Mario Gabelli Backs Watts Water Technologies (WTS) on Building Efficiency Trends

Watts Water Technologies Inc. (NYSE:WTS) is one of the best stocks to buy according to billionaire Mario Gabelli.

Watts Water Technologies Inc. (NYSE:WTS) is the 11th-largest holding for GAMCO Investors, and the fund’s 13F filings as of the end of Q4 2025 indicate it has reduced its position in the stock by around 3.5% versus last quarter, to 425,854 shares. That pales in comparison to the nearly 1 million shares it used to command in early 2020 and over 2 million in 2012, according to Insider Monkey’s database.

While the stake has gradually come down, the stock has performed strongly, rising 160% over the last 5 years, 36% in 2025, and 12% so far this year.

In mid-2025, Gabelli Funds had highlighted Watts Water Technologies Inc. (NYSE:WTS) as a strong player in the building-efficiency theme, along with Johnson Controls.

On a separate note, WTS’s CEO and President Robert J. Pagano Jr. sold 16,066 shares on Feb. 19, 2026, at prices of around $325-$330 per share, leading to total proceeds of roughly $5.26 million. While the sale reduced his stake by 7.8%, it appears to be a minor insider sale, as he still owns 191,202 shares of the company, as per the SEC filings.

On the market sentiment side, recent analyst commentary has been highly encouraging, especially following the company’s strong Q4 results. As per a February 13 report, Goldman Sachs raised the stock’s price target from $267 to $323 while maintaining a Neutral rating. Apart from the strong results, the firm noted that the company also provided a robust outlook for Q1 and FY26, supported by acquisitions, data center expansion, and continued repair/replacement demand.

On the same day, the analysts at Baird also raised the stock’s price target to $361 from $312 and maintained a Neutral rating despite a bright outlook.

Watts Water Technologies Inc. (NYSE:WTS) provides water technologies and solutions designed to promote safety, energy efficiency, and water conservation in commercial and residential buildings.

While we acknowledge the risk and potential of WTS as an investment, our conviction lies in the belief that some AI stocks hold greater promise for delivering higher returns and doing so within a shorter time frame.

The $250 Trillion AI Hype is Real. A few years from now, you’ll probably wish you’d bought this stock.

When Jeff Bezos said that one breakthrough technology would shape Amazon’s destiny, even Wall Street’s biggest analysts were caught off guard.

Fast forward a year and Amazon’s new CEO Andy Jassy described generative AI as a “once-in-a-lifetime” technology that is already being used across Amazon to reinvent customer experiences.

At the 8th Future Investment Initiative conference, Elon Musk predicted that by 2040 there would be at least 10 billion humanoid robots, with each priced between $20,000 and $25,000.

Do the math. According to Musk, this technology could be worth $250 trillion by 2040.

Put another way, that’s roughly equal to:

  • 175 Teslas
  • 107 Amazons
  • 140 Metas
  • 84 Googles
  • 65 Microsofts
  • And 55 Nvidias

And here’s the wild part — this $250 trillion wave isn’t tied to one company, but to an entire ecosystem of AI innovators set to reshape the global economy.

It’s a leap so massive, it could reshape how businesses, governments, and consumers operate worldwide.

Even if that $250 trillion figure sounds ambitious, major firms like PwC and McKinsey still see AI unlocking multi-trillion-dollar potential.

How could anything be worth that much?

The answer lies in a breakthrough so powerful it’s redefining how humanity works, learns, and creates.

And this breakthrough has already set off a frenzy among hedge funds and Wall Street’s top investors.

What most investors don’t realize is that one under-owned company holds the key to this $250 trillion revolution.

In fact, Verge argues this company’s supercheap AI technology should concern rivals.

Before I reveal the details, let’s talk about how some of the richest people on the planet are positioning themselves.

  • Bill Gates sees artificial intelligence as the “biggest technological advance in my lifetime,” more transformative than the internet or personal computer, capable of improving healthcare, education, and addressing climate change.
  • Larry Ellison — through Oracle, is spending billions on Nvidia chips and partnering with Cohere to embed generative AI across Oracle’s cloud and apps.
  • Warren Buffett — not known for tech hype — says this breakthrough could have a ‘hugely beneficial social impact.

When billionaires from Silicon Valley to Wall Street line up behind the same idea — you know it’s worth paying attention to.

Even as we admire what Tesla, Nvidia, Alphabet, and Microsoft have built, we believe an even greater opportunity lies elsewhere…

But the real story isn’t Nvidia — it’s a much smaller company quietly improving the critical technology that makes this entire revolution possible.

And judging by what I’m hearing from both Silicon Valley insiders and Wall Street veterans…
