What does "lapping someone's expectations" mean in?

Question

As a poorly rated one-star stock in the Motley Fool CAPS service, skeptics aren't convinced, despite the heady production that has found Baidu lapping Wall Street's expectations in four of its first five quarters as a public company.

Answer 1

I think it just means 'surpassing someone's expectations'.

I suppose 'lapping' is taken from athletics, where someone who runs much faster than the someone else 'laps' them, being one whole lap of the track ahead plus a few yards more.

In that case, "lapping someone's expectations" just means doing better than what someone expected a company to do, increasing its annual profits by a larger amount, etc.

Don't you just hate management jargon?
