Harbor Capital Makes a Splash by Shedding 75% of Its StoneX Holdings

So, here’s the tea: Harbor Capital Advisors has just let go of a whopping 270,715 shares of StoneX Group (SNEX 1.62%). Yes, you heard right – around $25.85 million worth of shares vanished quicker than my motivation to hit the gym come Monday morning.

What happened

According to the Securities and Exchange Commission (SEC) (because who doesn’t want the government peeking into their investment portfolio?), an October 15, 2025, filing revealed that our dear Harbor sold these shares in the third quarter. By the time the ink dried, Harbor had fewer than 100,000 shares left – about 93,877 shares more specifically, now worth a meager $9.47 million. The reality of investment can be as harsh as realizing you forgot your shopping list – what a buzzkill.

What else to know

Ah, the reduction of the StoneX Group position. Yes, it went from being 1.4% of Harbor’s 13F reportable assets under management (AUM) at the end of Q2 2025, to a paltry 0.74%. If you’re keeping score at home, that makes StoneX now the second smallest of Harbor’s holdings. Such is the rollercoaster of financial preferences.

Let’s dive into the juicy bits – Harbor Capital’s top holdings post-sale, as of September 30, 2025:

iShares Core S&P 500 ETF (IVV +0.29%): $49.15 million (3.82% of AUM)
iShares Msci Emerging Markets ETF (EEM 0.23%): $38.43 million (2.99% of AUM)
iShares Msci Eafe ETF (EFA 0.22%): $28.28 million (2.20% of AUM)
Nvidia (NVDA 0.20%): $27.22 million (2.12% of AUM)
Alphabet (GOOGL 0.10%): $26.54 million (2.06% of AUM)

No kidding, isn’t investment a performance art? As of October 14, 2025, StoneX Group shares were swanking about at $98.33, which is a staggering 70% higher than the previous year. That’s some fancy footwork compared to the S&P 500, which lagged by a mere 53.60 percentage points. Ouch.

Company Snapshot

Picture this: StoneX Group as a global financial services powerhouse with a dazzling array of offerings, connecting clients to markets like they’re matchmaking friends on a weekend. It’s all about access, execution, and risk management – you know, the core joys of financial life.

The company’s expertise allows it to slip clients gracefully into the global liquidity pool, like a well-prepared debutante. Its diversified business model and well-heeled capital markets presence are like the winning ticket in a lottery where everyone thought they had the right numbers, but only one person actually did.

StoneX provides everything from risk management and trading to physical commodity trading and global payments. They do it all, darling.
Revenue is made primarily through transaction-based fees, trading spreads, and clearing services – essentially, they charge for the privilege of playing in their financial playground.
Serving a varied clientele, from corporate giants to retail traders, it’s hard not to feel a tinge of excitement – like peeking behind the curtain at a particularly scandalous gala.

Foolish take

Now, let’s consider for a second what it means for Harbor Capital to have offloaded almost 75% of its SNEX holdings. All this left me wondering if they had cold feet or just fancied a round of financial spring cleaning. Harbor didn’t just dip their toes into the investment pool; they cannonballed in with roughly 30,000 shares in Q1 2024, subsequently amassing over 300,000 by the end of Q3 2024. And now it’s a fairy tale gone wrong, as they pare down significantly.

Interestingly enough, since they first bought in, the value of StoneX has nearly doubled. It’s as if they picked a winning lottery ticket only to decide halfway through the draw that they were maybe too good for the game. With solid growth and strategic acquisitions – like snagging R.J. O’Brien for a swing at the derivatives market – things looked sunny.

But now, with the investment managers reshuffling their portfolios like it’s a game of Tetris, one has to wonder: is this just a blow-out sale or a sign of something deeper? StoneX missed EPS estimates in their recent Q3 report, which might have made the stock’s momentum take a nosedive. Is it panic? Pride? A cunning poker face? The plot thickens.
