I have noticed this correlation between Nifty and Indiavix.
1. Whenever there is a spike in volatility and volume, that seems to mark the bottom for Nifty. 2. This theory seems to be holding for the last 7-8 months. 3. Currently, we are facing a similar kind of situation. The Vix has spiked and the price is tanking. 4. If the theory holds its value, the bottom may be reached soon. 5. However, this is just a probability like every other theory. Hence, we will have to wait and see it out.
