Is there any conceivable way in which an OTM option's value will decrease or (will not move, for that matter) as the underlying moves in a direction that gets the option closer to the money, aside from decay attributed to time value?

If so do you know of any examples in which this has ever happened?

  • Volatility collapse. An example would be after earnings. May 9, 2016 at 19:26
  • what about for long term options of about a year which include 3 or 4 earning's dates, would they experience the same effect?

  • When demand is higher the risk gets higher, so the price goes higher. May 10, 2016 at 2:07
