With worries about Greek exit from the eurozone, with the unlikelihood of further quantitative easing in the USA and the UK, with interest rates likely to rise in the medium term, and with Chinese growth predicted to be more moderate, many market analysts are forecasting that stock markets are likely to fall in the near future. Indeed, markets are already down over the past few weeks. Since late April/early May, the FTSE is down 4.5%; the German DAX index is down 7.0%; the French CAC40 index is down 6.9%; and the US Dow Jones index is down 2.3%. But does this give us an indication of what is likely to happen over the coming months?
If stock markets were perfectly efficient, then all possible information about the future will already have been taken into account and will all be reflected in current share prices. It would be impossible to ‘get ahead of the game’.
It is only if market participants have imperfect information and if you have better information than other people that you can are likely to predict correctly what will happen. Even then, the markets might be buffeted by random and hence unpredictable shocks.
Some people correctly predicted things in the past: such as crashes or booms. But in many cases, this was luck and their subsequent predictions have proved to be wrong. When financial advisers or newspaper columnists give advice, they are often wrong. If they were reliably right, then people would follow their advice and markets would rapidly adjust to their predictions.
If Greece were definitely to exit the euro, if interest rates were definitely to rise in the near future, if it became generally believed that stock markets were overvalued, then stock markets would probably fall. But these things may not happen. After all, people have been predicting a rise in interest rates from their ultra-low levels for many months – and it hasn’t happened yet, and may not happen for some time to come – but it may!
If you want to buy shares, you might just as well buy them at random – or randomly sell any you already have. As Tetlock says, quoted in the Nasdaq article:
“Even the most astute observers will fail to outperform random prediction generators – the functional equivalent of dart-throwing chimps.”
And yet, people do believe that they can predict what is going to happen to stock markets – if not precisely, then at least roughly. Are they deluded, or can looking calmly at likely political and economic events put them one step ahead of other people who perhaps behave more reactively and emotionally?

Questions
- Why may a return of rising interest rates lead to a ‘meltdown in equity prices’? Why might it not?
- Why have bond yields fallen dramatically since 2008?
- Why are bond yields rising again now and what significance might this have (or have had) for equity markets?
- Why may following the crowd often lead to buying high and selling low?
- Is there an asymmetry between buying and selling behaviour in stock markets?
- Will ignoring stock market forecasts make people better investors?
- “The stock market prices suggest that investors believe both the Federal Reserve and the Bank of England are bluffing about raising interest rates. That may be so, but it is an extremely risky game of chicken for investors to play.” Explain and discuss.
You may have been following the posts on the US debt ceiling and budget crisis: Over the cliff and Over the cliff: an update. Well, after considerable brinkmanship over the past couple of weeks, and with the government in partial shutdown since 1 October thanks to no budget being passed, a deal was finally agreed by both Houses of Congress, less than 12 hours before the deadline of 17 October. This is the date when the USA would have bumped up against the debt ceiling of $16.699 trillion and would be in default – unable to borrow sufficient funds to pay its bills, including maturing debt.
But the deal only delays the problem of a deeply divided Congress, with the Republican majority on the House of Representatives only willing to make a long-term agreement in exchange for concessions by President Obama and the Democrats on the healthcare reform legislation. All that has been agreed is to suspend the debt ceiling until 7 February 2014 and fund government until 15 January 2014.
A more permanent solution is clearly needed: not just one that raises the debt ceiling before the next deadline, but one which avoids such problems in the future. Such concerns were echoed by Christine Lagarde, Managing Director of the International Monetary Fund (IMF), who issued the following statement:
The U.S. Congress has taken an important and necessary step by ending the partial shutdown of the federal government and lifting the debt ceiling, which enables the government to continue its operations without disruption for the next few months while budget negotiations continue to unfold.
It will be essential to reduce uncertainty surrounding the conduct of fiscal policy by raising the debt limit in a more durable manner. We also continue to encourage the U.S. to approve a budget for 2014 and replace the sequester with gradually phased-in measures that would not harm the recovery, and to adopt a balanced and comprehensive medium-term fiscal plan.

- Is the agreement of October 16 likely to ‘reassure markets’? Explain your reasoning.
- What is likely to happen to long-term interest rates as a result of the agreement?
- Will the imposition of a new debt ceiling by February 2014 remove the possibility of using fiscal policy to stimulate aggregate demand and speed up the recovery?

The rate of growth in India has fallen to its lowest level since the first three months of 2009 – the period when many countries were plunging into recession. Although the annual rate was still 4.4% in Q2 2013 (a rate most Western governments would love to achieve!), it had averaged 8.2% from 2003 to 2007 and 9.5% from 2010 to 2011 (see).
And the rupee has been falling in value (see chart below). The exchange rate of the rupee to the dollar has depreciated by 21% since the start of the year and by 14% since the beginning of August (click here for a PowerPoint of the chart). This has pushed up the price of imports and raised fears that inflation, already approaching 10%, will rise.
There have also been concerns about the health of India’s banking sector, with worries over the possible rise in bad loans.
One result of all these factors is that the confidence of investors has been shaken. Bond prices have fallen and so too have share prices. The Mumbai Sensex index fell by 11.5% from 22 July to 27 August. Worried about possible capital flight, the Indian government imposed capital controls on Indian residents on 14 August. It has, however, since ruled out limiting the outflow of funds by foreign investors.
The following articles and videos look at the causes of the current economic problems and what can be done about them.

Each day many investors anxiously watch the stock market to see if their shares have gone up or down. They may also speculate: buying if they think share prices are likely to go up; selling if they think their shares will fall. But what drives these expectations?
To some extent, people will look at real factors, such as company sales and profits or macroeconomic indicators, such as the rate of economic growth or changes in public-sector borrowing. But to a large extent people are trying to predict what other people will do: how other people will react to changes in various indicators.
John Maynard Keynes observed this phenomenon in Chapter 12 of his General Theory of Employment, Interest and Money of 1936. He likened this process of anticipating what other people will do to a newspaper beauty contest, popular at the time. In fact, behaviour of this kind has become known as a Keynesian beauty contest (see also).
Keynes wrote that:
professional investment may be likened to those newspaper competitions in which the competitors have to pick out the six prettiest faces from a hundred photographs, the prize being awarded to the competitor whose choice most nearly corresponds to the average preferences of the competitors as a whole; so that each competitor has to pick, not those faces which he himself finds prettiest, but those which he thinks likeliest to catch the fancy of the other competitors, all of whom are looking at the problem from the same point of view. It is not a case of choosing those which, to the best of one’s judgement, are really the prettiest, nor even those which average opinion genuinely thinks the prettiest. We have reached the third degree where we devote our intelligences to anticipating what average opinion expects the average opinion to be. And there are some, I believe, who practise the fourth, fifth and higher degrees.
When investors focus on people’s likely reactions, it can make markets very unstable. A relatively minor piece of news can cause people to buy or sell in anticipation that others will do the same and that others will realise this and do the same themselves. Markets can overshoot, until, when prices have got out of line with fundamentals, buying can turn into selling, or vice versa. Prices can then move rapidly in the other direction, again driven by what people think other people will do. Sometimes, markets can react to very trivial news indeed. As the New York Times article below states:
On days without much news, the market is simply reacting to itself. And because anxiety is running high, investors make quick, sometimes impulsive, responses to relatively minor events.
The rise of the machine
In recent years there is a new factor to account for growing stock market volatility. The Keynesian beauty contest is increasingly being played by computers. They are programmed to buy and sell when certain conditions are met. The hundreds of human traders of the past who packed trading floors of stock markets, have been largely replaced by just a few programmers, trained to adjust the algorithms of the computers their finance companies use as trading conditions change.
And these computers react in milliseconds to what other computers are doing, which in turn react to what others are doing. Markets can, as a result, suddenly soar or plummet, until the algorithms kick the market into reverse as computers sell over-priced stock or buy under-priced stock, which triggers other computers to do the same.
Robot trading is here to stay. The articles and podcast consider the implications of the ‘games’ they are playing – for savers, companies and the economy.

Since the beginning of 2009, central banks around the world have operated an extremely loose monetary policy. Their interest rates have been close to zero (click here for a PowerPoint of the chart) and more than $20 trillion of extra money has been injected into the world economy through various programmes of quantitative easing.
The most recent example of loose monetary policy has been in Japan, where substantial quantitative easing has been the first of Japan’s three arrows to revive the economy (the other two being fiscal policy and supply-side policy).
One consequence of a rise in money supply has been the purchase of a range of financial assets, including shares, bonds and commodities. As a result, despite the sluggish or negative growth in most developed countries, stock markets have soared (see chart). From March 2009 to May 2013, the FTSE 100 rose by 91% and both the USA’s Dow Jones Industrial average and Germany’s DAX rose by 129%. Japan’s NIKKEI 225, while changing little from 2009 to 2012, rose by 78% from November 2012 to May 2013 (click here for a PowerPoint of the chart).
The US economy has been showing stronger growth in recent months and, as a result, the Fed has indicated that it may soon have to begin tightening monetary policy. It is not doing so yet, nor are other central banks, but the concern that this may happen in the medium term has been enough to persuade many investors that stock markets are likely to fall as money eventually becomes tighter. Given the high degree of speculation on stock markets, this has led to a large-scale selling of shares as investors try to ‘get ahead of the curve’.
From mid-May to mid-June, the FTSE 100 fell by 6.2%, the Dow Jones by 2.6%, the DAX by 4.5% and the NIKKEI by 15%. In some developing countries, the falls have been steeper as the cheap money that entered their economies in search of higher returns has been leaving. The falls in their stock markets have been accompanied by falls in their exchange rates.
The core of the problem is that most of the extra money that was created by central banks has been used for asset purchase, rather than in financing extra consumer expenditure or capital investment. If money is tightened, it is possible that not only will stock and bond markets fall, but the fragile recovery may be stifled. In other words, tighter money and higher interest rates may indeed affect the real economy, even though loose monetary policy and record low interest rates had only a very modest effect on the real economy.
This poses a very difficult question for central banks. If even the possibility of monetary tightening some time in the future has spooked markets and may rebound on the real economy, does that compel central banks to maintain their loose policy? If it does, will this create an even bigger adjustment problem in the future? Or could there be a ‘soft landing’, whereby real growth absorbs the extra money and gradually eases the inflationary pressure on asset markets?
