Endemic weakness gradually spread across the markets today leaving M3 with an unusual ranking for tomorrow after XIV's mini-collapse.
Note that the Pairs charts below have both come down and crossed the zero line, completing a relatively short excursion into weakly bullish territory.
We're used to seeing either XIV,SSO,SPY or SPY,SSO,XIV ranjings, so SSO as an outlier reflects a situation of significant divergence between SPY and XIV.
Whether this anomaly is a byproduct of options expiration later this week or something more visceral remains to be seen.
