Dividend Arbitrage
Dividend Arbitrage is an options strategy that seeks to profit from an upcoming dividend payment by purchasing in-the-money puts and the corresponding shares simultaneously, capturing the dividend while using the put to hedge downside risk and recover the stock's post-dividend price drop.
When a stock pays a dividend, the share price theoretically drops by the amount of the dividend on the ex-dividend date. This predictable price adjustment creates an opportunity for dividend arbitrage, particularly through the options market where the timing and magnitude of the dividend are already known.
The classic dividend arbitrage setup involves buying 100 shares of a stock just before its ex-dividend date and simultaneously buying a deep in-the-money put option with intrinsic value close to the current stock price. The deep ITM put gives the trader the right to sell the shares at the put strike. On ex-dividend date, the trader receives the dividend. The stock price drops by approximately the dividend amount, but the put option's value increases by a similar amount to offset the stock loss.
The profit comes from a mispricing between the dividend amount and the time value of the put option. If a deep ITM put has essentially zero extrinsic value (no time premium), the trader receives the full dividend while the put perfectly hedges the stock price decline. The net result is a risk-free cash extraction equal to the dividend, minus transaction costs.
However, true dividend arbitrage is extremely difficult in practice because options market makers price puts to reflect upcoming dividends. A deep ITM put will have its extrinsic value include an implied dividend adjustment, meaning the premium already accounts for the expected price drop. Arbitrageurs must find puts that are mispriced relative to the actual dividend to extract a profit.
Early exercise of deep ITM American-style puts is also a consideration. If the time value of a put is less than the carrying cost of holding the stock, rational options holders will exercise early to capture intrinsic value and redeploy capital. This dynamic limits the mispricing windows available for dividend arbitrage.
More sophisticated versions of dividend arbitrage involve exploiting differences between the implied dividend in the options market and the actual declared dividend, or differences in tax treatment between dividends received by different types of counterparties. Institutional traders with favorable tax treatment on dividends can extract value from dividend swaps and total return swaps that would not be available to taxable entities.
