My dual currency trade

Today I sold a contract of changing NZD to USD at the rate 0.5979 one month later for 32% pa returns on my capital. I analysed that in the short term, NZD will fall while USD will rise. I will remain in NZD if the stock market continues to fall. I feel that the current bull run is a rebound as there are no confirmed signals to convince a trend reversal. To hedge this movement, I'm considering to buy some blue chips, so that either way the market goes, I will maximise my gains.
