It's the valuation that matters. But we aren't talking about shares in the hundreds of dollars, but already bankruptcy discounted as low as 15 cents last year, and that was before the recent up turn in oil prices. Alot has changed since the quote you are providing. As oil and contracts increase so will the share price. And rightfully so. Looks like you missed the boat on the latest rise. But I still expect 1.00 per share very soon. Much sooner than originally thought. A rise above that will need much more increase in jobs for Seadrill, which will happen as long as oil prices remain above 70 dollars per barrel.
If one was to buy now, sell at a dollar still a pretty penny to be made over the next few months.
