10 Stocks With The Most Insider Purchases In The Last Quarter

Page 1 of 9

In this article, we’ll take an in-depth look at the 10 stocks with the most insider purchases in the last quarter. Previously, we covered 10 stocks with at least $30 million in insider sales recently.

The trade war with China and fears of a recession are among the reasons U.S. stocks dropped on Monday. CBS News MoneyWatch correspondent Kelly O’Grady explained that at the core of the downward trend is uncertainty. “We do not know where tariffs are going, it’s changing by the minute, and investors hate uncertainty.”

On Monday, Beijing began implementing retaliatory tariffs on various U.S. farm products, for which China is the largest market. These include a 10% tax on soybeans, pork, beef, and fruit, and a 15% levy on chicken, wheat, and corn, according to CBS News.

Blue-chip companies fell 2.1%, while the broader market dropped 2.7%, hitting its lowest point this year. The NASDAQ dropped 4% after entering a correction last week.

Market analyst Adam Crisafulli from Vital Knowledge notes that the weakness stems from concerns about slowing growth, Trump’s pro-tariff agenda, and high valuations—factors that have been influencing sentiment since mid-February.

Goldman Sachs confirmed on Monday that it is downgrading its economic growth forecast for 2025 from 2.4% to 1.7%.

As the market adjusts to new political and economic shifts, some analysts remain optimistic, especially about AI technology’s potential. Insider trading often garners attention during these times, as executives have insights into their companies. For example, when a CEO or CFO purchases company stock, it can signal confidence in the business.

However, insider selling doesn’t always reflect a lack of confidence, as it could be for reasons like personal financial needs or portfolio adjustments. Executives often follow pre-arranged plans (10b5-1 plans) for these transactions.

Though insider activity can provide helpful signals, it should be viewed alongside broader factors like the company’s financial health, market conditions, and industry trends. Thorough research is essential for making informed investment choices.

Today, we’re focusing on the stocks with the most insider purchases in the last quarter. Using Insider Monkey’s insider trading screener, we identified stocks where at least five insiders bought shares in the last quarter (from Oct.1 to Dec. 31). From this group, we highlighted the 10 stocks with the highest number of individual purchases.

Our research has shown that we can outperform the market by imitating the top stock picks of the best hedge funds, focusing on insider trading and stock picks from hedge fund investor newsletters and conferences. Our quarterly newsletter’s strategy selects 14 small-cap and large-cap stocks every quarter and has returned 373.4% since May 2014, beating its benchmark by 218 percentage points (see more details here).

For each stock, we provide details on the number of insider purchases and the company’s current market capitalization. Let’s dive into the 10 stocks with the most insider purchases in the last quarter.

10. 374Water Inc. (NASDAQ:SCWO)

Number of insider purchases in the last quarter: 8

Market capitalization: $50.73 million

We begin the list with 374Water, a cleantech company that converts wet wastes into valuable resources in the U.S. The Durham, North Carolina-headquartered company processes materials such as sewage sludge, biosolids, food waste, hazardous and non-hazardous waste, and forever chemicals.

It provides AirSCWO systems, which use supercritical water oxidation to treat a range of waste streams. 374Water serves industries including agriculture, defense, oil and gas, waste management, environmental remediation, and municipal sectors.

On November 18, eight insiders, including the company’s president and CEO, and CFO, acquired $633,500 worth of 374Water shares at a price of $1.25 per share. The stock lost 27.21% since the beginning of the year and is now trading at $0.36 per share. Over the last 12 months, 374Water shares dropped 73.99%.

374Water is also among the 12 penny stocks with insider buying in 2025.

9. Flushing Financial Corporation (NASDAQ:FFIC)

Number of insider purchases in the last quarter: 9

Market capitalization: $438.59 million

Flushing Financial Corporation is the parent company of Flushing Bank, offering banking services to consumers, businesses, and government entities. The Uniondale, New York-headquartered firm provides various deposit accounts, including checking, savings, and CDs, as well as mortgage loans, small business loans, and consumer loans. The company operates full-service branches in New York and an online banking platform under the iGObanking and BankPurely brands.

On February 25, Flushing Financial’s board of directors declared a quarterly dividend on its common stock of $0.22 per common share.

On December 12, nine insiders purchased a total of around $248,468 worth of Flushing Financial shares at a price of $15.25 per share. The stock lost 8.47% year-to-date and is now trading at $13.07 per share. Over the last 12 months, Flushing Financial shares gained 1.08%.

According to four Wall Street analysts, Flushing Financial is a “Hold,” and its price target amounts to $17.00, writes TipRanks. The average price target suggests an upside of 30.77% from the latest price.

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…

This prediction might not be bold at all:

AI, Tariffs, Nuclear Power: One Undervalued Stock Connects ALL the Dots (Before It Explodes!)

Artificial intelligence is the greatest investment opportunity of our lifetime. The time to invest in groundbreaking AI is now, and this stock is a steal!

AI is eating the world—and the machines behind it are ravenous.

Each ChatGPT query, each model update, each robotic breakthrough consumes massive amounts of energy. In fact, AI is already pushing global power grids to the brink.

Wall Street is pouring hundreds of billions into artificial intelligence—training smarter chatbots, automating industries, and building the digital future. But there’s one urgent question few are asking:

Where will all of that energy come from?

AI is the most electricity-hungry technology ever invented. Each data center powering large language models like ChatGPT consumes as much energy as a small city. And it’s about to get worse.

Even Sam Altman, the founder of OpenAI, issued a stark warning:

“The future of AI depends on an energy breakthrough.”

Elon Musk was even more blunt:

“AI will run out of electricity by next year.”

As the world chases faster, smarter machines, a hidden crisis is emerging behind the scenes. Power grids are strained. Electricity prices are rising. Utilities are scrambling to expand capacity.

And that’s where the real opportunity lies…

One little-known company—almost entirely overlooked by most AI investors—could be the ultimate backdoor play. It’s not a chipmaker. It’s not a cloud platform. But it might be the most important AI stock in the US owns critical energy infrastructure assets positioned to feed the coming AI energy spike.

As demand from AI data centers explodes, this company is gearing up to profit from the most valuable commodity in the digital age: electricity.

The “Toll Booth” Operator of the AI Energy Boom

  • It owns critical nuclear energy infrastructure assets, positioning it at the heart of America’s next-generation power strategy.
  • It’s one of the only global companies capable of executing large-scale, complex EPC (engineering, procurement, and construction) projects across oil, gas, renewable fuels, and industrial infrastructure.
  • It plays a pivotal role in U.S. LNG exportation—a sector about to explode under President Trump’s renewed “America First” energy doctrine.

Trump has made it clear: Europe and U.S. allies must buy American LNG.

And our company sits in the toll booth—collecting fees on every drop exported.

But that’s not all…

As Trump’s proposed tariffs push American manufacturers to bring their operations back home, this company will be first in line to rebuild, retrofit, and reengineer those facilities.

AI. Energy. Tariffs. Onshoring. This One Company Ties It All Together.

While the world is distracted by flashy AI tickers, a few smart investors are quietly scooping up shares of the one company powering it all from behind the scenes.

AI needs energy. Energy needs infrastructure.

And infrastructure needs a builder with experience, scale, and execution.

This company has its finger in every pie—and Wall Street is just starting to notice.

Wall Street is noticing this company also because it is quietly riding all of these tailwinds—without the sky-high valuation.

While most energy and utility firms are buried under mountains of debt and coughing up hefty interest payments just to appease bondholders…

This company is completely debt-free.

In fact, it’s sitting on a war chest of cash—equal to nearly one-third of its entire market cap.

It also owns a huge equity stake in another red-hot AI play, giving investors indirect exposure to multiple AI growth engines without paying a premium.

And here’s what the smart money has started whispering…

The Hedge Fund Secret That’s Starting to Leak Out

This stock is so off-the-radar, so absurdly undervalued, that some of the most secretive hedge fund managers in the world have begun pitching it at closed-door investment summits.

They’re sharing it quietly, away from the cameras, to rooms full of ultra-wealthy clients.

Why? Because excluding cash and investments, this company is trading at less than 7 times earnings.

And that’s for a business tied to:

  • The AI infrastructure supercycle
  • The onshoring boom driven by Trump-era tariffs
  • A surge in U.S. LNG exports
  • And a unique footprint in nuclear energy—the future of clean, reliable power

You simply won’t find another AI and energy stock this cheap… with this much upside.

This isn’t a hype stock. It’s not riding on hope.

It’s delivering real cash flows, owns critical infrastructure, and holds stakes in other major growth stories.

This is your chance to get in before the rockets take off!

Disruption is the New Name of the Game: Let’s face it, complacency breeds stagnation.

AI is the ultimate disruptor, and it’s shaking the foundations of traditional industries.

The companies that embrace AI will thrive, while the dinosaurs clinging to outdated methods will be left in the dust.

As an investor, you want to be on the side of the winners, and AI is the winning ticket.

The Talent Pool is Overflowing: The world’s brightest minds are flocking to AI.

From computer scientists to mathematicians, the next generation of innovators is pouring its energy into this field.

This influx of talent guarantees a constant stream of groundbreaking ideas and rapid advancements.

By investing in AI, you’re essentially backing the future.

The future is powered by artificial intelligence, and the time to invest is NOW.
