Some are quite complicated. We have never found one that is foolproof, but many people would like to sell you a system, or get the commissions from your trading their respective systems. If you want information on strategies, find the CBOE and ask for information. What we don't do is recommend action. In quiet markets, selling covered calls against stocks you own can generate additional return.
Premiums change all the time.
Call premiums will get larger, and put premiums will get smaller. If you just know that the stock is about to turn around, puts are probably relatively cheap. As soon as the direction of the price changes, the put premiums will expand and call premiums will contract. The killer is that if prices go nowhere, the price of puts and the price of calls will both decline, because part of the price of an option is time value, and every day is another day closer to expiration, and that time value decreases. We don't have one for you.
