Is Premier Oil's share price being held back by a weak balance sheet?
In 2009, Morgan Stanley strategy analyst, Graham Secker, used the Z-score to rank a basket of European companies. He found that the companies with weaker balance sheets underperformed the market more than two-thirds of the time. Other studies have found similar results.
The takeaway? Screen out weak balance sheets.
One effective way to do this is to apply the Altman Z-Score, a checklist that was found to be up to 80-90% accurate in predicting bankruptcy one year before the event in the 31 years up until 1999 in the original study.
A Z-Score of more than 2.99 is considered to be a safe company, but a Z-Score of less than 1.8 points to a significant risk of financial distress within two years. We can see the checklist in action by applying it to a listed company. Take mid cap style neutral Premier Oil (LON:PMO), for example.
