Option Theta and the Effect of Time on Option Prices

Summary

This Portuguese-language lesson introduction defines option theta, also called time decay, as a measure of how an option's price is expected to change as time passes. It identifies implied volatility, time, and multi-leg option positions as related subjects in the section, indicating that the lesson series places theta within a broader treatment of option valuation and strategy structures.

The document lists five lessons with an approximate total duration of 27 minutes, but provides no lesson details, equations, examples, or evidence about theta's behavior across different options. It therefore serves as a brief course-section overview rather than a full explanation. Readers cannot infer from this text alone how theta is calculated, how it interacts with volatility or price movements, or how to manage time decay in a particular position.
