Compare Early 2012 S&P 500 Forecasts With Current Market And Statistical Indicators

| About: SPDR S&P (SPY)

This article compares the 2012 year-end price forecasts for the S&P 500 (Proxy: SPY) from leading research sources, with where the index is today, and what various statistically generated price probabilities say about the year-end price.

On December 27, 2011 "Business Insider" published analyst forecasts, as follows:

  • Morgan Stanley: 1167
  • Goldman Sachs: 1250
  • UBS: 1325
  • Barclays: 1330
  • Credit Suisse: 1340
  • Bank of America: 1350
  • Black Rock 1350
  • Wells Fargo: 1360
  • Citi: 1375
  • Cumberland Advisors: 1350-1400
  • Nomura: 1400
  • Oppenheimer: 1400
  • Blackstone: 1400
  • Goldman Asset Management: 1400
  • S&P Capital IQ: 1400
  • JP Morgan: 1430
  • Federated Investors: 1450
  • Deutsche Bank: 1500
  • Seabreeze Partners: 1527

Unfortunately, we do not have a complete list of their views recently, but here are a few:

  • Goldman Sachs 1250 (unchanged)
  • UBS: 1325 (unchanged)
  • Barclays: 1325 (reduced 5 points)
  • Deutsche Bank: 1450 (reduced 50 points)

This morning the S&P 500 is at about 1388.

Not a bad forecast so far for most of the analysts.

Let's see what statistical models say about the probability range of price by year-end.

Figure 1:
Linear Regression Best Fit Trendlines

This chart plots the linear regression best fit trend lines from the 2007 market high, the 2009 market low, and from 1 year ago, and extends those lines to 12/31 (lines plotted in blue).

Those three trendlines define a range of year-end values from 1300 to 1470 - very much in accord with the bulk of the analyst forecasts made in December 2011.

The red line plots bear market levels 20% below the 52-week high, and the gold line plots the 200-day moving average.

Figure 2:
Regression Trend Lines With 1.28 Std. Dev. Channels

This chart plots the same linear regression trend lines in Figure 1, but also adds a channel above and below the regression trend at 1.28 standard deviations. That defines (based on historical volatility) the price range that covers 80% of the probable prices (basically a 10% chance of the price lying above the channel, or 10% chance of the price lying below the channel).

From the 2007 high, the range is 1530 to 1060.

From the 2009 low, the range is 1660 to 1260.

From 1 year ago, the range is 1550 to 1375.

As we will see when we look at options indication, only the 1375 value has a significant chance of being achieved by year-end.

Figure 3:
Volatility-Based Price Probability Ranges

This chart plots two price range probability cones at the 80% level -- meaning that there is a 20% chance of the price occurring outside of the cones (roughly 10% above and 10% below).

The red cone is based on the current VIX level of about 15, and predicts the 80% range high at 1480 and the low at 1300. VIX is based on options pricing and is forward looking.

The blue cone is based on the 1-year actual historical volatility of the index; and is therefore backward looking in its rationale. Its 80% price probability high is 1455 and its low is 1320.

These values support the year-end forecasts made by all the listed analysts except Morgan Stanley and Goldman Sachs, which are below the cones; and Deutsche Bank and Seabreeze Partners, which are above the cones.

Why Bother With Statistical Forecasts At All? When we have written about probability ranges in the past, there is always someone who says the exercise is completely pointless, because there is no specific price forecast, or that the range is too wide. Clearly, this approach is useless to them, but it is fundamental to options trading, and helpful to stock investors who want some level of indication where boundaries of play may be in a near-term period. The cones and other statistically derived ranges do not tell you where the price will be, but they can be helpful in telling you where they are likely not to be. That can help temper excess enthusiasm or excess pessimism.

Figure 4:
Spread of Recently Stated 2012 Forecasts

This 1-year price chart shows horizontal lines at the recently stated year-end price forecast levels by Deutsche Bank (green line), UBS and Barclays (blue line) and Goldman Sachs (red line).

Goldman has said they expect some unpleasant fiscal cliff outcomes in the short-term that supports their pessimistic price forecast. They do, however, predict a price above 1500 for year-end 2013.

Figure 5:
Statistical and Analyst Year-End Prices Versus Options Implied Probabilities

This chart plots all of the statistical price indications from earlier figures, plus the recently stated price targets from Deutsche Bank, UBS, Barclays and Goldman Sachs.

It also shows the probability of each of the price levels being exceeded on either the upside or downside according to the pricing within December 2012 SPX options (probabilities from OptionsExpress).

The 90% options implied probability range is 1480 to 1300. The linear regression trend line from the 2009 low, and the regression trendline from 1 year ago, each extending to 1470, fit into that 1480 to 1300 range, as does the 1300 for the regression trendline from the 2007 high.

According to options pricing, the 1250 Goldman Sachs forecast has less than a 1% chance of coming true. That doesn't make them wrong, but it does mean that options traders don't believe the scenario.

Figure 6:
Extra-Long Term Regression Trendlines

Perhaps just for fun, let's look at a 30-year monthly chart of the S&P 500, and plot a best fit regression trend line to that. And, let's also plot another regression trend line from 1994, when the character of the market changed, in great part, we think, because that was the year the internet became commercial (the year that HTML and pictures rolled out on the web).

What we find is the 30-year regression trend line extends to 2012 year-end at about 1500, and the regression trendline extends to year-end at about 1405. Very close fit with intermediate-term and short-term trendlines in earlier figures.

It is obvious from the picture that the character of the market changed around 1994. If Jeremy Grantham of GMO is correct, the character is changing again (for the worse). That is not really hard to believe given the mess we and the rest of the developed world are in.

Since we are looking 30 years back, let's entertain Jeremy Grantham's 30+ year forward view.

Grantham, in his latest letter (requires registration) predicts real (inflation adjusted) 1.4% GDP growth through 2050 before large increases in commodity costs he predicts. After commodity costs and costs of environmental remediation, he sees average annual real GDP growth of 0.9% through 2030, and then 0.4% annual growth from 2030-2050. Ugly!

Coming Full Circle:

When analyst forecasts align well with historical volatility generated forecasts and options implied forecasts, there may be the basis for taking some comfort in the reliability of the forecasts most of the time -- but not if there are important events that change everything.

And, that is were we are facing short-term outcomes. We face another set of binary outcomes, based on the behavior of politicians more than the underlying strengths and weaknesses of businesses.

Front and center now is whether the US Congress and President allow the country to go over the cliff or not?

Back row issues now are the European debt crisis, potential for wider war in the Middle East, and the possibility of military confrontation between China and Japan over resource rich areas of the ocean.

One really big upside surprise would be some indication of approvals and regulations that expand the oil and gas sector and associated jobs within the US. Something as simple as approving the Keystone pipeline could do the trick for the stock market.

In the US, we would hope that the people and the media will be as focused on the cliff decision as they are on the fate of Hostess Twinkies and Cupcakes, and the sexual behavior of generals and temptresses.

Our Best Guess:

Taking the three data sources into consideration (analyst forecasts, historical price behavior, and options implied probabilities), and adding our own sense of the political overlay on the markets, this is what we expect at a high probability.

Our own best guess is that we will go over the cliff for a very short period of hours or days, so that each party can blame the other for the problem. Then they would quickly reverse the cliff retroactive to January 1 and defer the deadline out a few months so that they can consider further, perhaps even making some nominal change to "prove" that they are serious.

The result of going over the cliff, or just seeming about to happen, would tend to push the price level of the S&P 500 index toward the lower end of the predicted ranges, such as the low 1300s and maybe high 1200s.

Then when they reverse the cliff and defer the deadline, the price would rally back to about 1400, in a sigh of relief.

If they actually did something that put the US on a believable slope to fiscal sanity, then a big rally above 1500 is quite feasible.

As a result we have an above normal cash level -- not out of stocks or bonds, but a somewhat reduced stocks level.

If we are right, we will re-enter at a lower price, and for taxable accounts will have captured some profits at lower tax rates (almost all of our clients are at the top marginal rates).

If we are wrong, we will probably miss some upside before getting back in, but will have avoided a potentially damaging market slide, and the angst that would cause. However, we have not bet the farm either way - just tilted the table in favor of conservatism.
