CSX Plummets 5% as Buffett Shuts Down Merger Hopes, Triggers Sector Turbulence

Summary
• CSX shares plunge 5.05% to $32.84, erasing $1.74 from its value in under 3 hours
• Buffett’s Omaha meeting with CSX CEO Hinrichs confirmed no bid for the railroad
• BNSF and CSX unveil coast-to-coast services, but merger speculation dies
• Ancora Holdings pressures CSX board to explore alternatives as pressure mounts

CSX’s dramatic intraday collapse reflects a market recalibration after Warren Buffett’s definitive rejection of a Berkshire Hathaway merger. With the stock trading near its 52-week low of $26.22, the railroad sector faces renewed scrutiny as investors weigh strategic options. The move underscores the fragility of merger-driven optimism in a sector already grappling with regulatory and operational headwinds.

Buffett’s Rejection Dashes Merger Hopes, Triggers Flight to Safety
Warren Buffett’s unequivocal dismissal of a Berkshire Hathaway railroad merger sent shockwaves through the market. The 91-year-old investor, known for his strategic acquisitions, met with CSX CEO Joseph Hinrichs in Omaha without advisors, leaving no room for speculation. This decision, confirmed by Berkshire representatives, dashed investor hopes of a $37.25+ valuation boost from a BNSF-CSX consolidation. The news coincided with BNSF and CSX’s announcement of new intermodal services, which, while strengthening connectivity, failed to offset the merger premium collapse. Ancora Holdings’ recent stake increase and calls for alternative partnerships further highlight the sector’s strategic uncertainty.

Rail Sector Volatility Intensifies as Union Pacific Also Retreats
The railroad sector’s broader malaise is evident as Union Pacific (UNP) declines 2.36%, mirroring CSX’s bearish momentum. While CSX’s drop is merger-specific, the sector’s collective retreat reflects macroeconomic concerns—rising interest rates, regulatory scrutiny, and decelerating freight demand. The Surface Transportation Board’s recent revenue adequacy rulings for CSX and UP underscore operational pressures, with investors now pricing in a more cautious outlook for capital-intensive rail operators.

Backtest CSX Stock Performance
The backtest of CSX's performance after a -5% intraday plunge shows favorable short-to-medium-term gains. The 3-Day win rate is 53.83%, the 10-Day win rate is 56.39%, and the 30-Day win rate is 59.80%, indicating a higher probability of positive returns in the immediate aftermath of the plunge. The maximum return during the backtest period was 2.39%, which occurred on day 59, suggesting that there is potential for recovery and even surpassing the previous price level.

Rail Sector at Inflection Point: Merge or Die
CSX’s 5% collapse signals a critical juncture for the railroad sector. With Buffett’s merger door closed and Ancora Holdings pushing for alternatives, the stock’s near-term path hinges on strategic clarity. The 200-day MA at $32.38 and 52-week low at $26.22 form a key battleground. Union Pacific’s -2.35% decline underscores sector-wide fragility. Investors should monitor CSX’s response to Ancora’s demands and watch for a breakdown below $32.38, which would validate a bearish technical setup. For now, CSX20250829C33 and NFRA offer the most dynamic plays in a sector teetering on the edge of transformation.
