I don't think he has doubled his position - he already owned around 9 million shares prior to this recent buying spree. At least he is bullish about the company's prospects - now all we need are some strong results, and to convince the investment community that this stock is worth buying.
Not sure however how long it will take for the coal market to pick up - it could be years before we see a positive quarterly net income from this company.
