NB Bancorp, Inc. (NBBK): Among Small-Cap Stocks Insiders Were Buying in Q1 2025

We recently published a list of 20 Small-Cap Stocks Insiders Were Buying in Q1 2025. In this article, we are going to take a look at where NB Bancorp, Inc. (NASDAQ:NBBK) stands against other small-cap stocks insiders were buying in Q1 2025.

President Donald Trump’s initial unilateral 10% tariff went into effect on Saturday, at least partly causing the drop in the stock market. On Sunday, the President said “I don’t want anything to go down, but sometimes you have to take medicine to fix something,” as reported by CNBC.

On Monday morning, the broader market index lost 1.87%, marking an 11% loss over the past five trading days, signaling the possibility of entering a bear market. Also, during Monday’s morning session, the blue-chip companies declined 2.34% and the NASDAQ Composite lost 1.57%.

Amid market uncertainty, insider trading often attracts attention. Executive stock purchases can indicate optimism, while sales might reflect personal financial decisions or investment diversification. Executives usually follow pre-arranged strategies, such as 10b5-1 plans, and insider trading should be considered alongside the company’s financial health and market conditions.

Our Methodology

Today, we’re focusing on stocks with small market capitalizations that have seen heavy insider buying activity in the first quarter of the year. Using Insider Monkey’s insider trading screener, we identified companies with market caps between $250 million and $2 billion, where at least four insiders purchased shares in the past three months. From this list, we ranked the top 20 stocks with the highest number of insiders making purchases. Stocks that have been recently covered were excluded from our analysis.

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 note the number of insiders who acquired shares in the first quarter and the market capitalizations. Let’s take a look at the 20 small-cap stocks insiders were buying in Q1 2025.

NB Bancorp ranks 20th among the small-cap stocks that insiders were buying in Q1 2025. This is a bank holding company for Needham Bank, offering a variety of banking products and services in the Greater Boston area. The Needham, Massachusetts-based company provides deposit accounts and commercial and residential loans, and invests in securities like U.S. treasuries, municipal bonds, and corporate bonds.

In January and March, four insiders, including the president and CEO, and CFO purchased around $802,943 worth of NB Bancorp shares at an average price of $18.47 per share. Over the past 12 months, the stock lost 12.42% and currently trades at $15.31 per share.

For the fourth quarter of 2024, the company reported net income of $15.6 million, or $0.40 per diluted share, compared to net income of $8.4 million, or $0.21 per diluted share, for the prior quarter. Operating net income, excluding one-time charges, amounted to $13.3 million, or $0.34 per diluted share, compared to operating net income of $13.1 million, or $0.33 per diluted share for the prior quarter.

One Wall Street analyst rates NB Bancorp stock as a “Moderate Buy” with a price target of $22.00. The price target suggests a 45.21% potential upside from the latest price.

Overall, NBBK ranks 20th on our list of small-cap stocks insiders were buying in Q1 2025. While we acknowledge the potential of NBBK, our conviction lies in the belief that AI stocks hold greater promise for delivering higher returns, and doing so within a shorter timeframe. There is an AI stock that went up since the beginning of 2025, while popular AI stocks lost around 25%.

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:

Wall Street calls this $3 stock a “Melting Ice Cube.” They said the same thing about BTI before it returned 90%.

My name is Inan Dogan. I’m the co-founder and Research Director of Insider Monkey. I have an important message for you today.

Since March 2017, my stock picks have returned 16.5% annually. Today, I’ve found an opportunity even bigger than my British American Tobacco call.

Two years ago, Wall Street wrote off British American Tobacco (BTI) as a “melting ice cube.” The stock had crashed 40% from its peak, and consensus said the business was dying.

We looked under the cover and realized they were wrong.

We alerted our subscribers, and BTI returned 90% in just 16 months.

Now if you had invested just $10,000 in BTI in June 2024, you’d be sitting on $19,000 in October 2025.

Today, we have identified a nearly identical pattern in a digital-first giant trading at $3.

While the market panics over a surface-level revenue decline, our PhD-led research shows management has actually surgically cut $100 million in waste to focus on high-margin growth.

This pattern is a hallmark of our 16.5% annual return track record. The current opportunity offers a 400% upside potential—dwarfing even our 90% BTI return.
