This week’s wrap-up is packed with inflection points that are flying under the radar. We continue to dissect the clues that indicate a certain company’s five data center contract bids could materialize. Just one decent-sized contract could potentially double the size of the company. Another company’s blowout quarter sent shares up 20%, yet the stock is still cheap and investors have yet to associate the company with data center demand. We think the stock got lost in Friday’s weak market session.

During the June 2025 Open Forum, we rolled out a double feature: a new data center stock screen (launched May 20, tracking seven names) and something far more tangible—a boots-on-the-ground walkthrough of Tecogen Inc. (NYSE:TGEN) Boston headquarters and manufacturing floor. The in-person visit made a real impression.

Last weekend, I had the pleasure of sitting down with Mike, the author of the Multibagger Monitor Substack. He can also be found on X under the handle @Mike10947310. I wanted to take the time to share some of the most valuable takeaways from that chat, because it wasn’t just about stocks—it was about strategy, discipline, and how to build an edge in an underfollowed corner of the market where information is still incredibly inefficient.

I guarantee you that Warren Buffett would be buying this stock if he found it in the beginning of his career, starting from a small capital base. Key reasons why I like this stock: it’s a cash-generating machine, an under-the-radar leading manufacturer that just made a move giving it a huge competitive advantage, has executed large share repurchases at higher and higher prices, invested tens of millions of dollars in expansions, is rapidly growing earnings per share, and is still trading at dirt-cheap multiples.
