Shell looks to capitalise on BP's slide with potential bid

Any final decision will likely depend on whether BP stock continues to slide, the people said. Shares of BP have already lost nearly a third of their value in the last 12 months as a turnaround plan has fallen flat with investors and oil prices tumbled. Shell may also wait for BP to reach out or for another suitor to make a first move, and its current work could help it get prepared for such a scenario, some of the people said.
