bullish reversal on the S&P500?

Rarely do we see such a clean inverted head and shoulders pattern. And, in addition to confirming the break of the major trendline, prices seem to confirm the break of the 200-day moving average. Also, a golden cross should not be long in coming. However, it is necessary to wait for the break of the neckline before buying; this week (heavy in publication) seems ideal to do so in addition with volumes.
