WMT is reporting earnings tomorrow morning before the market opening, and the press leading into the event is already prepping investors to expect a large price movement up. This particular earnings call will report for the period covering the Black Friday sales and after-Christmas clearance sales.
The chart is showing a strong inverted head and shoulders pattern that's almost perfect enough to print out for a textbook on recognizing chart patterns. RSI is still below the overbought zone and climing, and the MACD histogram and ADX/DMI indicators are rising bullish again after a short cooling off period in late January. Volume is clearly rising on price increases with only a minor increase in short interest just barely over 10% the daily average volume.
I'll be getting up early tomorrow to see how this security performs in the pre-market hours, and I plan to hop right on the bandwagon if what I see confirms today's theory.
