I am very bullish on AAPL and like to use options to catch its long term move (say, one year). However, the implied volatility is very high. If I do calls, it would be too expensive. If I do bullish call spreads, the upside move is limited. If I do diagnoal call spread, the near term premium is too little and would not offset the long premium meaningfully. What is the best bullish strategy under the high implied volatility?
