📚 Case Studies
1
Ford Motor Turnaround (1974)
During the 1973–74 bear market, Ford traded at a very low P/E as auto demand slumped. Neff bought heavily, believing earnings would normalize when recession and oil-shock fears eased.
✨ Outcome：Within several years, Ford rebounded sharply, delivering substantial gains and validating the low P/E contrarian bet.
2
General Electric Revaluation (1982)
Early 1980s recession fears pushed GE’s P/E below market averages despite solid cash flows and strong business franchises. Neff accumulated shares, expecting profit growth to resume with economic recovery.
✨ Outcome：As earnings and confidence improved through the 1980s, GE’s stock and valuation rose, producing significant outperformance.
