Some stocks are best avoided. It hits us in the gut when we see fellow investors suffer a loss. Imagine if you held Mallinckrodt plc (NYSE:MNK) for half a decade as the share price tanked 74%. On top of that, the share price has dropped a further 17% in a month.
There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.
In the last half decade Mallinckrodt saw its share price fall as its EPS declined below zero. This was, in part, due to extraordinary items impacting earnings. Since the company has fallen to a loss making position, it's hard to compare the change in EPS with the share price change. But we would generally expect a lower price, given the situation.

A Different Perspective
It's nice to see that Mallinckrodt shareholders have received a total shareholder return of 39% over the last year. That certainly beats the loss of about 23% per year over the last half decade. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business.
