Recall the following variables used in hedge analysis:
V0 The value of the portfolio of foreign assets at time 0, stated in the foreign currency.
Vt The value of the portfolio of foreign assets at time t, stated in the foreign currency.
Vt* - The value of the portfolio of foreign assets at time t, stated in the domestic currency.
St The spot rate, quoted at time t.
Ft The futures exchange rate, quoted at time t.
(Vt* - V0*) / V0* is the portfolio rate of return, stated in domestic currency terms. Vt
St - V0 S0 is the gain or loss on a portfolio, stated in domestic currency terms. V0
(-Ft + F0) is the gain or loss on a futures position, stated in domestic currency terms. Therefore, the net profit/loss, in domestic currency, is equal to (Vt
St
- V0 S0) (V0
(-Ft + F0)).
