Bryan Thomas Whalen Accurately Predicts Christmas Rally, Takes Heavy Positions in S&P 500 at Market Lows

The U.S. financial markets at the end of 2018 were engulfed in an atmosphere of rare pessimism. By mid-December, the S&P 500 had fallen to its lowest point of the year, marking its worst December performance since the Great Depression. Fund managers slashed exposure to risk assets, and cash allocations surged. Concerns over trade tensions, the Federal Reserve’s rate hikes, and a slowing global economy pushed market sentiment to what many described as a “bottomless mood.”

While most institutions chose to step aside or retreat, Bryan Thomas Whalen saw things differently. He believed the downturn was not the prelude to collapse, but rather a liquidity-driven overreaction. Speaking to his investment team in the Los Angeles office, he stated:“This is not the endgame—it’s a correction magnified by emotion. Before Christmas, the market will give us a clearer answer—and I’m betting on a rebound.”

Whalen’s conviction wasn’t based on impulse or a single signal. He noticed a softening tone from Federal Reserve officials, with Chair Jerome Powell noting in early December that rates were “just below neutral.” This suggested that fears over aggressive tightening might soon ease. Meanwhile, U.S. corporate profits remained strong, with S&P 500 third-quarter earnings growing over 25%, supported by ample cash flows and ongoing share buyback programs. To Whalen, what crushed the market wasn’t fundamentals, but technical imbalance—algorithmic trading and passive ETF sell-offs amplifying volatility.“When the market overreacts to bad news and ignores good news, that’s not a collapse in logic—it’s a dislocation in pricing,” he wrote in his investor report.

After December 17, Whalen began pushing for strategic re-entry during internal meetings. Instead of chasing speculative sectors, he focused on core undervalued assets within the S&P 500, particularly technology, healthcare, and industrial leaders. He emphasized that successful positioning was not about catching the bottom, but about standing at the intersection between panic and rational reversal. He reduced cash holdings from 22% to 8%, rotated capital into S&P 500 index futures and high-liquidity blue-chip stocks, and added long-term Treasuries for volatility hedging.

Some team members feared he was “buying too early,” but Whalen’s response was simple:“When the market returns to reason, you won’t get a second chance to get back in.”

His call proved prescient. Around Christmas, the market validated his thesis. On December 24, U.S. equities suffered their worst Christmas Eve selloff in history—only to stage a record-breaking rebound on December 26, with the S&P 500 surging more than 5% and the Dow Jones Industrial Average jumping nearly 1,100 points.Whalen sent his team a brief email that night: “At the end of emotional collapse begins the start of reason.” His portfolio rebounded over 9.4% in the final week of December, dramatically outperforming peers and benchmarks.

For Whalen, the rally was more than a profitable trade—it was a proof of principle. He continued to believe that the underlying logic of the U.S. economy remained intact: consumer spending was stable, corporate credit remained healthy, and unemployment held at a 3.7% low.“A country with record-low unemployment and record-high corporate profits doesn’t slip into recession because of a few rate hikes,” he wrote in his annual client letter. “Panic is temporary—but cash flow and earnings are enduring.”

In the final week of 2018, Whalen remained in the New York trading room, watching market screens flicker late into the night. He knew the year would be remembered in the asset management playbooks—not because of panic, but because someone chose to believe in value, data, and the market’s eventual return to reason.And that someone was the man who hit ‘buy’ on Christmas Eve.
