The week’s economic data continues to point to recovery, but investors worry whether it will be strong enough to support the stock rally since March 9th. The S&P fell 2.6% this week as of yesterday’s close. September is historically the worst month for the stock market. In fact as Ed Yardeni notes, since 1926, September is the only month with a negative average return. Investors lose an average of 1% during September compared to a 1% return for the other 11 months. So the market may be in a holding pattern for a while. This is a good time to forego analysis of the various economic and market wiggles to take a broader and longer perspective on investing.

In the process of investing we spend a great deal of time in linear thinking. We measure, we weigh, we time, and we project. We draw lots of lines as we make our assertions and projections. The regulatory agencies require us to disclaim that past results do not guarantee future results, but we all, to various degrees, subscribe to that very notion. The multi-billion dollar marketing machine we’ll simply call Wall Street spends millions of dollars a day drawing lines which analyze, dissect, compare, measure, and highlight past results. There is an implication that the more colorful and complicated these reports are the better equipped we are to decide their appropriateness for the future.
