Company Snapshot
AAON, Inc. manufactures and sells a diversified portfolio of commercial and industrial air conditioning and heating equipment, including rooftop units, chillers, air handling units, and data center cooling systems.
Primary customers include commercial clients in the retail, manufacturing, education, lodging, supermarket, data center, medical, and pharmaceutical sectors in the United States and Canada.
The company operates with an integrated manufacturing and sales model, generating revenue through the engineering, production, and direct sales of HVAC solutions. It leverages a network of independent representatives and an internal sales force.
Foolish take
When an investment firm dumps about $5 million in Nvidia stock and buys roughly $7.25 million in a commercial HVAC manufacturer instead, it's worth asking what's going on.
Jackson Square Partners has a very actively managed portfolio. In fact, of the 58 stock positions listed on its most recent 13F filing, not a single one remained unchanged during the quarter. The management team made far more sells (49) than buys (7). That suggests they may believe -- like many other analysts -- that the market is getting too frothy right now.
The fund's managers seemed especially bearish on semiconductor stocks this quarter. In addition to reducing their Nvidia position by 29,330 shares, they also made reductions to their holdings in chipmaker AMD, data center infrastructure company Vertiv, and semiconductor fabrication specialist ASML.
So why would a firm bearish on semiconductors and data centers increase its position in AAON, which has recently seen strong results driven by demand for data center cooling systems?
Well, unlike AMD, Vertiv, and ASML, which have all seen big year-to-date share price gains in 2025, AAON's shares are down 13.3% for the year, and they were down even further during Q3, when Jackson Square's purchases occurred.
This looks like a case of an investment firm that's worried about an overvalued stock market, so it moves money out of richly-valued stocks (perhaps doing some profit-taking in the process) and into stocks with more reasonable valuations.
