Zweig Breadth indicator hit oversold on Friday, 3 days too late for a thrust.. but still bullish $spx [chart]..

For an official Zweig thrust we need to move from oversold to overbought in a 10 day window.  That signal when it happens is a starting gun for a 12 month bull market..  Missing by 3 days does sustainably take away from the bullish predictability of the run, but it remains a bullish accomplishment  and overbought can remain so for a while.  Not a time to short.
