Krugman Errs Again

In his Sept. 30 column, Krugman writes of Bill Frist, “He sold all his stock in HCA, which his father helped found, just days before the stock plunged.” However, according to this AP story, Frist sold the shares on June 13 and the shares tumbled on July 13–about one month later. This timeline is corroborated in a news story from Krugman’s employer. A Krugman defender may argue that 30 days could count as “days.” But to me, anything in excess of six days no longer can be described as “days,” because after that point it becomes at least a week.
