Suppose the problem is proving that they did it intentionally. And if they did, still doesn't explain how their profit is still so high up - unless they profited due to a ponzi as well. There are mining and construction stocks these days with horrendous FY14 performance but are making a steady recovery. Guess you can't take anything at face value.
Profit means little in the stock market (you can cook profit), learn to read the cash flow statement and most of your answers maybe lying there.
I dont have any holding in this business just general comments so I don't know their books but cash flow statement and free cash flow is a good figure to go by.
You can learn a bit from SGH saga where profit is growing at a healthy clip but have negative cash flow and once stuffed up and down comes the crash.
