Oscar Health’s CEO Just Bought $11.9 Million Worth of Stock. Here’s What Retail Investors Should Know.

April 8, 5:44 pm

Oscar Health (OSCR) CEO Mark Bertolini just made one of the more notable insider buys in the market.

On April 6, Bertolini bought 1,000,000 shares of Oscar Health at $11.92 per share, a purchase worth $11.92 million. The filing also showed a much larger conversion of performance stock units into common shares, along with shares withheld for taxes. But the part retail investors should focus on is simple: the CEO committed nearly $12 million to his own company.

Why This Trade Stands Out

Insider buying matters because executives know the business better than anyone else. They see internal trends, operating performance, and forward expectations before the market fully prices them in.

In Oscar’s case, the timing is interesting. Bertolini made the purchase with the stock trading close to its 52-week low. Oscar’s 52-week range is $10.69 to $23.80, and the shares closed at $12.76 on April 6. That means this was not a buy made after a big breakout. It was a sizable purchase made while sentiment around the stock was still fairly cautious.

Why He Might Have Bought

There are a few obvious reasons why Bertolini may have stepped in here.

First, Oscar is coming off a year of strong revenue growth. The company reported $11.7 billion in full-year 2025 revenue, up 28% year over year, and management is guiding for more than $18.7 billion in revenue in 2026.

Second, management is guiding for a major improvement in operating performance this year, with 2026 earnings from operations expected to land between $250 million and $450 million.

Third, insider buys of this size often signal confidence that the market is underestimating what comes next. If Bertolini believes Oscar is entering a stronger phase of growth, buying near the lows would make a lot of sense.

Why Retail Investors Should Pay Attention

This is exactly why following insider trades can be so powerful.

When a CEO buys millions of dollars’ worth of stock with personal capital, that is one of the clearest public signals investors can get. It does not guarantee the stock will go higher, but it can highlight conviction before the broader market fully catches on.

At AltIndex, we believe these signals matter. Retail investors rarely have access to management meetings or institutional research desks, but they can follow the money. Insider buying is one of the cleanest ways to see where confidence is building.

The Bottom Line

Oscar Health is still a stock that comes with risk, but a $11.92 million buy from the CEO is a signal worth taking seriously. Big insider purchases often show up before sentiment shifts, and that is exactly why smart investors track them closely.

AltIndex makes that easy. Our Insider Buying page is updated daily and highlights the latest meaningful insider purchases across the market, so retail investors can spot conviction early instead of chasing stocks after the crowd catches on.
