Looking at the chart, you can see that the VIX bottomed in early July just a hair above 10.0, a very low reading from a historical standpoint. As a point of reference, the last time the VIX was this low was in early 2007, just a few months before the markets peaked.
I want to point out a couple observations here. First, the VIX recently failed to re-test its low from July marking a higher low. This is a sign of strength, along with a positive MACD and rising RSI, that suggests a bit of nervousness in the broader markets. Second, and this is purely observational, but note how many "shooting stars" we've seen recently, as shown by the green arrows. Shooting star candlesticks, or long tails, tend to be bearish as the daily highs are unable to hold into the close. Just about every spike in the VIX for the last month has been sold aggressively. Very few (any?) days in the past month have seen the VIX close at or near the top of its daily range. It's almost as if the VIX is being managed to alleviate any perceptions of problems in the overall economy. I say that tongue-in-cheek because that's exactly what I think is happening.
I argued on July 27 that the markets were looking awfully toppy and the VIX really had nowhere to go but up. While only 6 weeks have gone by since that post, the markets have continued to flounder and the VIX is indeed strengthening. Continue to watch the VIX here as it is certainly suggesting weak markets ahead.
