Jeremy Grantham Calls the Next Market Top
The investing legend writes that the S&P 500 could gain another 10% before “crashing at it always does.”

As you may remember, the January Rule serves as a kind of barometer for the behavior of the market in the coming year. Historically, when January was down, the rest of the year had over twice the declines than one would expect randomly, far more mediocre months, and a very sub average return. But it is far from perfect and it had the unusual problem this year of bumping into the positive signal from the presidential third year, which started for us on Oct. 1. 

For the statistically-minded, or the trivia-minded, the four previous such conflicts between the January Rule and the Presidential Cycle were inconclusive but the simple rule would have been to end the January Rule enterprise on Sept. 30. This year was flattish by then and the new Presidential Cycle has gotten off to a good start since Sept. 30. 

The Presidential Cycle Regular readers know the score: +2.5% a month for the seven months from Oct. 1 to April 30, in year three on average since 1932 (a total of +17%). This is now the 21st cycle. The odds of drawing 20 random seven-month returns this strong are just over 1 in 200 according to our 10 million trials. But 17 of the actual 20 historical experiences were up and the worst of the 3 downs was only -6.4%, so the odds of this consistency plus the high return would be much smaller. 

The remaining five months of the presidential year have a good but not remarkable record, over .75% per month, but the killer here is that the remaining 36 months since 1932 averaged a measly +0.2% a month!
With the seven months having returned over 10 times the average of the 36-month desert, it may seem like a no-brainer investment for those seven of us not intimidated by the obvious simplicity of the idea, but be advised that going into this particular cycle there appear to be more negatives than normal. 

(Though many of the previous 20 occurrences may well have seemed that way to investors at the time. Who knows?) The negatives this time include the ending of the Federal Reserve’s bond purchase program. There is also talk of a rate increase early next year, given the recent recovery of the U.S. economy reflected in the improved employment report of early October (5.9% unemployed) and positive adjustments to the previous month’s employment numbers. Other negatives include the potential for escalation of several minor but intractable wars and the recent Ebola outbreak. 

Some would mention the very substantial overpricing of the U.S. market (ticker: SPY ) at the top of the list but, surprisingly, overpricing has had no material effect on third-year returns or the particularly sweet seven-month subset: an average of 17% for seven months becomes 19% if cheap and 15% if expensive. Big deal. 

Value, however, is very important for the other three years in which the cheapest 25% have produced a respectable return of +12%, and the other three quartiles are absolutely not worth having, all three together averaging almost exactly nil! More disturbing to me than the obvious overvaluation is the large and growing number of other negatives – technical and psychological – put together by John Hussman and other market experts. 

Nevertheless, despite my nervousness I am still a believer that the Fed will engineer a fully-fledged bubble (S&P 500 over 2250) before a very serious decline. 

The Prudent Investor As always, the prudent investor (unlike the political year three) should definitely recognize overvaluation, factor in regression to the mean, and calculate the longer-term returns that result from this process. More easily, such prudent investors can use our seven-year numbers, which have a decent long-term record measured when we have viewed markets as overpriced, as we believe they are today, and a better record measured in the periods after bubbles break. The other necessary ingredients to the investment mix are suitable measures of risk, and when these are added to estimated returns we believe efficient portfolios can be produced. On our data, with U.S. large cap equities offering negative returns (-1.5%) except for high quality stocks (+2.2%), with foreign developed and emerging equities overpriced (+3.7%), and with bonds and cash also very unattractive, investors have to twist and turn to find even a semi-respectable portfolio....MORE
