VIX is one market indicator together with 11 indicators described in my book Profit from 2017 Market Crash.
described why the market would crash and why it would not. If it does
not crash this year, next year will be more dangerous and I have to
change the title to Profit from 2018 Market Crash until it crashes. The
market usually crashes once every four years and hence it is overdue.
Today the market is not sound fundamentally but sound technically.
