Not all after-market Friday releases are bad. BRK's quarterly earnings quadruple.
"Berkshire Hathaway Inc. News Release
Friday November 3, 4:54 pm ET "
"In the past we have always attempted to publish our periodic reports after a Friday close of the market. Our purpose has been to allow the public maximum time, while markets were closed, to scrutinize and evaluate our financial data. We continue to believe this to be the best schedule for disseminating important financial information. However, because the SEC has mandated that reporting times for both 10-Ks and 10-Qs be shortened, we may not be able to consistently hew to a weekend schedule in the future. That, nonetheless, will remain our goal."
