According to Bloomberg, investors are the most optimistic on stocks they have been in 3½ years. As is normal, investors mistake a sense of optimism about the economy for a sense of optimism on equities. As is normal, investors are reaching this peak of optimism as the stock market achieves its highest nominal level in five years, and among the highest valuation multiples in ... hey!...about five years. What a coincidence! (Incidentally, while we calculate our long-term valuation metrics ourselves this page is a pretty good source for a quick-and-dirty view of valuations. I don't have any relationship to the company and this is the only page on the site that I've used so I am not endorsing any other page!)

Now, while I am probably as optimistic on the economy as I have been in the past few years, I'm still less-optimistic than the crowd since I think the crowd hasn't yet assimilated the fact that the little growth spurt at the end of Q4 owes quite a lot to the movement of dividends and incomes into Q4 from Q1, and thus the first quarter of this year will probably look rather poor.

In fact, while I am clearly negative long-term on the prospects for nominal Treasury bonds, that's my investment view. My trading view is that at 1.84%, Treasury bond yields are probably going to go lower before they go higher. That's partly because the present yields incorporate a lot of enthusiasm about growth - enthusiasm I think will be dashed once the January numbers begin to be reported in earnest. But the trading view is also because the Fed is buying virtually all of the net supply the Treasury is supplying to the market, with no sign that project is ending. I have no illusions that buying 10-year Treasuries at 1.84% and holding to maturity will be an awful investment. But if I was a short-term swing trader, I'd play for the next 20bps to be lower, not higher, in yield.

With respect to January data, incidentally, here is what we have so far (outside of Initial Claims, which as I have pointed out previously are all over the map at this time of year):

For the most part, these are not just misses but big misses. I wonder how long it will take for investors to notice? Initial Claims on Thursday could get attention as the numbers start to converge on the actual condition of the underlying economy, but the first big January datum is the January 29th release of Consumer Confidence, which is currently expected to rise slightly from December. That is followed by ADP on January 30th (but any weakness there will likely be tempered by the advance release of Q4 GDP on the same day), the Chicago PMI on the 31st, and the ISM PMI and Unemployment on February 1st. Regardless of what happens over the next few days, I don't want to be short bonds headed into that gauntlet next week.

I said the January data were big misses "for the most part," because the NAHB miss wasn't really a big miss. Housing is even strong enough now to resist downside surprises. As an aside, although it is a December number, the median price of existing home sales rose 10.89% year-on-year. Adjusted for the level of core inflation (so that we're looking at the real rise in existing home prices), this is the fastest rise in history except for several months in 2005 - see the chart, (source Enduring Investments).

As for stocks, the fact that investors are as bullish as they have been in a third of a decade is sad but not terribly surprising (although this is a survey of Bloomberg users, which supposedly are much more astute since they have to come up with the 1700 clams per month for the service). On a related note, I was recently reading an article, called "I Saw The Movie," in the January issue of Financial Advisor Magazine. In the article, the author compares the fear that some investors have of the stock market to the (irrational) fear of going into the water after watching Jaws. The author notes that "If your balance in 2011 resembled your balance in early 2008, you lost three years - but you didn't lose any money, unless you sold out of panic...the vast majority of big losers were those who sold at the ebb of fall of '08 to the spring of '09 and parked their boats in the shallows of rock-bottom savings accounts."

This, it occurs to me, is the real toll that the Fed's QE has had on the investor class. It taught the wrong lesson. The lesson that has been taught is that you should hold on through all things, good and bad, and things will be okay. It is true that with hindsight, those who sold with the market finally at fair value (but no cheaper) in March of '09 missed a rollicking rally all the way back to similar levels of overvaluation. But the real lesson should have been that most investors shouldn't have been overweight in equities in 2008 or in 2007, based on market valuations. In the absence of manipulation of asset prices through the "portfolio balance channel" (see my discussion of this phenomenon in my recent article "A Relatively Good Deal Doesn't Mean It's A Good Deal"), those who sold in March of 2009 would have missed an average market return rather than the 21% per annum the market actually delivered since then. So the problem isn't that they got out in 2009, but that they got in (or stayed in) in 2007 and 2008, and then got out in 2009. Investors who heeded the overvaluation of the market at, say, year-end 1998 and never got back in have earned a compounded return of 2.54% in T-Bills, 7.39% in TIPS, 5.64% in commodities, or 5.77% in the Lehman/Barclays Agg (nominal bonds) compared with 2.94% in stocks.

And that return is based on the pumped-up valuations that still exist in stocks today.

Investors, and their advisors for the most part, haven't learned the right lessons yet, which is why patient investors are still having to wait to get back into equities even though the Federal Reserve is working very hard to force them back into the market via the portfolio balance channel.

The right lesson is this: investing for the long term is mostly about valuations, and very little about the economic cycle, the news cycle, or the lunar cycle. And two of those three we can't predict, anyway. Yes, there is a tactical element of trading, but most investors should be (a) rebalancing on a regular basis, (b) paying attention to basic rudiments of asset valuation so as to adjust - mainly at the margin - their basic asset mix, and (c) turning off the television.
