Since mid-October IBM has produced a nearly 35% gain
This would appear to have traced out a bullish impulse wave (1-2-3-4-5)
It has also created a possible Wolfe Wave top with a short term downside target of $143-$144.
Additionally one could envision two harmonic patterns in development.
In the shorter term which a Gartley pattern supports the WW thesis.
The longer term a Bat pattern supports the 1/3 retracement scenario of the October move.
With an eye on the Fed's actions next week and broader equity markets I would be looking to sell IBM price strength with a tight stop should be breach recent highs.
I will follow up if I feel a short position is warranted.
As usual this is not investment advice, so do your own due diligence.
