In this article, we will look at Billionaire Mason Hawkins’ 10 Small-Cap Stocks with Huge Upside Potential.

Mason Hawkins’s Value Investment Strategy

Mason Hawkins is a prominent American investor, known for being the founder and chairman of Southeastern Asset Management. Hawkins holds a Bachelor of Arts in Finance from the University of Florida and later did his MBA in Finance from the University of Georgia. Before founding Southeastern Asset Management, the billionaire gained experience as a Director of Research at Atlantic National Bank and First Tennessee Investment Management. There he developed his value investment strategy and has since been known for his discipline in value investing. His fund Southeastern Asset Management also holds the same reputation, which can be witnessed through his concentrated portfolio of around 40 to 50 stocks. Southeastern Asset Management services 47 clients at the moment, with $5,271,901,660 as assets under management as of March 2024.

Value investment is an investment strategy that employs buying stocks of well-managed and quality companies at prices significantly below their intrinsic value. The core of Hawkins’ strategy is to purchase equities when their market price is no more than 60% of the firm’s appraisal of their intrinsic value. Value investors believe that the market overreacts to economic news, which leads to movement in stock prices, however, this news does not affect the long-term fundamentals of a company. Therefore, investors like Mason Hawkins do not follow the herd and use financial research and analysis to find quality companies. Value investors are also known for holding companies for a long term, but also actively ferret out stock that the market is underestimating.

Hawkins’ disciplined and research-based investment strategy has earned him widespread recognition. He achieved Investor’s Lifetime Achievement Award in 2005 and was also named Domestic Equity Fund Manager of the Year by Morningstar in 2006.

Under the current market condition, Hawkins’ value investment strategy has led Southeastern Asset Management’s attention towards small-cap stocks. While the small-cap stocks have largely underperformed the market when compared to their large-cap counterparts. However, according to Francis Gannon, Co-Chief Investment Officer at Royce Investment Partners, small-caps are attractively priced for long-term investment opportunities. Gannon’s investment advice aligns with Hawkins’s strategy, as he suggests investing in quality small-cap companies with strong fundamentals, low debt, established long-term earnings, and significant upside potential.

With that let’s take a look at the billionaire Mason Hawkins’ 10 small-cap stocks with huge upside potential.

Longleaf Partners Fund stated the following regarding HF Sinclair Corporation (NYSE:DINO) in its Q4 2024 investor letter:

“HF Sinclair Corporation (NYSE:DINO) – Energy infrastructure company HF Sinclair, which owns refining, midstream, specialty chemicals, marketing and renewable fuels assets, detracted in the quarter and for the year. The company owns unique assets that are protected from competition and has a great culture focused on value per share growth and realization. We had the opportunity to purchase this strong company in the quarter due to the recent refining downcycle and oil price volatility. We know HF Sinclair well having owned it before in 2015 in the Small-Cap Fund and having followed it since we first visited the company in 2009. As is typical in this industry, quarterly volatility in spread pricing can weigh on the share price in the short term, which is what happened this quarter. We were encouraged to see significant insider buying throughout the quarter as we were buying alongside them.”
