This may be the time for a reversal. From 2015's peak of 2135 to the subsequent low to 1810, the Fib extension of 161.8 puts the market top at 2335. We were just shy of that today.
The timing is potentially serendipitous for bears. On Tuesday and Wednesday Janet Yellen will speak to congress, and her tone will provide more context for the markets. We shall see.
