Does Tullow Oil plc have too much debt?

Owain is a magpie of the investing world -- and not because he gets into a flap. Almost any style of investing might suit him, depending on the bigger picture, and he's held all sorts of companies. Paraphrasing Keynes, he says: “When the market changes, I change my mind -- what do you do?” That said, Owain is usually a buyer of equities, where he prefers lightly geared, modestly rated companies, and is increasingly on the lookout for Buffett-style intangible quality. He aspires to buy-and-hold: his best investment ideas are worth much more than he sold them for. Then again, his worst investment went bust due to management fraud!
