Dividend options and futures

Between puts and calls

Assume a stock trades at S = $40, the difference P – C of a put to a call option with the same maturity and strike price is $3. Let the present value of the strike price be $41. Put-call parity would imply a present value for the dividend of:

PV(dividends) = P – C + S – PV(strike) = $3 + $40 – 41$ = $2

If an investor expects the company to pay $3 — in present value terms — instead of the $2 implied, he should borrow money, invest it in the stock and create a short synthetic futures by selling a call and buying a put on the underlying.

By owning the stock, the investor would profit from the higher dividend payment while being hedged by the options.
