The VIX is known as the 'fear index'. It has taken a pulse north which is not unexpected, as volatility on the P SPX500 took a leap recently.
The VIX is not an index I trade, nor do I know anyone who trades it. Its value is in keeping a finger on the 'pulse' of the stock market.
When the VIX begins to pulse, expect trouble. Some see trouble only after it has happened.
