When billionaires or company insiders buy a stock, it’s rarely a shot in the dark. They have access to firsthand data, decades of market experience, and a front-row seat to their company’s performance, giving their trades an edge most investors don’t have. They know when fundamentals are strengthening, when valuations look too low, and when the market’s missing something big.
That’s why insider buying is one of the most closely watched signals on Wall Street. It doesn’t mean you should copy every move, but understanding what insiders are doing, and when, can uncover opportunities long before the rest of the market catches on.
In this guide, we’ll break down where to find billionaire and insider stock purchases, how to tell which ones matter, and how to use that data to make smarter, more confident investment decisions.

Why It’s Worth Tracking Billionaires & Company Insiders
Tracking billionaire and insider stock purchases helps investors spot high-conviction opportunities. It’s not at all surprising to learn that these individuals often have the best insights into a company’s future, so when they make a trade, it’s a big deal.
Insider buying shows that management and board members have real skin in the game. Like any investor, executives and directors tend to invest their personal money only in their own stock when they believe it is undervalued or poised for better days ahead.
For example, in early 2023, multiple Meta Platforms (META) insiders bought shares after the company saw a sharp selloff. The stock nearly doubled over the next year, a clear indication that they knew something “regular” investors did not.
Billionaire investors also offer valuable insights. Warren Buffett’s Berkshire Hathaway once revealed that it had built significant positions in Apple (AAPL) and Occidental Petroleum (OXY) through its 13F filings. These moves signaled high conviction that these stocks were underpriced and had a strong future ahead.

Who Are a Company’s Insiders?
Company insiders include executives (including C-suite members such as the CEO, CFO, COO, CTO, and CMO), members of the company’s Board of Directors, and any shareholders who own over 10% of the company.
These individuals are legally required to report their stock trades to the SEC because their actions can signal confidence (or concern) about a company’s future.
Since insiders and hedge fund managers are required to report their trades, we can track them using tools like TIKR and see what they’re buying.
Case Study: Snowflake Executives and Insider Buying
In mid-2024, Snowflake Inc. (SNOW) faced a challenging period with its stock declining from a high of $230/share to under $120/share.
Amid this downturn, former CEO Michael Speiser made a notable move by purchasing about $10 million in Snowflake shares, and current CEO Sridhar Ramaswamy acquired about $5 million in shares early in 2024.
These substantial insider purchases signaled strong confidence in the company’s future prospects.
Following these transactions, Snowflake’s stock reached a high of $226/share in June of 2025, and analysts still think the stock is undervalued today.

How to Track Billionaire & Insider Buys Using TIKR
Instead of digging through SEC filings or outdated spreadsheets, TIKR allows you to instantly see what top investors and insiders are buying, all in one place.
Track Billionaire Investors
On TIKR, tracking billionaire investors is easy.
You can search for famous hedge funds like Warren Buffett’s Berkshire Hathaway, David Tepper’s Appaloosa Management, and David Einhorn’s Greenlight Capital.
From there, you can see:
- Full international portfolio based on 13F filings (for US holdings) and international filings
- The stocks they’ve recently added, trimmed, or sold
- Portfolio weights
- Number of shares held
- Reported value of shares held
These are some of Berkshire Hathaway’s top holdings. It’s not shown on screen, but Berkshire has recently added to some of their Japanese holdings as well as their Constellation Brands and Domino’s Pizza positions.
If you’re not sure what hedge funds to track, TIKR breaks out some of the hedge funds by investing strategy, so you can find hedge fund managers that fit your investing style:
You can also click TIKR’s “Ownership” tab for any of these stocks to view which other top investors hold the stock.

Track a Stock’s Insider Ownership
To see the specific stock’s ownership, search for the company on TIKR, then go to the stock’s “Ownership” tab.
It’s usually best to filter top shareholders by hedge fund or individual investor so you can see who the top individuals are that own the stock.
On a stock’s Ownership tab, you’ll find:
- Top shareholders (Filtered by investor type)
- Whether they’ve been increasing or decreasing their stake over time
- Their total ownership as a percentage of shares outstanding
Shown below is Apple’s top shareholders, filtered by hedge funds and investment managers. Unsurprisingly, the big-name investment managers like Vanguard and State Street are Apple’s top shareholders, but you can also drill down to see Apple’s top individual shareholders and more:
TIKR’s Ownership tab provides a quick way to see which major investors and hedge funds hold a stock.
Track Insider Purchases
After searching for a company, you can view a company’s recent Insider Transactions to see if company executives, board members, or principal shareholders are buying or selling the stock.
You’ll see:
- A full list of recent insider purchases and sales
- The name and title of the insider
- The number of shares traded
- The date of the trade and the price executed
Below, you can see a handful of Apple’s insider transactions over the past few months. There’s been some selling, but that doesn’t necessarily mean Apple is a bad stock or it’s overvalued:
Lots of insider selling isn’t a good sign for a stock, so it’s best to check a stock’s recent Insider Transactions before you make a purchase.
Why Insider Buying Can Be a Catalyst
When insiders buy their own stock, it sends a clear message that they believe the stock is undervalued or has strong prospects ahead.
Insiders are the people who know the business best, such as the CEO, CFO, or board members, who see the company’s internal metrics, growth plans, and customer pipeline.
Unlike analysts or outside investors, they have the closest view of what’s really going on in the business.
That’s why insider buying can act as a short-term or long-term catalyst. In the short term, it can boost confidence and attract other investors.
In the long term, insider buying often signals a disconnect between the market’s perception of a business and the business’s reality, especially in beaten-down or overlooked stocks.
It’s not a perfect signal, but when insiders buy large amounts of stock, especially when several executives are buying at the same time, it’s often a sign that something important is happening.
Multiple Insider Buys
Additionally, it’s often a strong signal of internal conviction when multiple insiders are buying shares of their company around the same time.
For instance, when several executives at Lennar (LEN) bought shares during a housing pullback in 2022, the stock soon rebounded as mortgage sentiment stabilized.
Pro Tip: Combine Insider Buys with Valuation & Fundamentals
An insider’s conviction means more when the fundamentals support it, especially if a company trades at a low valuation, generates healthy cash flow, and if the stock trades well below analysts’ average price target.
As an example, in late 2023, Dollar General’s (DG) stock declined sharply on near-term operational challenges. At the same time, the company continued to generate free cash flow and trade at a discount to historical multiples.
Multiple insiders stepped in to buy the stock, and this drew attention from long-term investors.
