NEW YORK (TheStreet) -- The biggest event for investors over the next six months is likely to be the November elections in the U.S. The outcome of the elections will define the political context and leadership for policies that address the looming fiscal imbalances coming to a head in early 2013.

We have explored this budget bombshell in prior commentaries and what it could mean for the markets and economy. This week we will take a look at what the market is pricing in regarding the election outcome.

As we explore the issue of what the market is pricing in when it comes to the outcomes of the November elections, it is important to be aware of the shortcomings of overly simplistic election analysis.

An illustration of this can be seen in Chart 1, where we plot the odds of President Obama's re-election (measured by contracts traded on and the movements in the stock market, measured by the S&P 500 Index. Is the stock market going up because of the rise in Obama's re-election odds, or are Obama's re-election odds going up because the stock market is rising -- or, more likely, are both tied to something else?

The S&P 500 is an unmanaged index, which cannot be invested into directly. Past performance is no guarantee of future results.

Attempting to draw simple conclusions about what the market is saying about the election is fraught with the potential for misinterpretation. Instead, there is a better, more analytical way for investors to attempt this kind of potentially rewarding analysis. Analyzing the market by the industries most impacted one way or another by the election outcome can provide more precise insight into what the market is pricing in regarding the election.

For example, the components of the 10 stock market sectors are impacted in different ways by election outcomes:
  • Health Care is the biggest driver of the long-term budget problems at the Federal level. States are already cutting Medicaid to balance their budgets. A sweeping win for the GOP holds the most promise for Managed Care providers as risks decline and investors increase the odds for a repeal of all or part of the Affordable Care Act. Diagnostic labs, generic drug makers, hospitals, and nursing homes may benefit if the Act is upheld and from Democrats' leadership, given expanded health care coverage and an emphasis on preventative care and legislation to speed up the introduction of generic drugs to market.
  • We may see a relief rally among the banks in the legislation-sensitive Financial sector. If the GOP takes the Senate it will result in the change of chairmanships of key committees. While major changes to the financial reform law, Dodd-Frank, are unlikely, an all GOP Congress might influence regulations implementing the law. On the other hand, Republicans would likely look to address Fannie Mae and Freddie Mac conspicuously left out of the Democrat-led financial reform law, which could have negative ramifications on home loan originators. Democrats may also provide more housing support programs benefitting home builders and construction materials providers.
  • As previously mentioned, the potential extension of Bush tax cuts would mean the dividend tax rate may remain closer to 15% instead of going to 43.4%, a plus for companies with lots of cash to distribute. High dividend-paying sectors such as Telecommunications Services, Consumer Staples, and Utilities may benefit. Cash-rich companies in other sectors may also benefit as they introduce or substantially increase their dividend payout as they look to attract a new class of investor seeking yield. Alternatively, some food and staples retailers may benefit from potential for a further extension of unemployment benefits.
  • Companies in the Energy sector may be impacted by a strong election for the GOP in a number of ways. Regulations on drilling would be more favorable as would EPA regulations. We could see lower regulatory costs for producers in the Materials sector and users of coal such as Utilities. Gas may benefit from stricter coal regulations under the Democrats. On the other hand, alternative energy companies would face a less supportive outlook for subsidies under a GOP outcome.
  • Sectors highly sensitive to trade, including Technology, may benefit from a strong showing by the GOP. The Consumer Discretionary sector could also benefit from the diminished risk of China trade protectionism -- a plus for retailers dependent on low-cost imports and U.S. exporters of capital equipment fearing Chinese retaliation.
  • The election could hold positives and negatives for companies in the Industrial sector. At 20% of the budget, defense spending will likely see cuts next year, but would likely see a more shallow trimming under the GOP than Democrats. On the other hand, transportation funding will likely be smaller under GOP leadership, resulting in fewer government dollars for engineering and construction companies.
  • While there are many "man on the street" polls, what matters most to investors is what is priced in on Wall Street rather than what people are saying on Main Street. A stock market based "election poll" is useful in that it highlights what the market is pricing in about the outcome of the election that is more refined than merely looking at the overall market.

    Based upon these legislation-sensitive industries, we have created two indices to help us track the markets' implied forecast of the election outcome reflected in the performance of these industries. Each index is composed of an equal weighting among seven industries that combined total about 100 S&P 500 stocks.

    To track what the market has priced in for the Democrats' odds of retaining the White House and Senate we have taken the Democrats index and divided it by the Republicans index. An upward sloping line suggests the market may be pricing in a rising likelihood of the Democrats retaining the White House and their majority in the Senate, while a downward sloping line suggests improving prospects for the Republicans. While other factors may influence the relative performance of these indexes, as time goes on the election consequences may become paramount as investors increasingly vote with their money. As you can see in Chart 2, already this year Obama's re-election odds on are generally tracking the relative strength of our Democrat vs. Republican indices.

    If you elect to follow our "Wall Street' election poll index, we pledge to continue to keep you informed as to how these issues are likely to affect the markets. We will update this index frequently as the election becomes an increasingly important driver of the markets over the coming six months.
