Does asset inflation help support stock prices?

An anonymous comment on the preceding post has set me speculating further. The commentator says:

You are right, but I believe that this time around it will be equities, rather than commodities or real estate that will provide the hedge against coming inflation. Tobin's Q will prevail due to the juxtaposition of equity prices vs. the other two asset classes (which already had their surges) and the market's increasing valuation sophistication compared to the last time we saw hyperinflation in developed economies (i.e. the 1970s). So I've been buying stocks as an inflation hedge, despite the statistical evidence that this is foolish...

Wikipedia offers an explanation of Tobin's Q here. Essentially, Q is a measure of the relationship between the value of all a company's shares, and the value of the company's assets. If Q is greater than 1, there is some reason (real or imaginary) why the company has extra value to offer; if less than 1, a share investor could buy a company's underlying assets at a discount.

In 2006, Michael Alexander wrote a series of articles for Safe Haven, about stock cycles. Below, from the second in the series, is his graph for Q in several bear markets, including the one which he suggests began in 2000:

According to this, Q was already below 1 in 2006, and since the market is now back to about where it was a couple of years ago, that would suggest that shares are now fairly valued in relation to company assets.

But if history repeats itself, the current bear market has a long way to go, since the other three lasted 15 - 20 years. And in each of the previous cycles, Q slumped below 0.4.

Another complicating factor, thanks to the lending boom, is the real estate bubble. Steve Moyer is firmly of the opinion that real estate is very heavily overvalued, even now. So a collapse in that market would push Tobin's Q back up for many companies, a technical indication that share prices would have to drop steeply to get back to fair value (let alone overshoot to below Q=0.5).

In this context, it's worth noting that one of Mike Alexander's books, published in 2000, is titled "Stock Cycles: Why stocks won't beat money markets over the next twenty years".

Why the sea is salt, and why we are drowning in cash

We are said to be heading for a recession, so I had another look at Bank of England statistics for M4 - money supply as measured by private lending by financial institutions.

Since June 1963, there has NEVER been a quarterly period when M4 contracted. In fact, here are the only times in the last 44 years when UK quarterly monetary inflation ran at less than 5% p.a. equivalent:

As you see, mostly it was the nineties, with one instance in 1975 and three times in the sixties. The average rate for the whole series up to December 2006 is 13.47%. So the hand-mill never stops grinding.

But should it? Wikipedia gives an account of recession and the Great American Depression, and notes that during the latter period the money supply contracted by a third. Great for money-holders, bad for the economy and jobs.

This page points out that we tend (wrongly) to think of a period of economic slowdown as a recession, and says that technically, recession is defined as two successive quarters of negative economic growth. By that measure, we haven't had a recession in the UK (unlike Germany) for about 15 years - here's a graph of the last few years (source):

And then there's the stockmarket. It doesn't seem to reflect the real state of the economy - until you shift the lines, when for example the S&P 500 turns out to be a fair predictor of changes in GDP, as shown in a graph in a 2005 entry from this blog ("Capital Chronicle", by RJH Adams):

The same post also provides a brilliant graph of a measure of fair value for investors, known as Tobin's Q. Look at the wonderful opportunities presented by two world wars and the economic shock (blamed on oil prices, but maybe the causality is the wrong way round) of the 70s:

Mind you, looking at Wikipedia's Tobin's Q graph, the median market valuation since 1900 seems to be something like only 70% of the worth of a company's assets. Can that be right? Or should we take the short-sighted view of some accountants and sell off everything that might show a quick profit?

Nevertheless, it still feels to me (yes, "finance with feeling", I'm afraid) as though the markets are over-high, even after taking account of the effects of monetary inflation on the price of shares. And debt has mounted up so far that a cutback by consumers could be what finally makes the economy turn down. Not just American consumers: here is a Daily Telegraph article from August 24th, stating that for the first time, personal borrowing in the UK has exceeded GDP.

The big question, asked so often now, is whether determined grinding-out of money and credit can stave off a vicious contraction like that of the Great Depression. Many commentators point out that although interest rates are declining again, the actual interest charged to the public is not falling - lenders are using the difference to cover what they perceive as increased risk. Maybe further interest rate cuts will be used in the same way and keep the lenders willing to finance the status quo.

Some might say that this perpetuates the financial irresponsibility of governments and consumers, but sometimes it's better to defer the "proper sorting-out" demanded by economic purists and zealots. History suggests it: in the 16th century, if Elizabeth I had listened to one party or another in Parliament, we'd have thrown in our lot with either France or Spain - and been drawn into a major war with the other. We sidestepped the worst effects of the Thirty Years' War, and even benefited from an influx of skilled workers fleeing the chaos on the Continent. If only we could have prevented the clash of authoritarians and rebellious Puritans for long enough, maybe we'd have avoided the Civil War, too.

So perhaps we shouldn't be quite so unyielding in our criticisms of central bankers who try to fudge their - and our - way out of total disaster.
