The shares may have taken great wit on Thursday and started on Friday. Nevertheless, the fear meter in the market has calmed down in the last few days.
The volatility index of the CBOE, also known as Vix, fell slightly to 24.03 on Friday. She retreated from climbing above 27 on Tuesday, which is the highest level so far this year. Usually every reading above 20 is considered vulnerable than usual.
Vix is a measure of how big the price changes are, either up or down. It is more difficult to increase when supplies fall. However, probably because supplies usually fall faster than they rise.
