Predicting market

The latest research in financial economics seems to confirm that markets are not strictly efficient and that there are pockets of predictability. This offers some hope to "disciplined" active managers if they can come up with innovative techniques to achieve superior long-term returns

But it is very important for any investor to watch closely for changing market drivers. For example, the market drivers until late 1998 were easy credit, moderating inflation, lower interest rates, rising earnings and the wide publicity of nearly an eighteen-year bull market in equities by some counts, a fifty-year bull market. The 1990s have seen a 16% compounded rate of growth for equities versus 6% historically, so it is not surprising that strong momentum keeps everyone in the game.

But we are beginning to face a different set of market drivers and it is hard to tell where they will drive us. The kind of financial concerns we face are rather novel in all of our lifetimes. There is illiquidity; wealth has been destroyed in many parts of the world; and inflation has turned to disinflation, to lower inflation and now to deflation. Deflation is destructive, especially for debt, which has led to a quality preference on debt where only the highest quality can pass muster and the ability to borrow is probably the only thing that counts in analyzing securities (see Value Investing).

What about the impact of news on portfolio management decisions? It is worth noting that precisely the same evidence may be used to support a good market tone or a bad market tone a bull market or a bear market. For example, the absence of rising prices could be good for continued growth and low unemployment, or it could be bad because deflationary forces are building up and, as the experience of Japan indicates, they are extremely destabilizing. Interest rates are attractive for borrowing and money is plentiful, which is very good for business; but it may well be bad because it means that a great deal of money is flowing in from overseas to the United States as the last fortress of capital.

Similarly, the public continues to buy IPOs (see Initial Public Offerings), almost every single one. Is that good because it means confidence or bad because it means that there is such a strong psychological undertone to the market that when it cracks, nothing will bring it back? What is more, the quality stocks have done much better for the last several years than the broad market averages. Good because it suggests leadership? Or bad, meaning that there really is a low level of confidence, and this is just speculation in well-known names?

Also, we have continued concerns about what will happen in the year 2000 with our computer systems. Good if nothing happens or bad because the year 2000 is only months away? Finally, earnings are good, but on the other hand, the majority of the surprises are on the downside: there appears to be a deterioration in terms of buildup of disappointments. So the same news can be seen as good or bad.
