One of the aspects of the market that is most likely to confuse investors here is the wide range of opinions about valuation, with some analysts arguing that stocks are cheap or fairly valued, and others - including Jeremy Grantham, Albert Edwards, and of course us - arguing that valuations are very rich.
The following chart may help to bridge that gulf. Essentially, analysts who view stocks as "cheap" here are invariably basing that conclusion on current and year-ahead forecasts for earnings. In contrast, analysts who view stocks as richly valued are typically those who view stocks as a claim not on this years' or next years' earnings, but instead are a claim on a long-term stream of deliverable cash flows. Simply put, there is presently a massive difference between short-horizon earnings measures and longer-term, normalized earnings measures.
What's going on here is that profit margins have never been wider in history. But profit margins are also highly cyclical over time. The wide margins at present are partly the result of deficit spending amounting to more than 8% of GDP - where government transfer payments are still holding up nearly 20% of total consumer spending, and partly the result of foreign labor outsourcing (directly, and also indirectly through imported intermediate goods) which has held down wage and salary payouts. Indeed, the ratio of corporate profits to GDP is now close to 70% above its long-term norm.
Now, if you look at the red line (right scale, inverted), you'll notice that unusually high profit shares are invariably correlated with unusually low growth in corporate profits over the following 5-year period. Thanks to continuing deficits and extraordinary monetary interventions, this effect has been largely postponed in recent years, allowing profits to expand to present extremes. We are not arguing that profit margins necessarily have to decline over the near-term, and our concerns don't rest on the assumption that they will. It is sufficient to recognize that the bulk of the value of any stock is not in the early years of earnings, but in the long tail of future cash flows - especially if payouts are low. Stocks are essentially 50-year instruments here in terms of the cash flows that are relevant to their valuation. There are a lot of factors and quiet math that affect the P/E multiple that can be appropriately applied to earnings. Slapping an arbitrary multiple onto elevated earnings reflecting extraordinarily inflated profit margins ignores all of it.
