Political Indicators
It is plausible that political winds might sway the economy and therefore financial markets. To what degree do politics matter for equity investors? Should they worry about the philosophy of the party in power or unusual market behavior relative to elections? Should they act on the prognostications of political experts? These blog entries address relationships between politics and the stock market.
Hope for Stocks Around Inauguration Days? January 9, 2009
Do investors (at least a plurality of them) tend to become more optimistic around U.S. presidential inauguration days, focusing on favorable changes for the coming four years and thereby pushing stock prices up? To investigate, we analyze the historical returns of the Dow Jones Industrial Average (DJIA) from five trading trading days before inauguration day through five trading days after inauguration day. Using historical inauguration dates since 1929 and daily closing levels of DJIA for October 1928 through December 2008 (20 inaugurations), we find that: More…
“It’s the P/E, Stupid!” December 16, 2008
Is there a relationship between investor risk-aversion, as indicated by the aggregate U.S. stock market price-earnings ratio (P/E), and level of public satisfaction with the performance of the President? In their December 2008 paper entitled “Speculating on Presidential Success: Exploring the Link between the Price-Earnings Ratio and Approval Ratings”, Tomasz Wisniewski, Geoffrey Lightfoot and Simon Lilley examine the relationship between aggregate stock market P/E and the surveyed level of public approval of the current President. Using quarterly P/E for the S&P Composite Stock Price Index derived from Robert Shiller’s long-run dataset and Gallup presidential approval survey data from the beginning of 1950 through the third quarter of 2007 (231 observations), they conclude that: More…
Spectral Analysis of Stock Market Cyclicality December 2, 2008
Are there reliable periodicities in U.S. stock returns tied to national election cycles? In their October 2008 paper entitled “Financial Astrology: Mapping the Presidential Election Cycle in US Stock Markets”, Wing-Keung Wong and Michael McAleer apply spectral analysis to identify and quantify cycles in U.S. stock market returns, including a presidential election cycle. Using weekly S&P 500 index data for the period 1965-2003, they conclude that: More…
Any Investor Response to Presidential Polling Data? October 15, 2008
Do presidential election polling data have any effect on stock returns? In other words, do investors act on the survey-indicated election prospects for the two major party candidates? Presumably, investors would tend to enter (exit) stocks if they thought the candidate with policies more (less) favorable for equity valuation were gaining ground. Using Gallup Daily polling data and contemporaneous daily closing levels of the S&P 500 index from June 6 (when the major party nominations solidified) through October 14 (91 trading days), we find that: More…
Monthly Returns During Presidential Election Years June 16, 2008
Do the emotions of presidential elections in the U.S. affect monthly stock returns, either elevating returns based on hope or suppressing them based on uncertainty? To check, we compare returns by calendar month for the Dow Jones Industrial Average (DJIA) during presidential election years to returns during non-election years. Using monthly adjusted closes for the DJIA over the period October 1928 through May 2008 (81+ years and 20+ presidential election years), we find that: More…
Presidential Politics and Industry Returns March 25, 2008
Do certain market industries outperform when Democrats or Republicans hold the U.S. presidency, or during certain years of the presidential term? In their recent paper entitled “Political Cycles in US Industry Returns”, Jeffrey Stangl and Ben Jacobsen investigate whether specific industries tend to perform better: (1) under Democratic or Republican presidents; and (2) during the last two years of a presidency. Using return data for 48 industries representing all stocks listed on the major U.S. exchanges during 1926-2006, they conclude that: More…
Political Influences on Stock Valuation Levels July 26, 2007
Do political factors influence stock valuation levels? In his July 2007 paper entitled “Can Political Factors Explain the Behavior of Stock Prices Beyond the Standard Present Value Models?”, Tomasz Wisniewski explores the degree to which political factors affect valuation of U.S. equities. Specifically, he examines whether party holding the Presidency (12 presidencies), Presidential approval ratings and timing of eight major military conflicts affect stock price levels relative to rational valuation models. Using data from a variety of sources for the period 1945-2005, he concludes that: More…
Left Versus Right Down Under May 3, 2007
Are “hands-off” (right-leaning) governments better for stocks than “hands-on” (left-leaning) governments? In their recent paper entitled “Investment Returns Under Right- and Left-Wing Governments in Australasia”, Hamish Anderson, Christopher Malone and Ben Marshall examine the effect of ruling party orientation on inflation, and thereby on stock, property and bond returns, in Australia and New Zealand. Using monthly, annual and political-term data as available across the period 1910-2006, they find that: More…
The Political Campaign Contribution Effect October 31, 2006
Do companies that “grease the wheels” of our political system via campaign contributions benefit from such participation? In other words, is there a significant positive correlation between company campaign contributions and stock returns? In their October 2006 paper entitled “Corporate Political Contributions and Stock Returns”, Michael Cooper, Huseyin Gulen and Alexei Ovtchinnikov construct a measure of the breadth of company campaign contribution activity and investigate whether this measure relates systematically to returns for shareholders. Combining data from the Federal Election Commission on political action committee (PAC) contributions of publicly traded firms for the period 1979-2004 (over 800,000 contributions by 1,930 firms) with associated stock price and financial data, they conclude that: More…
A Republican Risk Premium? August 22, 2006
Is the media more likely to accentuate the negative when Republicans hold the Presidency? In their October 2004 paper entitled “Is Newspaper Coverage of Economic Events Politically Biased?”, John Lott Jr. and Kevin Hassett of the American Enterprise Institute test for political bias in the economic (durable goods, GDP, retail sales and unemployment) news coverage of American newspapers, after controlling for economic content. Using headlines from a database of newspaper and wire service articles from 389 newspapers covering January 1991 through May 2004 (and back to 1985 for the top ten newspapers: USA Today, Wall Street Journal, New York Times, Los Angeles Times, Washington Post, New York Daily News, New York Post, Chicago Tribune, Newsday and Houston Chronicle), they find that: More…
