Anthony Hilton: What is the stock market for? Mainly enriching traders and middle men

Vince Cable was told that no new capital had been raised in the stock market for 20 years

Economics textbooks tell you that the purpose of a stock market is to channel savings into productive business. It may indeed have worked like that back in Victorian times, but it is not how it works today. At a dinner on Wednesday night sponsored by the law firm Evershed's, Professor John Kay, who has made a study of the functioning of the markets at the request of the Business Secretary, Vince Cable, below, pointed out that there has been no net new capital raised in the stock market in the last 20 years.

There had been some new issues where the founder of a business wants to get cash out, and there had been some rights issues to provide new capital for businesses which had got into difficulties. But this and other new money was more than offset by the shrinkage elsewhere caused by companies being taken over, or going bust, or of others buying back their own shares rather than investing to grow their businesses. Separately, lending support to what he says, the National Association of Pension Funds recently provided figures to show that only 15 per cent of the new money saved by its members was being channelled into the UK equity market. The rest was going into bonds or overseas.

But if the stock market is no longer raising capital for business, what is it for? In theory it allows investors to become shareholders in existing businesses and share in their profits. But this does not work either, because as Professor Kay further pointed out, the vast bulk of those profits are creamed off by an army of intermediaries: fund managers, brokers, independent financial advisers, investment consultants, platform providers, custodians and a string of others. They make a comfortable living, but the investor rarely does. Indeed, others have calculated that private pension plan returns would be a third higher if only the fund managers charged at the same rate they do in Holland.

And the other market participants are traders, using computers to buy and sell within a millionth of a second so they can exploit the most minor and shortlived movements in prices. Again, they make a comfortable living. Again, it is hard to see what value they add, or how they further the primary purpose of the market. Arguably they work against it by adding to the volatility which scares off ordinary people.

Market professionals have different priorities from ordinary investors, which is why the pressure on companies is for short-term results. This means executives will cut back on research and development, think twice about making big investments which won't deliver an immediate pay-off, and will sell or close down underperforming businesses rather than spend time trying to turn them round. If you want to know why the British economy is unbalanced, then this is at least part of the reason. The financial tail wags the dog.

Unfortunately, though great on diagnosis, Professor Kay can't think of any short-term fix. The only real hope, he says, is for investors and pension fund trustees to wise up to what is happening, understand how it is not in their interests and demand a change in City behaviour. It is a long-term project.

Meanwhile, what is the purpose of the stock market? Professor Kay pauses and then says that perhaps its main role today is to lay down and enforce good corporate governance.
