Fox Corp's two share classes are trading with a clear gap between them: Class A (FOXA) is quoted at $68.76 while Class B (FOX) is quoted at $61.37, producing an A/B price ratio of 1.120x, or a 12.0% voting premium, at the close on Aug 28, 2026. Over the prior 90-day window the ratio has moved between 1.096x on the low end and 1.124x on the high, placing the present spread near the range's upper boundary - a configuration that often signals a short-A / long-B stance for traders seeking mean reversion.
Structural setup
Economically, the two classes carry identical claims on Fox Corp cash flows: they receive the same dividends per share and represent the same underlying equity stake. The only structural distinction is voting power. Class A shares carry one vote per share, while Class B shares carry no voting rights. The persistent price differential therefore reflects the market's valuation of voting power - the so-called voting premium.
That premium coexists with near-identical fundamentals: both classes share a price-to-earnings multiple of 16.3x, a beta of 0.54, and together imply a company market capitalization of $26.76 billion. Those matched metrics make the pairing a textbook candidate for a pairs trade, where the core bet is that the spread between two economically equivalent instruments will revert toward historical norms.
How the spread has moved
Below is the 90-day evolution of the FOXA/FOX price ratio using market-close figures on the listed dates:
| Date | FOXA | FOX | FOXA/B Ratio |
|---|---|---|---|
| May 31 | $63.92 | $57.39 | 1.114x |
| Jun 15 | $54.76 | $49.95 | 1.096x ← low |
| Jun 29 | $50.39 | $45.71 | 1.102x |
| Jul 15 | $55.99 | $50.39 | 1.111x |
| Aug 7 | $64.03 | $57.03 | 1.123x |
| Aug 14 | $69.04 | $61.41 | 1.124x ← high |
| Aug 25 | $69.60 | $62.23 | 1.119x |
| Live | $68.76 | $61.37 | 1.120x |
During the most recent session FOXA moved +2.35% while FOX moved +1.71%, leaving the live ratio around 1.120x. The 90-day average sits at roughly 1.112x; trading at 1.120x places Class A about 0.7% above that recent mean - elevated, though not at an extreme.
Constructing a pairs trade
Market participants can approach the pair through a few common hedging frameworks:
- Dollar-neutral: Short $100,000 of FOXA and long $100,000 of FOX when the ratio exceeds the mean plus roughly one standard deviation (~1.12x). Because both classes carry the same beta (0.54), this structure is beta-neutral and is intended to profit if the ratio compresses back toward the mean.
- Ratio-neutral: Match share counts to equalize economic exposure. As an example, short approximately 893 shares of FOXA (about $61.4K) and long 1,000 shares of FOX (about $61.4K) to create a position that hedges the price ratio directly; the combined notional in that example is roughly $123K.
Traders often use explicit entry and exit cues tied to the ratio itself. A typical signal ladder described here is:
- Strong entry (short A / long B) when the ratio exceeds 1.12x - the spread is stretched and Class A is expensive relative to Class B.
- Heavier conviction if the ratio rises above 1.13x - historically rare and a strong reversion indicator.
- Take profit around 1.11x - the mean reversion target.
- Stop loss beyond 1.14x - viewed as a structural break if the voting premium is expanding rather than compressing.
- Reverse stance (long A / short B) only if the ratio falls below 1.10x - a scenario that has occurred, for example, during the June selloff.
Practical constraints: liquidity and dividends
Execution nuances are material. Average daily dollar volume differs markedly across the pair: FOXA trades about $6.63 million a day on average versus roughly $1.73 million for FOX, a liquidity gap of about 3.8x. That imbalance means slippage on the less-liquid leg (FOX) will erode returns if not managed with limit orders and conservative sizing. The thinner class also tends to gap more in stressed markets - during the June 15-23 selloff, for instance, the ratio briefly compressed to the 1.096x low as Class B sold off harder.
Dividend timing produces a modest carry effect: Class B yields 1.0% compared with Class A's 0.9%. In a short-A / long-B position that differential translates to a small net dividend collection, roughly 10 basis points annualized.
Risks that can break the trade
- Governance events - any actions tied to Murdoch family succession, charter amendments, or proposals to recapitalize the dual-class structure could permanently reprice the voting premium.
- Index reconstitution - if one share class is added to or removed from a major index independently of the other, forced flows from index funds could distort the spread.
- Short squeeze on the less-liquid class - a concentrated short position in Class B's thin float could spike its price, driving the ratio to extremes before reversion.
- Conversion arbitrage - if the share classes ever became convertible into one another, the spread would collapse to zero immediately.
Bottom line
At a 1.120x ratio, the Fox Corp dual-class spread sits near the upper end of its recent trading range but not at an extreme. A patient mean-reversion trader could consider a short FOXA / long FOX position here, targeting roughly 1.11x - equivalent to approximately 80 basis points of compression or about $0.60 per share on the current prices - with a stop near 1.14x. The structure is relatively clean from a fundamental standpoint given identical P/E, beta and market-cap metrics, but liquidity, dividend timing and especially governance catalysts remain the primary risks that can prevent the expected reversion.
