Strangely, I detect that traders who depict themselves equally visual–i.e., they brand extensive purpose of nautical chart displays of prices together with indicators–are alongside those who merchandise with the to the lowest degree vision. They brand inferences from what they see; non from an agreement of what lies behind the displays.
Take VIX, the pop stair out of volatility implied past times options pricing, equally an example. We powerfulness brand inferences nigh whether stocks volition instruct upwards or downwards based upon VIX existence stretched to the upside or downside. What nosotros know, however, is that VIX tends to displace inversely with index price. VIX equally good tends to displace upwards or downwards with realized volatility. So when nosotros expression at a display of VIX, are nosotros genuinely seeing a reading of options-implied volatility or are nosotros seeing a conglomeration of several correlated variables?
To illustrate the point, I built a elementary model of VIX that eliminates the overlapping influence of previous cost elbow grease together with recent realized volatility. This adjusted VIX stair out captures the grade to which implied volatility is high or depression relative to what nosotros would expression based upon previous cost elbow grease together with realized volatility. A high adjusted VIX agency that options are pricing inwards to a greater extent than volatility than nosotros would usually expression from the recent cost movement; a depression adjusted VIX agency that options are pricing inwards less volatility that nosotros would usually expect.
I went dorsum to 2012 together with divided the adjusted VIX into quartiles. When the adjusted VIX was inwards its strongest quartile, the adjacent v days inwards SPY averaged a make of +.49%. When the adjusted VIX was inwards its weakest quartile, the adjacent v days inwards SPY averaged a make of +.72%. When the adjusted VIX was inwards its middle ii quartiles (i.e., when VIX was pretty much inwards business with what we’d expression from recent cost action), the adjacent v days inwards SPY averaged a loss of -.01%.
In other words, all the market’s gains since 2012 tin endure attributed to “mispricing” of VIX. But yous would never run into that inwards a elementary nautical chart of VIX.
Trading past times sight does non ever convey vision.
For those interested, the adjusted VIX is currently inwards its lowest quartile, understating the cost elbow grease we’ve seen recently.
