Shorting IBM on weak fundamentals and appropriate wave structure

Yesterday the company published a mixed earnings report. It reported:
* earnings per share of $3.84 versus expected $3.78; that's a beat.
* revenue of $20.8 billion versus $20.95 billion, that's a miss, and the 13th consecutive quarterly decline.
The stock lost nearly 5% in the after hours. We are expecting more downside, as the wave count suggests the continuation of a longer-term downtrend. Stop-loss is a daily close above 170.
