Today's options markets are very efficient and options tend to be "fairly priced" at all times.? As such, options are rarely, if ever, over or under priced.?
Option are, from time to time, relatively expensive or inexpensive.? However, just because an option is expensive does not mean that it is "over priced" as there may be a very good reason why the option price has increased.?

As we have all read in any prospectus or financial disclaimer, past performance is not an indication of future results.?
So, if you see IV rising or falling relative to historic volatility, it does not mean that the option is "over" or "under" priced.? Rather, it should prompt you to question why the market is pricing in a greater or lesser amount of future volatility.? Once you identify the catalyst for the IV change
, you can then determine whether you want to be long or short vega.?
