Calendar Spread Basic Setup Question

More often than not you'll be better off selling the calendar, meaning you buy the near term and sell the far term when realized is low and the far term is overpriced.

Then you have theta and vega working against you, and the only way to profit is via gamma.

PS - the only way the back iv will be higher than the front iv is if there is an event, like earnings, in between the two expiries. And in that case, the back iv is likely to rise with each passing day, thus working against the cal.
 
In many cases when the front month is materially higher than the next month, there is likely an event before the first expiration. If you want to estimate your breakeven price movement, you need to estimate both IVOLS after the event and look to see where you breakeven at those expected IVOLs.

If there is an event that pushed the front IV so materially higher, I would most likely consider buying a strangle/straddle to take advantage of it especially if the price is relatively cheaper and hope that the infinite gamma takes over. LOL
 
...and hope that the infinite gamma takes over. LOL

Can you please explain to me, in simple terms, what infinite gamma means? To my virgin options ears, it sounds like free money. So help me understand infinite greeks.
