Commentary
In the last T2108 Update I warned that the S&P 500 (SPY) experienced a notable setback. The action on December 3, 2015, delivered definitive follow-through selling.

The S&P 500 (SPY) plunges through its 200DMA again on its way to a retest of 50DMA support.

Note that my trading call was not predicting the market’s reaction to the news of the day: the latest monetary policy decision from the European Central Bank (ECB). What I will call the Draghi Drubbing (the president of the ECB is Mario Draghi) simply provided a sufficient catalyst to trigger the follow-through selling. Think of the market being primed to throw a tantrum at even the slightest disappointment. The divergence I noted exposed the market’s true underlying weakness.
