Stock Market section poorly written[edit]

To me (a British native speaker) the penultimate two sentences in this paragraph don't make sense. —Preceding unsigned comment added by Robert.g.levy (talk • contribs) 14:14, 5 July 2010 (UTC)[reply]

I sympathize. This whole article is sketchy and stubby. The comments on cumulative abnormal return towards the end look at most only half right. You can see this from a simple bit of algebra, if you take compounding into account.

Actual abnormal return will not match so-called cumulative abnormal return, as defined here. That's my point.
