An extremely user-friendly overview of the inner workings of the US stock market. Things have changed a great deal since the heady days of the 1980s and we are now entering an era of profound uncertainty, with most analysts predicting trouble ahead. Indeed, the alarming decline of the NASDAQ shows no sign of abating and the fear is that traditional industries will be the next to bite the dust. September 11th has only added to the gloomy mood.
This book examines the current conditions before looking back to the events of the past century - The Great Depression, the 1970s oil crisis, the party-for-the-rich atmosphere of the 1980s and the emergence of the new economy.

1 The bubble era in US stocks

Introduction

When Gordon Gecko pronounced that greed is good’ in the movie ‘Wall Street’ he was probably half-right – but what he forgot to mention was that ‘fear is bad’. American investors not only listened to, but also believed, what Gordon Gecko (1988) stated

Greed, for the lack of a better word, is good. Greed is right. Greed works. Greed clarifies, cuts through and captures the essence of the evolutionary spirit. Greed in all its forms, greed for life, for money, for love, knowledge has marked the surge of mankind and greed, you mark my words, will not only save Teldar Paper but that other malfunctioning corporation called the USA.

There were primal motives at work in driving the explosion of US stock prices throughout the 1990s – whereby greed overwhelmed fear. If there was such a thing as investor fear it was of the wrong kind – the fear of missing out. Such an extended boom has not been matched anywhere in US financial history. Booms in stock prices have occurred before, particularly the golden years of the 1960s and not to mention the euphoric episode of 1928–9, but none quite like the extended run of the late 1990s. However, the stock boom of the 1990s was more than a boom – it resembled a bubble or a euphoria that caused a vast overvaluation of stock prices – that eventually had to burst. Moreover, the bubble was triple headed – as the US bond market and US dollar joined in the euphoria. Unfortunately, there have always been serious, if not devastating, collapses in real activity and job growth in the aftermath of a deflating bubble. Policy-makers and Greenspan in particular, were somewhat dubious of the run-up in US stock prices in the late 1990s as there was an inherent fear that a sudden collapse would cause much disruption to economic activity, human welfare and the retirement plans of ordinary US citizens. Just as the lives of ordinary people were damaged in the 1929 crash, so would a routing of US stock prices cause widespread damage across middle-class America. These fears were partially realized in 2000, as US stocks fell and then collapsed into a three-year bear market. The bursting of the US stock bubble, together with an out-of-favour US dollar, raised fear that a major protracted economic slowdown would follow. There are lessons from Japan’s burst bubble as Japan’s real economy languished for many years after the bubble deflated. We can go back further – just as in the Bible story – when Joseph proclaimed to Egypt that there would be seven fat years followed by seven lean years and so there is an apprehension that America’s euphoric bubble will have to be paid for’ with several lean years – consecutive or not.

This chapter is somewhat backward-looking in that it examines the major origins of the stock bubble. Brokerage houses pushed the historical fact that stocks have been a superior investment over most, if not all, other classes of assets over a long period of time. This is known as the equity premium puzzle. Hence, brokers pushed a ‘buy and hold strategy’ or more precisely a ‘buy and buy’ strategy. Wall Street was depicted as a one-way street and timing was not really that important – just buy and wait – according to the stock pushers. Or ‘buy on dips’ was another strong investment strategy. Another financial concept is also covered, namely Tobin’s Q ratio. When the value of the stock market soars, relative to corporate net worth there is an incentive for companies to invest in relatively cheap physical capital. This substitution effect eventually calls for lower stock prices and the Q ratio to mean revert. This ‘predictive tool’ pointed to a very high Q ratio in the bubble era that served as a warning signal for stock valuations to fall quite significantly. In essence, stocks trade within a corridor – albeit a wide corridor – and eventually self-correct. So we have two competing investment strategies: the buy and hold strategy (a one-way street) and the contrarian strategy (a two-way street) in Wall Street philosophy.

We now know that US stock markets came off their highs in 2000. We also know that such markets have been extremely volatile since 11 September 2001. What we do not know is how well the real economy will recover and whether corporate profits will improve significantly enough to lead a sustainable rally on Wall Street in 2005–6. Much depends on the ability of the real economy to self-correct – pulling stock prices along – or whether stock prices and stock returns mean revert to some kind of long-run average – that is well lower than the peaks of 1999.

By examining the super performance of US stocks this chapter lays the foundations for major analytical themes examined throughout this book.

Origins of the bubble

Just as Great Britain enjoyed a hundred and fifty years of world domination through technological and commercial superiority so has America achieved the same kind of hegemony over the last century. It is the vast accumulation of US wealth that has the latent power to destabilize financial markets and so the real economy, complicating the task of conducting an appropriate stabilization policy. Moreover, economic growth does not infer economic stability. Quite to the contrary, the trade-off between economic growth and macroeconomic stability is still alive and well, despite the high economic cruise speed of the United States in the 1990s. The US Federal Reserve has a mandate to fight inflation and maintain economic stability in an economic system that is prone to fluctuation or in layman’s terms – booms and busts. Why such booms and busts eventuate is still somewhat of a mystery, but the Federal Reserve has to make a value judgment as to whether it should smooth or minimize the effects of the ‘business cycle’. The irony of America’s massive wealth creation of the twentieth century has been associated with instability not only of output and employment but also of asset markets – and stock markets in particular. Speculation in asset markets, have their origins in some kind of monetary liquidity. That is, not just with expansions in the money supply, easy credit policies or margin lending but also with accumulated or stored wealth. It was America’s fat savings pool and vast amounts of capital searching for a home that caused much of its stock market bubble in the 1990s.

Just as Japan experienced a mammoth asset price bubble in the late 1980s due to its massive reserves of accumulated wealth (much of it from exports), so the United States witnessed an asset price bubble of a similar magnitude. The causes are complex, but the vast amount of funds stored in America by both nationals and foreigners is a major perpetrator of the recent asset price bubble. Below are a summary of forces.

Financial forces

• Rapid money supply growth/credit growth

• Foreign capital inflows

• Geopolitical forces

• Margin lending/financial leverage

• Low long-term interest rates

• Low inflation rates

• Lower risk premiums.

Behavioural forces

• Biased capital gain tax laws

• A preference for debt over equity

• Weak corporate governance

• Stock options

• Day trading

• Ponzi games.

Real forces

• Rapid productivity growth

• Expectations of productivity growth

• Expected earnings per share growth.

We shall examine the above causes of the bubble in some detail in Chapter 4. As outlined in this section there are three major driving forces to explain – liquidity, behavioural and real. There is a strong case for arguing that liquidity and behavioural forces dominated the rapid escalation of the stock prices far beyond that can be justified by real forces. The magnitude of this departure from real fundamentals is what a bubble is made of – superficial froth or euphoria – a substance that cannot support airborne stock prices over the long run.

Why the stock bubble?

Real fundamentals could not explain the explosion in US stock prices in the 1990s. Stock prices rose sixfold in this decade while labour productivity only doubled. This large escalation gap can be partially explained by investor behaviour in response to biased economic incentives – although some of this behaviour possessed no base but was indeed pure speculation. What remained as rational investor response was based on tax incentives, generous stock option packages for CEOs, corporate manipulation of profit results, low interest rates, low inflation rates and higher expected productivity growth.

However, financial forces have not been emphasized enough and these include the sizable capital flows into US stock and bond markets, the ‘dollar bubble’, geopolitical forces pushing funds into US markets, high levels of corporate financial leverage, margin lending for investors and the rapid growth in the money supply and credit.

A well-known author such as Schiller (2000) points to this escalation gap as being due to exuberance and behavioural forces that include speculation and greed. As in all bubbles these forces are plausible reasons but the fuel that ignites and allows the speculative fire to rage is that of excessive monetary liquidity and credit growth. Another respectable author such a Siegal (2000) points to changing and biased economic incentives such as the lower taxation of capital, lower risk premiums, a lower dividend payout ratio for holding stocks and lower transaction costs – so much so that stocks are a ‘one-way street’. This book emphasizes the significance of financial forces and foreign capital flows that caused much of the explosion in stock prices – above and beyond that can be explained by raw fundamentals. The remainder of the escalation in stock prices may be attributed to psychological and behavioural forces. It was abundant liquidity that fuelled the speculative fire.

Stocks versus bonds

Hindsight is God’s gift to the economist and so the world. I have just made Mark Haynes of CNBC Squawk Box so very happy! Over a long period of time, stocks have outperformed fixed interest investments. That is, despite wild fluctuations in stock prices and despite uncertainty associated with dividend payments, the rate of return from US stocks has been far higher than those from US fixed interest securities. Acceptance of higher risk derived higher returns from stocks than bonds. However, this superior performance is based on capital gains as well as dividends.

As can be seen from Figure 1.1, the trend line Dow performance (the dark line) has always rested above the nominal interest rate on the one-year treasury bill (T-Bill) – except for a brief period in 1981. Hence, a ‘buy and hold investor’ could effectively borrow funds and hold the Dow portfolio knowing that capital gains would be greater than the one-year T-Bill rate. Moreover, dividend payouts would accrue to such a conservative investor making the overall returns even greater. As will be discussed later, the ...
