The ground rules of making money in the stock options market is to understand that
- Stock prices are random numbers. There may be a general pattern but it is ultimately just a roulette wheel. You never know what is going to happen.
- High risk comes with high reward while low risk comes with low reward. There is no free lunch and no suckers in the game. The market is efficient and nobody will pay a high reward for a low risk position.
- Uncertainty drives the options prices wildly. Whenever the underlying stock price is fluctuating violently, the options contract prices skyrocket, because nobody knows where the stock price will land. See first rule.
- You must choose companies that you know well, use their products (ideally) and know their business and how they make money. Don't invest in what you don't know.
What is theta?
Theta, in the context of Greek fundamentals as applied to options, is time decay. Options contract pricing is dependent on a few fundamental factors and Theta is a key part of it. The strategy that this screener is built on is to capture the time value of the options contracts that you would sell. As an option contract gets closer to its expiration, its theta value goes down, because there is less and less time for the stock price to change. That is all there is to it. All we want to do here is take a position that may be unlikely to happen and hope to capture the time decay as the option contract get closer to expiration, and ideally have the option contract expire worthless.
