Key Points:
- Calendar Spread Strategy: Buy long-term options and sell short-term options on the same event.
- Theta Decay: Profit from the difference in time decay between near-term and long-term contracts.
- Market Mispricing: Look for events where near-term options are overpriced compared to long-term options.
- Risk Management: This strategy is not risk-free; it requires careful analysis of market probabilities.
- Binary Options: Treat Polymarket as a platform for trading binary options rather than just gambling.
In-depth summary:
The article discusses a trading strategy on Polymarket that allows users to potentially earn $200 a day by leveraging time decay through a calendar spread. This strategy involves identifying the same event listed with different expiry dates and structuring a position that capitalizes on the differences in pricing between short-term and long-term options. The author emphasizes the importance of understanding how time decay works, noting that near-term options tend to decay faster than their long-term counterparts.
By selling the more expensive near-term options and buying the cheaper long-term options, traders can profit from the theta differential. For example, if a trader identifies a market for an event like “Bitcoin above $100k,” they might buy a June expiry option at 65 cents while selling a March expiry option at 60 cents. This setup allows them to benefit from the time decay of the March option while still holding the June option, which retains value longer.
However, the author cautions that this strategy is not without risks. It requires a nuanced understanding of market probabilities and the potential for mispricing. The key is to find situations where the market has overestimated the likelihood of an event occurring soon, allowing traders to profit from the relative value of the options involved. Overall, the article encourages readers to view Polymarket as a platform for trading binary options rather than simply a gambling site.
ELI5:
Imagine you have two tickets to a concert: one for this weekend and one for three months from now. If the concert is really popular, the ticket for this weekend might sell for a lot more than the one for three months later. You can sell the weekend ticket for a high price and buy the cheaper ticket for three months later. If the concert doesn’t sell out, you keep the money from the weekend ticket and still have the ticket for later!
