Assuming existing ownership of IBM stock. Using fibs, potential sell limit orders can be placed. The low sell limit has more odds. The highest sell limit could happen (you never know). The higher you go, the more chance you're taking it will reach that price at some point. Question is, how badly do you want to sell?
this stock seems to be cyclical, therefore could be considered for swing style trades.
based on fibonacci, and assuming ownership of some stock, this suggests Sell limit orders to set and forget.
