VIX, weekly.
Right now, only a VIX breaking under 17.00 would be cause for the bulls to feel confident, and to have real hope of SP' >1422.
Conversely, the doomer bears will desperately need to see a first stage attempt to hit VIX 24 in the days ahead. A pull back from 24 would be very natural, before the VIX might explode into the 30s/40s, especially as we move into the 'sell in May..go away' month.
The VIX weekly is certainly something to watch this week. Even if we do get a bounce in the main indexes across the next few days, the key issue will be how does the VIX close this week? A further weekly closing above the 10MA would be a serious warning of further falls in the indexes once we get opex out of the way.
Good wishes for Tuesday trading.
