Economic Indicators
  
  The U.S. economy is a very complex system, with indicators therefore ambiguous and difficult to interpret. To what degree do macroeconomics and the stock market go hand-in-hand, if at all? Do investors/traders: (1) react to economic readings; (2) anticipate them; or, (3) just muddle along, mostly fooled by randomness? These blog entries address relationships between economic indicators and the stock market.

    Does the stock market react reliably and exploitably to the                      monthly announcements of the change in non-farm  employment                      based on Bureau of Labor Statistics surveys of  employers?                      To check, we examine the typical behavior of stocks  during                      the five trading days before and the five trading  days after                      release dates. Using the unrevised non-farm employment releases and                      contemporaneous daily S&P                      500 index data for the period 2/94-9/07 (164  announcements),                      we find that… Keep Reading

    In seeking to control interest rates, has the Federal Reserve                      become less relevant to equity investors? In his  September                      2007 paper entitled “The Unusual Behavior of the Federal Funds                      and 10-Year Treasury Rates: A Conundrum or  Goodhart’s                      Law?”, Daniel Thornton examines the loss of  correlation                      between the Federal Funds Rate (FFR) and long-term interest                      rates in the context of Goodhart’s Law, which states  that                      “any observed statistical regularity will tend to  collapse                      once pressure is placed upon it for control  purposes.”                      Using monthly data for the FFR and the yields for  Treasury                      instruments of various durations over the period  1/83-3/07,                      he concludes that: Keep Reading

    After reviewing our update of the relationship                       between crude oil price and overall stock market  behavior,                      a reader requested a similar analysis of the  relationship                      between crude oil price and an energy sector  Exchange-Traded                      Fund (ETF) such as Energy Select  Sector S&P Depository Receipts                      (XLE). The reader’s hypothesis is that energy  ETFs follow                      crude oil spot price fairly well. Comparing the weekly crude oil spot price for the U.S. with the weekly  close for XLE for over the period                      1/99-8/07, we find that: Keep Reading

    Some market commentators cite the price of crude oil as an                      important indicator of future stock market behavior.  Is expensive                      crude oil a sign of future inflation or a drag on  aggregate                      corporate earnings, or is it a proxy for general  economic                      strength? Does a local peak (valley) in the price of  crude                      oil portend a falling (rising) overall stock market?  Comparing                      the weekly crude oil spot price for the U.S. with the weekly level of the S&P 500 index for                      the period 1/97-8/07, we find that… Keep Reading

    A reader suggested that            stocks may respond to two second order effects in the Consumer  Price Index (CPI): (1)trend in monthly CPI changes (monthly inflation  rate),              as measured by the slope of changes over a few consecutive  months; and, (2) volatility of monthly CPI changes, as measured  by the              standard deviation of changes over a few consecutive months. Testing these effects with CPI data and monthly S&P  500 index closing levels for estimated            or actual CPI release dates during January 1990 through June  2007 (210            months), we find that: Keep Reading

    A reader notes that many experts are focused            on the recent sharp rise in the 10-year Treasury note (T-note)  yield,            often asserting that such large positive yield shocks are bad  for stocks.            He asks what the historical data say about the relationship  between            short-term shocks in T-note yield and future stock returns.  Using daily            closing T-note yields and daily closing prices for the            S&P 500 index since the beginning of 1990, we             find that: Keep Reading

    What conditions lead to stock market booms and busts, and how does            monetary policy relate to boom-bust transitions? In the May  2007 version            of their paper entitled “Monetary            Policy and Stock Market Booms and Busts in the 20th Century”,  Michael            Bordo, Michael Dueker and David Wheelock examine the  relationship between            monetary policy and stock market booms/busts in the U.S., U.K.  and Germany            during the 20th century. They define booms (busts) as periods  of at            least 36 (24) months from trough to peak (peak to trough) with  at least            10% (20%) average annual increase (decrease) in real stock  prices. Using            monthly inflation-adjusted stock price indexes, they  conclude that: Keep Reading

    Deterioration over the past decade in the forecasting power of traditional indicators (such as price-dividend and price-earnings ratios) have stimulated searches for better ones, with recent emphasis on macroeconomic variables. Which financial and economic variables best predict stock returns over the short, intermediate and long terms? Is “best” good enough for market timing? In her October 2006 paper entitled “How Well Do Financial and Macroeconomic Variables Predict Stock Returns: Time-series and Cross-sectional Evidence”, Anne-Sofie Reng Rasmussen evaluates the relative performance of a wide range of variables in forecasting excess stock returns (above the one-month T-bill rate) over horizons from one quarter to eight years. Using annual data for periods as long as 1930-2005 and quarterly data for periods as long as 1926-2005, she concludes that: Keep Reading

    What kind of economic environment makes a stock market boom? What  changes            in that environment lead to bust? In their September 2006  paper entitled            “When            Do Stock Market Booms Occur? The Macroeconomic and Policy  Environments            of 20th Century Booms”, Michael Bordo and David Wheelock  examine            the economic and policy conditions that supported equity  market booms            in ten developed countries (Australia, Canada, France,  Germany, Italy,            Japan, Netherlands, Sweden, the United Kingdom and the United  States)            during the 20th century. Using monthly inflation-adjusted  stock prices            from these countries, they conclude that: Keep Reading

    In their February 2003 paper entitled “Stock  Returns, Aggregate Earnings Surprises, and Behavioral            Finance”,  Jonathan Lewellen, S. Kothari and Jerold  Warner explore the relationships between            overall stock market behavior and aggregate corporate  earnings, looking            for parallels with firm-level price-earnings behavior. Using  quarterly            data for 1970-2000, they conclude that: Keep Reading
