Even Warren Buffett has had to adapt.

Over the past 14 years, Berkshire Hathaway’s performance has kept pace with the S&P—but only by leaning heavily on one stock: Apple. At its peak, Apple made up 50% of Berkshire’s portfolio, outperforming the S&P by 12% annually. That outperformance masked underperformance elsewhere.

Now that two-thirds of the Apple position has been sold, Berkshire’s remaining Apple shares and cash are performing in line with the S&P. Net result? The portfolio is trending 6% below the S&P.

So what’s next?

To materially improve performance, Berkshire—and any investor—could look to a model-based strategy. Specifically, a gradual position in TQQQ, which mimics the top 50 fastest-growing stocks, offers a compelling path forward.

Here’s the math: every 2% allocation to TQQQ raises overall portfolio performance by about 1%. A 30% position would lift performance 8% above the S&P.

TQQQ is constantly evolving. It performs like the “next Apple”—not by betting on a single stock, but by systematically investing in momentum.
This is the future of investing. Model-based strategies like Stars and instruments like TQQQ give investors a way to stay ahead—without relying on finding the next unicorn stock.
