The Conundrum of Astonishingly Cheap Stocks

The StressTest column appears every Thursday on Check back weekly, and follow @TMFStressTest on Twitter.

Stocks are cheap. No, really. They're very, very cheap.

If you ask the right people, you'll hear that stocks are cheap because the equity risk premium has skyrocketed. Just check out this nifty chart from the New York Federal Reserve Bank's Liberty Street Economics blog.

"Now, back up a minute," you may be saying. "What is this equity risk premium you speak of?"

I'm glad you asked. The equity risk premium measures the implied additional returns that investors get for investing in stocks as opposed to putting their money in an instrument that delivers the "risk-free rate" -- often assumed to be U.S. Treasuries. If, for example, the S&P 500's (SNPINDEX: ^GSPC  ) price-to-earnings ratio (P/E) was 15 -- and, therefore, the earnings yield was 6.7% -- and the risk-free rate was 3%, then we could say that the equity risk premium was 3.7%. (That's not the primary or only way to calculate the equity risk premium; I just used it for ease of illustration.)

When the equity risk premium is very low, stocks become less attractive because investors aren't getting much additional returns for the additional risk they're taking on by investing in stocks (remember, the alternative is "risk free"). On the other hand, when the equity risk premium is particularly high, it can be a fantastic time to invest in stocks because investors can expect a hefty helping of above-risk-free returns.

As the chart above shows, the folks at Liberty Street have concluded that we're solidly in that latter situation right now:

The value of 5.4 percent for December 2012 is about as high as it's ever been. The previous two peaks correspond to November 1974 and January 2009. Those were dicey times. ... It is difficult to argue that we're living in rosy times, but we are surely in better shape now than then.

Fair points about both 1974 and 2009. But dicey times or not, for both 1974 and 2009, stock market results over the next five to 10 years were pretty darn attractive.

And it's not just the wonks at the Fed that care about this equity risk premium. When Appaloosa Management's David Tepper went on CNBC earlier this week and got the whole market all hot and bothered, he waved around the above chart as part of his bullish thesis. And for those not familiar with Tepper, he's no piker -- Appaloosa manages around $18 billion.

So, cheap stocks, great news. Right?

It's slightly more complicated than that. As outlined above, the equity risk premium is calculated in relation to the risk-free rate. We currently have a sky-high equity risk premium, that's true. But at the same time, we have an absolutely rock-bottom risk-free rate -- five-year Treasuries are yielding far less than 1%.

So, yes, investors can expect to see returns from stocks significantly outperform those of risk-free fixed income securities, but on an absolute-returns basis, the situation is very different from 1974 or 2009. Back then, stocks were actually cheap. According to Robert Shiller's data, the cyclically adjusted P/E (the 10-year P/E, aka "CAPE") dropped as low as 8.3 in 1974. In 2009, we saw a CAPE of 13.3. As of Shiller's most recent numbers, the S&P's CAPE is currently at 23.2.

To be clear, I'm not arguing that stocks are wildly overvalued. But it's important to consider that some measures of stocks' "cheapness" may not be what they seem. Warren Buffett has said that interest rates "act on financial valuations the way gravity acts on matter: The higher the rate, the greater the downward pull." In the current rate environment, gravity is about as strong as it is on the moon. 

I think there are stocks out there offering reasonable absolute return prospects. At Appaloosa, Tepper has some larger positions in financials like Citigroup  (NYSE: C  ) and MetLife  (NYSE: MET  ) -- I see that in particular as a sector where deals are still available. The fund also has Apple  (NASDAQ: AAPL  ) and General Motors  (NYSE: GM  ) among its top 10 positions. In both of those cases, there's also a solid value case to be made. After long avoiding Apple myself, I added some to my portfolio earlier this year as the valuation simply looked too good to pass up. In short, even as Tepper professes a bullishness on the overall market, Appaloosa's portfolio looks very selective and value driven.

The point is, there are opportunities, but it's important to be choosy. And it will likely be even more important to be selective going forward. If the equity risk premium does start to converge with historical averages, it will most likely be for one of two reasons: interest rates are (finally) climbing, or stock valuations are rising. The latter in particular could make the market seem even more attractive in the short to medium term as prices push upward, but the move will only further squeeze potential future absolute returns.

So are stocks cheap after all? Sadly, as with so many other important questions, the answer depends a lot on how you define the question.

Is Citi a buy right now?
Citigroup's stock looks tantalizingly cheap. Yet the bank's balance sheet is still in need of more repair, and there's a considerable amount of uncertainty after a shocking management shakeup. Should investors be treading carefully, or jumping on an opportunity to buy? To help figure out whether Citigroup deserves a spot on your watchlist, I invite you to read our premium research report on the bank today. We'll fill you in on both reasons to buy and reasons to sell Citigroup, and what areas Citigroup investors need to watch going forward. Click here now for instant access to our best expert's take on Citigroup.

    Hedge funds are a good place to look to see where the big money is going. That doesn't mean one should copy or guess at what the fund has in the back of their mind. Very recently more then a few hedge funds sold their stake in APPL. Does that mean we should sell our stake in AAPL? Not me. I'll give it time. I thought the article explained what an "equity risk premium" is but didn't give us a way of applying it. Frankly, I'm past the point of trusting almost anything I read or hear. I do my own work and buy what I think will make money for me. MF helps but articles like this don't. Sorry but I feel many stocks are way overpriced as they flirt with their 52 week high. My gut says, considering the economy etc.., the stocks will drop when people stop spending. I feel we are headed for a correction and that's the time for me to buy. I'm resting & watching now.
