Fox Corp's Dual-Class Share Spread Widens Near 90-Day High

The price spread between Fox Corp’s two classes of stock has widened to one of its highest levels in three months, creating a notable premium for the company's voting shares. As of August 28, 2026, the ratio between the price of Class A voting shares (FOXA) and Class B non-voting shares (FOX) stood at 1.120x, just shy of the 90-day high.

The Voting Premium

Fox Corp. maintains a dual-class share structure where both classes hold identical economic rights to the company's cash flows and dividends. The primary difference is governance: FOXA shares carry one vote each, while FOX shares have no voting rights. This distinction creates a persistent price gap, known as the "voting premium," which reflects the value the market assigns to having a say in corporate matters.

On Friday, FOXA shares were priced at $68.76 while FOX shares were at $61.37, representing a 12.0% premium for the voting stock. Over the past 90 days, this premium has fluctuated, with the price ratio ranging from a low of 1.096x to a high of 1.124x. The current level sits near the top of this recent range.

Market Implications

For arbitrageurs and quantitative traders, an elevated spread in economically equivalent assets can signal a potential pairs trading opportunity. The strategy involves shorting the relatively expensive asset (FOXA) while simultaneously buying the cheaper one (FOX), betting that the price ratio will revert to its historical average, which is approximately 1.112x over the last 90 days.

A convergence back to this mean would yield a profit for traders. However, the trade is not without risk, as a fundamental change in the company's governance or ownership could cause the premium to reprice permanently.

Key Risks and Considerations

Traders monitoring this spread face several key risks that could impact a mean-reversion strategy:

• Liquidity Disparity: FOXA shares are significantly more liquid, with an average daily trading volume of $6.63 million compared to just $1.73 million for FOX shares. This thin liquidity in the Class B shares can lead to higher transaction costs and slippage.
• Governance Events: Any developments related to the Murdoch family's control, potential mergers, or proposals to unify the share classes could permanently alter the voting premium, invalidating the basis for the trade.
• Index Rebalancing: Forced buying or selling pressure from index funds, should one share class be added or removed from a major index without the other, could also cause the spread to deviate from historical norms.
