There is overwhelming and consistent evidence, both statistical and anecdotal, that a synchronized global economic expansion is underway, which most probably is still in its early innings. Virtually all developed and emerging economies are participating. This is helping corporations around the world to begin to achieve meaningful revenue growth and a leveraged improvement in profits. This is especially true for those companies which have spent the last several years cutting costs and disposing of non-core businesses.
This memo is an attempt to measure the impact on U.S. equity prices over the intermediate term and to point out the danger signals that would precede the end of this expansion, which would most likely trigger a significant correction in equity prices. We see few signs that such a development is even on the horizon, so this is merely a road map for the future.
So far this year, the S&P 500 Stock Index has gained 15%, excluding dividends. Yet, the forward P/E ratio of the Index, looking four quarters ahead, has not increased very much since consensus forward profit estimates have been marked up each quarter. At the beginning of this year, consensus estimates for this index called for earnings of about $125, leading to a forward P/E of approximately 18X. The consensus for the year has now moved up to $135, which implies a P/E of 19X, equivalent to an earnings yield of 5.2%, which compares favorably with the current BBB bond yield of 4.3%. Even this overstates the current valuation of equities because profits in the 4th quarter of this year are likely to achieve an annual rate of more than $140 per share, and preliminary indications suggest that if the expansion continues at its current pace, even without a corporate tax cut, earnings one year out could reach $150, which puts the forward P/E back to 17X, equivalent to a 5.8% earnings yield.
U.S. corporations, particularly our multinationals, are ideally positioned to benefit from global expansion, due to our leadership in many industries, particularly high tech, as well as our increasingly favorable cost structures and a relatively soft U.S. dollar relative to the Euro and the Yen. The latter is a boon to our export earnings and also to the translation of foreign source earnings back into dollars as it magnifies the Dollar based earnings per share. In addition, because there is still ample excess capacity both here and abroad, U.S. companies are generating cash flow well-above their needs for working capital and plant expansion or modernization. Much of this surplus is being returned to shareholders in the form of stock buybacks and dividend increases.
However, it is important to note that neither extremes of high nor low equity valuations by themselves will determine the course of stock prices going forward. That will depend on the degree and trend of financial market liquidity. To gauge current liquidity conditions, we track a number of metrics.
First, there is the growth rate of broad money supply (M2), which we compare with the growth of nominal GDP. So far in 2017, M2 has increased just about 5.0% year on year, but Nominal GDP in the U.S. is up only about 4.1%, year on year, which implies a surplus of money supply, which inevitably finds it way into financial asset markets, including bonds, equities and real estate. A more sensitive measure compares the growth rate of money supply with the growth rate of bank loans. Against the 5.0% rate of growth of M2 so far this year, bank loans are up only 3.6% year on year. Admittedly, loan growth has accelerated over the past seven months to a 5.8% annual rate. Ergo, this relationship will bear careful watching. If inflation were to pick up noticeably, it would have to be financed, and if money is required to finance inventories, receivables and capital expenditures, that would tighten the system. However, in a world of floating exchange rates, money is fungible and as long as the central banks of the U.S., Great Britain, Japan and the ECB are growing money supply faster than global GDP, financial system liquidity is unlikely to tighten enough to impact equity prices.
There are other market-based indicators which offer real-time insights into financial market conditions. Among these is the yield spread between 10-year U.S. Treasuries, currently at 2.33%, minus the yield on the 2-year note of 1.62%. This leaves a positive spread currently of 71 basis points, still a long way from an inverted yield curve. If an overheated economy, coupled with rising inflation, caused the yield curve to invert, clearly that would be a danger signal. At this point, however, given global excess capacity, technological innovation and various corporate disrupters (e.g., Amazon), as well as demographic factors, all keeping a lid on pricing power, there are no inflation warning signs yet visible. Finally, we take note of various credit spreads, including high-yield over seven year Treasuries, or BAA spreads over Treasuries, as well as indicators of global short rates. None of these suggests any tightening of financial conditions at this time.
The bottom line is that at some point in the future, history suggests the U.S. economy will overheat. As growth exceeds potential (defined as labor force growth plus productivity growth), inflation will rise and the Federal Reserve Board will be forced to tighten monetary policy more aggressively than what the FOMC has indicated recently is its policy of gradually reducing monetary accommodation. At that point, the risk of recession will rise substantially and a resulting decline in stock prices could be exacerbated by the liquidation of ETFs, which have become a multi-trillion dollar factor in the $27 trillion U.S. equity market.
