A strong rally on Friday more than erased losses from Thursday and left the market in much better shape. The chart below shows the S&P 500 ending the week back above its 200-day average after bouncing off its 50-day line on Thursday. Chartwatchers will now recognize the pattern of the last month as a “pennant” or “symmetrical triangle” which is defined by two converging trendlines. That’s usually a continuation pattern and increases the odds for an upside breakout. That would fit with the seasonal tendency for stocks to end the year on a high note.
