter, the company's revenue hit $2.2 billion, a whopping 32% year-over-year increase.

Given the AI industry is expected to see years of expansion, Primoris could continue to see sales growth for some time. This could be a key factor behind Informed Momentum's big buy, and is one reason why it's worth considering Primoris stock as an investment.
