Ok! VIX=Volatility of the S&P 100 Not NYSE and it’s keyed off the NDX so technically you are correct. Q1) but what does this mean? >>so the ratio of the implied volatility for each when compared to some third asset class is not going to give you the same signal. << My terminology was wrong but my question still stands Q2)If the $VIX is volatility of the S&P 100 why compare it to the NDX, “Nasd 100 / QQQ”? Granted, most of the S&P 100 companies are in the NDX, “Nasd 100 / QQQ”, but not all! Q3)Wouldn’t a truer measurement for the NDX, “Nasd 100 / QQQ” volatility be the $QQV? Q4)Unless you are wanting too see data that reaches back further than when the $QQV was created why use the $VIX to see the current volatility of the NDX, “NASD 100 / QQQ” when It is being influenced by Individual companies that are not in the top Nasd 100? They are giving 2 different signals. If I have miss stated something or if my understanding of something is wrong, correct me, but don’t get esoteric on me with, >>>“some third asset class”<<< generic, seemingly condescending comment…Come on, get technical on me :) :) :)
