Cobra's Market View Private Messaging System shows:
Two tricks today, both point to a red day tomorrow or the next next trading day.
When ISEE Indices & ETFs Only Index > 100, 21 (red and blue arrows) out of 29 times (72%) there’ll be a close that closed below today’s close in 2 trading days.
When both SPX and VIX closed in green 10 (dashed red lines) out of 17 times (59%, a little short of my usual report threshold but since still some people are interested, so I list it here again.) a red day the next day.
The bottom line, I believe a half trading day tomorrow should generally be bullish but be careful after the Christmas, too many not so good signs have been accumulating, so at least not to chase high here.
