The Palin Barracuda Index (PBI) closed the week at 101.4, up 1.9 points from 9/5.
The purpose of this index is to measure how the market assesses the likely change in tax policy in the upcoming presidential election. Increases in the index indicate the market feels a McCain victory is more likely, while decreases indicate an increased probability of an Obama victory. The tension between these candidates, boils down to keeping capital gains taxes low, and trying to control and/or reduce the size of government versus increasing capital gains taxes and expanding government’s role in the economy. Given the contrasts between McCain and Obama in these areas, examining the relative returns of growth and value stocks seems like a natural way to quantify the market’s view as to how the race is progressing. For a review of how taxes and inflation affect growth and value stocks look here. For a specific look at how taxes affect growth and value stocks look here.
The increase in the PBI this week is consistent with a favorable week for the McCain campaign.
1. Barack Obama spent a significant part of the week addressing Sarah Palin rather than John McCain.
2. Barack Obama has shifted his campaign strategy to pursue a more negative and attacking tone against John McCain.
3. Sarah Palin passed an ongoing “gotcha” interview with Charles Gibson.
Since introducing the Palin Barracuda Index, I have received many emails to clarify how to use this tool. So here are a few thoughts.
1. This is not a predictive model that maps neatly into probabilities. In other words, if the index reads 110 a week before the election we cannot say McCain will win with 80% probability, 70% probability, or any specific probability. We can interpret such a value as that the market is more confident about McCain winning relative to when I launched the index on 9/4/08.
2. The index does not have anything to do with Sarah Palin affecting growth stocks after the election. I created this index, as when Sara Palin was introduced to the American public she seemed to be a genuine game changer regarding the election’s outcome. Because McCain’s platform to keep capital gains taxes low and control government spending is more favorable for growth stocks relative to value stocks, I thought this index would be a relevant way to get an independent look at how the election is unfolding.
3. Why not just rely on Intrade or other “predictive markets”?. While those markets are interesting, they tend to be thinly traded, and seem to reflect prices that sometimes reflect emotion rather than fact. For example, Ron Paul tended to trade at unreasonably high prices, most likely caused by his avid followers wishing to keep him in the news. Therefore while those markets are interesting, using the depth of the stock market provides a much more robust perspective.
4. The relative returns between growth and value stocks are affected by more than just potential changes in tax rates. I agree that many issues affect the relative attractiveness of growth and value stocks, but given the short time period between when I launched the index and the election, I believe the most relevant issue affecting stocks will be how these tax and governmental philosophy issues get resolved. During this time there will be events and issues that come up and add noise to our interpretation, but in general I think the market will give us a clear direction as to who will win by voting with billions of dollars between growth and value stocks.
Over the next week I will try to provide some historical perspective on the PBI to quantify what consitutes a significant move over a particular period of time. I will also try to take a deeper look at its construction, to try and prevent any significant sector concentrations from affecting the returns in the coming weeks.
