The S&P 500’s Strangely Surprising Top Performers in September 2025

And so, as is often the case when a broad market index moves steadily upwards, there are always a few bold performers that steal the show. In September, we saw the usual suspects-companies that, with a little nudge here and there, manage to turn the world upside down. Enter stage left: Warner Brothers Discovery (WBD), AppLovin (APP), and Western Digital (WDC). Let’s take a quick wander through this odd little parade.

Tempus AI’s Stock Surge: A Close Look at the Numbers

The catalyst? A little good news from a recent acquisition: Ambry Genetics, the California-based genetic testing company Tempus picked up back in February. Ambry decided to drop a bombshell with its announcement this week: a major update to its cancer risk assessment platform, the CARE Program. This little tweak integrates breast density data into the Tyrer-Cuzick tool for more accurate breast cancer risk assessments. A move that could mean life or death, depending on which side of the betting table you’re sitting on.

Where Will Robinhood Stock Be in 3 Years?

The fintech superstar is a lot more than meme trades today. It serves a large and growing consumer base with an increasing array of services, and it has a lot more up its sleeve. But can it keep this up during the next three years? Let\’s see what might be happening at Robinhood in 2028.

Realty Income vs. Opendoor: A Comparative Analysis

Realty Income’s business model hinges on long-term tenant relationships and predictable cash flows. Its triple net lease structure transfers operational burdens to tenants, while its diversified tenant base mitigates concentration risk. The company’s historical resilience-maintaining occupancy rates above 96% since 1994-suggests a robust foundation. However, its reliance on recession-resistant retailers may limit growth in evolving market conditions.

Rate Cuts & REIT Redemption: A Portfolio Manager’s Guide

AGNC Investment (AGNC) is a mortgage REIT, which is to real estate as a spreadsheet is to a party. It doesn’t own houses; it owns mortgage-backed securities. Great if you enjoy watching spreadsheets sleep. Now, here’s the rub: High rates dry up mortgages like a drought in the Sahara. But falling rates? That’s the rainstorm everyone’s been waiting for. Suddenly, AGNC isn’t just a dusty ledger-it’s a kid with a piggy bank full of new investments. And since it borrows money to buy those mortgages (a practice I personally refer to as “leverage”), lower rates mean cheaper debt. That’s like getting a discount on your ex’s rent. The spread between what it earns and what it pays? That’s the margin you want to widen before the next coffee price hike.

OxyChem’s Exit: A Buffett Farce in Three Acts

Yet what of OxyChem, that chemical alchemist whose caustic soda and PVC pipes perfume the world? For $9.7 billion, Berkshire dons the mantle of savior, acquiring this “profitable” jewel. A sum not unlike the price of Lubrizol in 2011-ah, the sweet serendipity of repeating oneself! OxyChem’s “step-change in profitability,” they say, as if alchemy were a science and not a gamble dressed in spreadsheets.

Dividend Fortresses Amidst Political Storms

Two such entities emerge from the chaos: Tractor Supply (TSCO), custodian of rural America’s quiet resilience, and Kroger (KR), steward of the grocery cart’s sacred duty. One sells the tools of subsistence; the other, the sustenance itself. Together, they form a diadem of dependability in a world where even the moon might forget to rise.
