Asked the same question in a facebook group (Options A to Z) i joined because i really liked some of his youtube content...anyway this was his reply I thought i would share with the group.
Hi Zack! Thank you for the kind words, and I'm glad you're finding the site helpful. Calendar spreads are primarily used for pricing discrepancies. For CLOV, the trade would be to buy December at 150% and sell June at 385%. However, that will make money assuming the stock stays fairly neutral--a big assumption with those stocks. So, you're right that it's statistically a good trade, but it's not a bullish outlook. Instead, there's a huge risk premium being offered by buyers of the June calls. They must bid up the price to entice sellers to take the other side of the trade. The big question is whether it's bid up too high, too low, or just right. I would take the trade, but keep deltas on the wings, For instance, you could sell the straddle but buy the wider-strike strangle with an added option on each wing. That way, you'll participate if the stock makes a big move--up or down--but also capitalize on the large pricing discrepancy.
