Calendarspread: A strategy employed by savvy investors to capitalize on time-based price differences in the same or similar financial assets. Investors will seek to buy cheaper options that expire further into the future, while at the same time, selling more expensive yet shorter-term options – thus forming a spread. By properly executing this approach, an investor can stand to gain profits when they’re able to forecast market fluctuations with accuracy. With patience and skill, a calendarspread has the potential to yield lucrative rewards for your portfolio.
