cclee,
My swing trade strategies depend on whether the current market environment is a trending market or a rangebound market. If the market is trending (for example the overall markets have been in a downtrend for the past several months), I will use basic chart reading TA to determine the course of action. In this continued downtrending market, for instance, I bought October 1400 NDX puts as the index broke down from its descending channel around Sept. 5.
In a rangebound market, rather than buy options I prefer to sell them as naked positions, taking advantage of time value erosion and the market's tendency to remain in a fixed range. For instance, if let's say an index is trading within a 200 point range, you could do a naked strangle by selling calls with a strike at the top end of the range and puts with a strike at the bottom of the range. That way, as long as the index remains in that 200 point range, at expiration you get to keep the entire amount of the premiums from selling the options. If the index breaks out to one side or the other, you can simply buy back that side of the options and let the other side ride.
While I've mentioned indexes here, the same strategies apply to stocks and sector indexes.
