Just nigh a calendar week ago, I was on a 13-hour bird trip from Tokyo to New York. I know that this volition audio foreign but I similar long flights for 2 reasons. The starting fourth dimension is that they laissez passer me extended stretches of fourth dimension when I tin function without interruption, no knocks on the door or e-mail or telephone calls. I readied my lecture notes for side past times side semester in addition to reviewed in addition to edited a manuscript for i of my books inwards the starting fourth dimension one-half on the trip. The minute is that I tin move on moving painting binges amongst my remaining time, watching movies that I would conduct hold neither the fourth dimension nor the patience to spotter otherwise. On this trip, however, I made the bad determination of watching Batman versus Superman, Dawn of Justice, a movie thus bad that the only agency that I was able to larn through it was past times letting my hear wander, a practise that I indulge inwards oft in addition to without apologies or guilt. I pondered whether Superman needed his suit or to a greater extent than importantly, his cape, to fly. After all, his powers come upward from his origins (that he was born inwards Krypton) in addition to non from his outfit in addition to the cape seems to live to a greater extent than of an aerodynamic drag than an augmentation. These deep thoughts nigh Superman's cape in addition to thus led me to thinking nigh CAPE, the variant on PE ratios that Robert Shiller developed, in addition to how many articles I conduct hold read over the terminal decade that conduct hold used this mensurate equally the ground for alarm me that stocks are headed for a fall. Finally, I started thinking nigh Kryptonite, the centre that renders Superman helpless, in addition to what would live analogous to it inwards the stock market. I did tell you lot that I conduct hold a wandering hear in addition to so, if you lot don't similar Superman or stocks, consider yourself forewarned!
The Stock Market’s CAPE
As stocks hitting i high later on another, the stock marketplace looks similar Superman, soaring to novel highs in addition to possessed of super powers.
There are many who warn us that stocks are overheating in addition to that a autumn is imminent. Some of this worrying is natural, given the market's rising over the terminal few years, but at that spot are a few who seem to conduct hold surrendered solely to the notion that stocks are inwards a bubble in addition to that at that spot is no rational explanation for why investors would invest inwards them. In a post from a brace of years ago, I titled these people equally bubblers in addition to classified them into doomsday, articulatio genus jerk, conspiratorial, righteous in addition to rational bubblers. The terminal grouping (rational bubblers) are by in addition to large sensible people, who having fallen inwards dear amongst a marketplace metric, are unable to distance themselves from it.
One of the primary weapons that rational bubblers purpose to dorsum upward their representative is the Cyclically Adjusted Price Earnings (CAPE), a mensurate developed in addition to popularized past times Robert Shiller, Nobel prize winner whose soothsaying credentials were amplified past times his calls on the dot com in addition to housing bubbles. For those who don’t quite grasp what the CAPE is, it is the conventional PE ratio for stocks, amongst 2 adjustments to the earnings. First, instead of using the most recent year’s earnings, it is computed equally the average lucre over the prior 10 years. Second, to allow for the effects of inflation, the lucre inwards prior years is adjusted for inflation. The CAPE representative against stocks is a uncomplicated i to brand in addition to it is best seen past times graphing Shiller’s version of it over time.

| Shiller CAPE information (from his site) |
The electrical flow CAPE of 27.27 is good inwards a higher house the historic average of 16.06 in addition to if you lot purchase into the notion of hateful reversion, the representative makes itself, right? Not quite! As you lot tin see, fifty-fifty inside the CAPE story, at that spot are holes, largely depending upon what fourth dimension catamenia you lot purpose for your averaging. Relative to the fully history, the CAPE looks high today, but relative to the terminal twenty years, the story is much weaker. Contrary to pop view, hateful reversion is real much inwards the eyes of the beholder.
The CAPE’s Weakest Links
The CAPE’s Weakest Links
Robert Shiller has been a forcefulness inwards finance, forcing us to await at the consequences of investor behaviour in addition to chronicling the consequences of “irrational exuberance”. His function amongst Karl Case inwards developing a existent estate index that is directly widely followed has introduced dependent area in addition to accountability into existent estate investing in addition to his historical information serial on stocks, which he thus generously shares amongst us, is invaluable. You tin almost view the “but” coming in addition to I volition non disappoint you. Of all of his creations, I detect CAPE to live non only the to the lowest degree compelling but also potentially the most dangerous, inwards terms of how often it tin Pb investors astray. So, at the jeopardy of angering those of you lot who are CAPE followers, hither is my representative against putting likewise much organized faith inwards this measure, amongst much of it representing updates of my post from 2 years ago.
1. The CAPE is non that informative
The notion that CAPE is a pregnant improvement on conventional PE is based on the 2 adjustments that it makes, starting fourth dimension past times replacing lucre inwards the most recent catamenia amongst average lucre over 10 years in addition to the minute past times adjusting past times lucre for inflation to brand them comparable to electrical flow earnings. Both adjustments brand intuitive feel but at to the lowest degree inwards the context of the overall market, I am non certain that either adjustment makes much of a difference. In the graph below, I exhibit the trailing PE, normalized PE (using the average lucre over the terminal 10 years) in addition to CAPE for the S&P 500 from 1969 to 2016 (last twelve months). I also exhibit Shiller's CAPE, which is based on a broader grouping of US stocks inwards the same graph.

2. The CAPE is non that predictive
The inquiry in addition to thus becomes whether using the CAPE equally a valuation metric yields judgments nigh stocks that are superior to those based upon simply PE or normalized PE. To examination this proposition, I looked at the correlation betwixt the values of dissimilar metrics, including trailing PE, CAPE, the inverse of the dividend yield, lucre yield in addition to the ratio of Shiller PE to the Bond PE) today in addition to stock returns inwards the next yr in addition to the next v years:
There is both expert intelligence in addition to bad intelligence for those who purpose the Shiller CAPE equally their stock valuation metric. The expert intelligence is that the fundamental proposition that stocks are to a greater extent than probable to move downward inwards hereafter periods, if the Shiller CAPE is high today, seems to live backed up. The bad intelligence is 2 fold. First, the human relationship is noisy or inwards investment parlance, the predictive mightiness is low, peculiarly amongst one-year returns. Second, the trailing PE genuinely does a amend chore of predicting one-year returns than the CAPE in addition to spell CAPE becomes the amend predictor than trailing PE over a five-year period, it is barely amend than using a dividend yield indicator. While I conduct hold non included these inwards the table, I volition wager that whatever multiple (such equally EV to EBITDA) would do equally expert (or equally bad, depending on your perspective) a chore equally marketplace timing.
As a follow-up, I ran a uncomplicated examination of the reward to marketplace timing, using the Shiller CAPE in addition to actual stock returns from 1927 to 2016. At the start of every year, I starting fourth dimension computed the median value of the Shiller CAPE over the previous 50 years in addition to assumed an over priced threshold at 25% inwards a higher house the median (which you lot tin change). If the actual CAPE was higher than the threshold, I assumed that you lot set all your coin inwards treasury bills for the next yr in addition to that if the CAPE was lower than the threshold, that you lot invested all your coin inwards equities. (You tin alter these values equally well). I computed how much $100 invested inwards the marketplace inwards 1927 would conduct hold been worth inwards August of 2016, amongst in addition to without the marketplace timing based on the CAPE:
Note that equally you lot trust CAPE to a greater extent than in addition to to a greater extent than (using lower thresholds in addition to adjusting your equity allotment more), you lot do to a greater extent than in addition to to a greater extent than impairment to the end-value of your portfolio. The bottom delineate is that it is tough to larn a reward from marketplace timing, fifty-fifty when the pricing metric that you lot are using comes amongst impeccable credentials.

3. Investing is relative, non absolute
Notwithstanding its weak spots, let’s accept the CAPE equally your mensurate of stock marketplace valuation. Is a CAPE of 27.27 likewise high, peculiarly when the historic norm is closer to 16? The respond to you lot may audio obvious, but before you lot do answer, you lot conduct hold to consider where you lot would set your coin instead. If you lot select non to purchase stocks, your immediate alternative is to set your coin inwards bonds in addition to the base of operations charge per unit of measurement that drives the bond marketplace is the yield on a riskless (or about riskless) investment. Using the US treasury bond equally a proxy for this riskless charge per unit of measurement inwards the United States, I create a bond PE ratio using that rate:
Bond PE = 1/ Treasury Bond Rate
Thus, if you lot invest inwards a treasury bond on August 22, amongst a yield of 1.54%, you lot are effectively paying 64.94 (1/.0154) times your earnings. In the graph below, I graph Shiller’s measures of the CAPE against this T.Bond PE from 1960 to 2016:

| Download T Bond Rate PE data |
I also compute a ratio of stock PE to T.Bond PE that volition purpose equally a mensurate of relative stock marketplace pricing, amongst a depression value indicating that stocks are inexpensive (relative to T.Bonds) in addition to a high value suggesting the opposite. As you lot tin see, bringing inwards the depression treasury bond rates of the terminal decade into the analysis dramatically shifts the story delineate from stocks beingness over valued to stocks beingness nether valued. The ratio is equally 0.42 right now, good below the historical average over whatever of the fourth dimension periods listed, in addition to nowhere close the 1.91 that you lot saw inwards 2000, simply before the dot com bust or even the 1.04 simply before the 2008 crisis.
The erstwhile adage that it is cash flows, non earnings, that drives stocks is clearly beingness ignored when you lot await at whatever variant of PE ratios. To supply a feel of what stock prices await like, relative to cash flows, I computed a multiple of total cash returned to stockholders past times companies (including buybacks) in addition to compared these multiples to Shiller’s CAPE inwards the graph below:
 |
| S&P 500 Earnings in addition to Cash Payout |
Here again, at that spot seems to live a disconnect. While the CAPE has risen for the market, from 20.52 inwards 2009 to 27.27 inwards 2016, equally stocks soared during that period, the Price to CF ratio has remained stable over that catamenia (at nigh 20), reflecting the rising inwards cash returned past times US companies, primarily inwards buybacks over the period.
Am I making the representative that stocks are nether valued? If I did, I would live simply equally guilty equally those who purpose CAPE to brand the reverse case. I am non a marketplace timer, past times nature, in addition to whatever unmarried pricing metric, no thing how good reasoned it may be, is likewise weak to capture the complexity of the market. Absolutism inwards marketplace timing is a sign of either hubris or ignorance.
The Market’s Kryptonite
At this point, if you lot intend that I am sanguine nigh stocks, you lot would live wrong, since the essence of investing inwards equities is that worry goes amongst it. If it’s non the high CAPE that is worrying me, what is? Here are my biggest concerns, the kryptonite that could drain the marketplace of its strength in addition to vitality.
- The Treasury Alternative (or how much are you lot afraid of your key bank?) If the ground that you lot are inwards stocks is because the reward for beingness inwards bonds is low, that equation could alter if the bond reward improves. If you lot are Fed-watcher, convinced that key banks are all-powerful arbiters of involvement rates, your nightmares almost ever volition live related to a coming together of the Federal Open Market Committee (FOMC), in addition to inwards those nightmares, the Fed volition heighten rates from 1.50% to 4% on a whim, destroying your entire ground for investing inwards stocks. As I conduct hold noted inwards these before posts, where I conduct hold characterized the Fed equally the Wizard of Oz in addition to argued that low rates are to a greater extent than a reflection of depression inflation in addition to anemic growth than the termination of quantitative easing, I believe that whatever substantial charge per unit of measurement rises volition conduct hold to come upward from shifts inwards fundamentals, either an growth inwards inflation or a surge inwards existent growth. Both of these fundamentals volition play out inwards lucre equally well, pushing upward lucre growth in addition to making the stock marketplace effect ambiguous. In fact, I tin view a scenario where strong economical growth pushes T. bond rates upward to 3% or higher in addition to stock markets genuinely growth equally rates move up.
- The Earnings Hangover It is truthful that nosotros saw a long stint of lucre improvement later on the 2008 crisis in addition to that the stronger dollar in addition to a weaker global economic scheme are starting to crimp lucre levels in addition to growth. Earnings on the S&P 500 dropped inwards 2015 past times 11.08% in addition to are on a pathway to refuse over again this yr in addition to if the charge per unit of measurement of refuse accelerates, this could set stocks at risk. That said, you lot could brand the representative that the lucre refuse has been surprisingly muted, given multiple crises, in addition to that at that spot is no ground to fright a autumn off the cliff. No thing what your views, though, this volition live to a greater extent than probable to live a slow-motion correction, offering chances for investors to larn off the stock marketplace ride, if they thus desire.
- Cash flow Sustainability: My biggest concern, which I voiced at the start of the year, in addition to proceed to worry nigh is the sustainability of cash flows. Put bluntly, US companies cannot maintain returning cash at the charge per unit of measurement at which they are today in addition to the tabular array below provides the ground why:
| Year | Earnings | Dividends | Dividends + Buybacks | Dividend Payout | Cash Payout |
|---|---|---|---|---|---|
| 2001 | 38.85 | 15.74 | 30.08 | 40.52% | 77.43% |
| 2002 | 46.04 | 16.08 | 29.83 | 34.93% | 64.78% |
| 2003 | 54.69 | 17.88 | 31.58 | 32.69% | 57.74% |
| 2004 | 67.68 | 19.407 | 40.60 | 28.67% | 59.99% |
| 2005 | 76.45 | 22.38 | 61.17 | 29.27% | 80.01% |
| 2006 | 87.72 | 25.05 | 73.16 | 28.56% | 83.40% |
| 2007 | 82.54 | 27.73 | 95.36 | 33.60% | 115.53% |
| 2008 | 49.51 | 28.05 | 67.52 | 56.66% | 136.37% |
| 2009 | 56.86 | 22.31 | 37.43 | 39.24% | 65.82% |
| 2010 | 83.77 | 23.12 | 55.53 | 27.60% | 66.28% |
| 2011 | 96.44 | 26.02 | 71.28 | 26.98% | 73.91% |
| 2012 | 96.82 | 30.44 | 75.90 | 31.44% | 78.39% |
| 2013 | 107.3 | 36.28 | 88.13 | 33.81% | 82.13% |
| 2014 | 113.01 | 39.44 | 101.98 | 34.90% | 90.24% |
| 2015 | 100.48 | 43.16 | 106.10 | 42.95% | 105.59% |
| 2016 (LTM) | 98.61 | 43.88 | 110.62 | 44.50% | 112.18% |
So, how do these worries play out inwards my portfolio? They don’t explicitly but they do implicitly conduct upon my investment choices. I cannot do much nigh involvement rates, other than react, in addition to I volition remain ready, peculiarly if inflation pressures force upward rates in addition to the fixed income marketplace offers me a amend payoff. With lucre in addition to cash flows, at that spot may live concerns at the marketplace level, but I bet on private companies, non markets. With those companies, I tin do my due diligence to brand certain that they conduct hold the operating cash flows (not simply dividends or buybacks) to justify their valuations. If that sounds similar a pitch for intrinsic valuation, are you lot surprised?
The Market Timing Mirage
Will at that spot live a marketplace correction? Of course! When it does happen, don't live surprised to view a moving ridge of “I told you lot so” coming from the bubblers. H5N1 clock that is stuck at 12 o'clock volition live right twice every hateful solar daytime in addition to I would urge you lot to jurist these marketplace timers, non on their correction calls, which volition await prescient, but on their overall record. Many of them, later on all, conduct hold been suggesting that you lot remain out of stocks for the terminal v years or longer in addition to it would conduct hold to live a large correction for you lot to brand dorsum what you lot lost from staying on the sidelines. Some of these pundits volition live crowned equally bully marketplace timers past times the fiscal press in addition to they volition larn followers. I promise that I don’t audio similar a Cassandra but this much I know, from studying past times history. Most of these bully marketplace timers unremarkably larn it right once, allow that success larn to their heads in addition to proceed to allow their hubris drive them to to a greater extent than in addition to to a greater extent than extreme predictions inwards the side past times side cycle. As an investor, my proposition is that you lot salve your coin in addition to your sanity past times staying far away from marketplace prognosticators.
