When most companies lower guidance, they issue a press release. American Commercial Lines (ACLI), a river barge operator, did just that on June 11, and its stock tumbled around 8%.
At the time the company said second quarter guidance would be about the same as the first. Enter this past weekend -- Saturday to be specific: American Commercial told analysts the second quarter would be less than the first. Note I said "told analysts" and not everybody.
The company's CFO sent an email to analysts without putting out a press release. What was he thinking? As you might guess, the analysts told their clients, which led to a 10% drop in the stock Monday. Everybody else had to wait until around 3 p.m. for the news to be released through an 8-K filing with the SEC saying that on June 16th the CFO disclosed what he disclosed without saying who he disclosed it to. Selective disclosure by any other name is...selective disclosure.
