Growth stocks are better than nongrowth stocks. Growth stock are companies with sales really going up (in reasonable profit margin or loss). If focusing in earnings growth only, then turnaround and cyclicals are mixed into the consideration. Cyclical factors are not reliable drivers of the long-term growths of a business.
A investment grade turnaround energy should be those that are free of bankruptcy risk in the next 18 to 24 months, or it has no investing value.
