IMO, a mispriced option is when the premium for a particular strike is wide off of what it should be when compared with the other strikes of the same option.Can those terms be defined in anyway?
- What is a mis-priced option?
- What is a fair-priced option?

For example if the IV of a strike in the middle is bigger than that of its predecessor and successor, or is "out of order"; in that case also its price will be "out of order", ie mispriced.
One can find many such examples, I'll try to find one... Here's one:
Code:
MO (Altria Group Inc.) CurSpot=62.07 Puts-2016-Jul-15:

...
62.50 MO160715P00062500 2.79 2.55 2.86 -0.02 -0.71% 3 76 18.38%
65.00 MO160715P00065000 4.35 3.60 4.95 0.00 0.00% 20 20 22.40%

70.00 MO160715P00070000 14.75 6.70 10.70 0.00 0.00% 0 21 38.93%
...
Here, either the 65 strike or the 67.50 strike, or even both, is mispriced because its IV is "out of order".
And a fair priced one is when it is, obviously, not mispriced
. Also if IV=HV then it should be fair priced as well.But, I am sure some of the experts here can maybe give you a better answer...

And: You call yourself "OptionGuru" and don't know what a mispriced option is?...
