Thread regarding NCR (NCR)

I’ve put a lot of thought into the decision whether to buy NCR or not. On one hand the stock feels undervalued and smells like an opportunity, especially given the fact that the company is growing and that this whole industry is on a growing trend in the last couple of years.
My only, but most important concern is the instability in NCR stock. However I tend to think that the present rising momentum will be constant and that there will not be major ups and downs, given that the company looks more stable than ever. Any different opinions?
