Mildly bullish trading strategies are options that make money as long as the underlying asset price does not decrease to the strike price by the option's expiration date. These strategies may provide downside protection as well. Writing out-of-the-money covered calls is a good example of such a strategy. The purchaser of the covered call is paying a premium for the option to purchase, at the strike price (rather than the market price), the assets you already own. This is how traders hedge a stock that they own when it has gone against them for a period of time.
