If you don’t subscribe to Barrons I highly recommend it.  And if you don’t I recommend reading Abelson and Santoli weekly at www.barrons.com where their articles are generally free. This week’s Abelson article is not only well written, articulate and thought provoking, but also very rational.   Have a look for yourself:

As Merrill Lynch’s David Rosenberg (who, incidentally, is planning to do a bit of adjusting himself and moving back to his native Canada; our loss, Canada’s gain) points out in a recent commentary, the official keepers of the books have been unusually aggressive in constructing seasonal adjustments for February’s economic data.

To illustrate, the seasonal adjustment for new-home sales was the strongest since 1982; for durable-goods orders, the strongest since they were first released in 1992; the retail-sales figures for February were flat (or, as David says, flattering) after such adjustment, but unadjusted fell 3%, the biggest drop on record. He also notes dryly that the 40,000 raw non-seasonally adjusted housing-start total for February “all of a sudden becomes a headline-adjusted annual rate figure of 583,000.”

Which makes David think that come the inevitably sharp downward revisions of such distorted data, first-quarter real GDP is likely to suffer a 7.2% drop. Which, together with the 6.3% skid in the fourth quarter of 2008, would be the worst back-to-back contraction in the economy in 50 years.
