Fox Corp’s dual-class share structure has pushed the voting premium for Class A shares to a 90-day high as Class A (FOXA) traded at $68.76 and Class B (FOX) at $61.37 on Friday, yielding a 1.120x ratio that implies a 12% premium for voting rights.
The spread has widened from a 90-day average of 1.112x, with the latest gap approaching the cycle’s peak of 1.124x recorded on August 14. Historical data shows the ratio fluctuating between 1.096x in mid-June and the recent high, indicating a gradual re-pricing of voting power amid stable economic claims. Both share classes command identical market capitalizations of $26.76 billion, P/E ratios of 16.3x, and betas of 0.54, underscoring their economic equivalence despite the structural divide.
Liquidity remains heavily skewed toward FOXA, which recorded average daily dollar volume of $6.63 million compared with $1.73 million for FOX—a 3.8x disparity that traders cite as a factor in the persistent premium. Dividend yields also differ marginally, with FOX offering 1.0% versus 0.9% for FOXA, though the net effect from shorting FOXA and going long FOX nets roughly 10 basis points annually after accounting for the spread.
The current ratio sits above the mean plus one standard deviation threshold of 1.12x, a level historically associated with strong entry signals for dollar-neutral trades shorting FOXA and going long FOX. Profit targets are set near 1.11x, targeting approximately 80 basis points of convergence, while stop-loss levels are triggered if the ratio exceeds 1.14x. A reverse trade—long FOXA and short FOX—would be considered if the ratio falls below 1.10x, as occurred during the June selloff when FOXA dropped to $54.76 and FOX to $49.95.
Analysts note that governance events, such as succession plans within the Murdoch family or proposals to alter the dual-class structure, could disrupt the spread. Index reconstitutions or a short squeeze in the thinly traded FOX float also pose risks, while any conversion arbitrage—where the classes become interchangeable—would instantly collapse the premium to zero.
