The Warren Buffett Bank Strategy Shift: How BofA Lost Its Position as Berkshire's Favorite Financial Play

Warren Buffett’s relationship with banks has defined a significant portion of his investing career. Yet recent investment filings reveal a dramatic repositioning in how the legendary investor views major financial institutions. In the past year alone, Berkshire Hathaway has divested over 427 million shares of Bank of America—representing roughly 41% of the company’s once-massive stake. Simultaneously, Buffett has systematically increased his holdings in an industrial cyclical company whose returns have been nothing short of extraordinary. This dual strategy offers fascinating insights into how even the most successful investors must adapt their convictions in response to changing market conditions.

Berkshire’s Bank of America Exit: More Than Just Profit-Taking

At the midpoint of 2024, Bank of America represented Berkshire’s second-largest holding by market value. The company controlled over 1.03 billion BofA shares—a position Buffett had methodically built over years. Few investors understand financial institutions better than Buffett himself. He recognized early on that cyclical businesses like banks benefit disproportionately from extended economic expansions. During periods of sustained growth, financial institutions can expand loan portfolios and capitalize on favorable economic conditions far more effectively than during recessions.

However, the past four quarters have told a different story. The systematic reduction of Bank of America shares signals that Buffett’s calculus has shifted significantly. While profit-taking remains a plausible explanation, deeper factors are at work.

During Berkshire’s 2024 annual meeting, Buffett suggested he was trimming certain holdings to lock in gains at advantageous corporate tax rates—the same logic he applied to reducing Apple. Bank of America represents one of Berkshire’s substantial unrealized investment gains, making tax optimization a rational motivation.

Yet that explanation only captures part of the picture. Among major U.S. money-center banks, Bank of America stands most vulnerable to interest rate movements. When the Federal Reserve aggressively hiked rates from March 2022 through July 2023—adding 525 basis points—no large bank benefited more than BofA. Its net interest income surged as the bank enjoyed fatter lending margins.

The trajectory has reversed. The Federal Reserve is now firmly in an easing cycle, with recent cuts to the federal funds rate continuing the downward pressure. As rates decline, Bank of America’s earnings face disproportionate pressure relative to competitors. This rate sensitivity makes the stock less attractive in an environment moving toward lower borrowing costs.

Equally important is the valuation issue. Buffett is notoriously disciplined about prices paid. When he arranged an investment deal in August 2011, BofA common shares traded at a 68% discount to book value. Today, those same shares command a 39% premium. What was once a plain-as-day bargain has become expensive by historical standards. For an investor who built his fortune on buying at substantial discounts to intrinsic value, a 39% premium offers little appeal.

The Unlikely Hero: Why Buffett Is Building a Massive Position in a Cyclical Distributor

The most intriguing aspect of recent 13F filings isn’t the Bank of America exit—it’s what Berkshire is doing instead. Despite being a net seller of equities for 11 consecutive quarters to the tune of $177.4 billion, Buffett has consistently purchased shares of Pool Corp., a supplier of swimming pool equipment and maintenance products.

The buying pattern is unmistakable:

• Q3 2024: 404,057 shares purchased
• Q4 2024: 194,632 shares purchased
• Q1 2025: 865,311 shares purchased
• Q2 2025: 1,994,885 shares purchased

By the end of Q2 2025, Berkshire held 3,458,885 shares of Pool Corp. in total.

This sustained accumulation contradicts the broader cash-accumulation strategy Berkshire has pursued. For Buffett to keep buying the same stock across four consecutive quarters, while simultaneously divesting from nearly every other position, suggests unusually high conviction.

The logic mirrors his historical approach to industrial stocks and bank investments. Economic history shows that since World War II, the average U.S. recession has lasted approximately 10 months, while typical expansions stretch roughly five years. A business like Pool Corp., providing essential maintenance products for residential and commercial pools and spas, naturally spends significantly more time benefiting from economic strength than weathering downturns.

Pool’s business model provides another attraction Buffett prizes: recurring revenue streams. Once a homeowner or commercial operation installs a pool, ongoing maintenance supplies become mandatory. Chlorine, filters, pumps, repair parts—these items must be continuously purchased. The customer relationship becomes embedded in daily operations, creating predictable and recurring cash flows quarter after quarter.

Moreover, Pool Corp. is evolving its business beyond traditional wholesale distribution. The company’s Pool360 platform functions as an online marketplace while simultaneously serving as a software solution for professional pool technicians. This platform enables service professionals to market their businesses, optimize scheduling, and automate billing—essentially creating a network effect that strengthens customer relationships and expands margins.

Pool also maintains a disciplined capital return policy. The company regularly distributes cash through dividends and share repurchase programs. Since its IPO in mid-October 1995, Pool stock has surged more than 42,400% including reinvested dividends. That astronomical return demonstrates the power of compounding within a well-managed, recession-resistant business.

What This Shift Reveals About Buffett’s Current Investment Thesis

The divergence between Buffett’s actions on Bank of America versus Pool Corp. reveals an investor adapting his philosophy to current realities. He hasn’t abandoned his appreciation for financial institutions or cyclical businesses—he’s simply reallocating capital based on valuations, rate environments, and competitive positioning.

Bank of America remains relevant to understanding where financial stocks trade. Yet at 39% above book value with rate easing underway, the risk-reward has deteriorated. By contrast, Pool Corp. at current valuations apparently offers the kind of margin of safety that has always motivated Buffett’s acquisitions.

Buffett’s upcoming transition to Greg Abel’s leadership doesn’t diminish his active involvement in shaping Berkshire’s portfolio. These investment decisions represent his latest thinking on which sectors and companies best position shareholders for the next phase of the economic cycle.
