Quote from weewilly:
These are risk-reversals and they are a very important tool in your toolbox. The negative skew in stocks/indexes is such that you can use this tool to capture yield in the event nothing happens. Splitting the strikes (selling otm puts/buying otm calls) can give you even more skew benefit. Of course you have to gauge your risk carefully, as always.
As an example, suppose you became bullish on AAPL, you might buy 100 sh of stock. Fine. Or, you might sell a 330P and buy a 330C for a credit, or sell a 320P and buy a 340C, also for a credit and a 10pt cushion to the downside. This is a bread-and-butter trade for options traders.
