There are two ways to look at the profits reports that are emerging from corporate boardrooms, often after a brief stop for an added shine at the office of the firms’ accountants. One is to find out just how this or that firm has been doing in the past quarter, compared with a year ago and with analysts’ expectations. I leave that to security analysts, whose job it is to move from that information to a guess as to what it portends for the future, and from there to a “buy,” “sell,” or “hold” recommendation. With some 80 percent of companies thus far reporting exceeding analysts’ (modest) expectations, and their earnings increasing by 40 percent compared with last year, there is cheer in the counting houses.
