prices relative to earnings already are above or below traditional norms. Interest rate trends also influence stock prices significantly. Rising interest rates tend to depress stock prices -- partly because they can foreshadow a general slowdown in economic activity and corporate profits, and partly because they lure investors out of the stock market and into new issues of interest-bearing investments. Falling rates, conversely, often lead to higher stock prices, both because they suggest easier borrowing and faster growth, and because they make new interest-paying investments less attractive to investors. A number of other factors complicate matters, however. For one thing, investors generally buy stocks according to their expectations about the unpredictable future, not according to current earnings. Expectations can be influenced by a variety of factors, many of them not necessarily rational or justified. As a result, the short-term connection between prices and earnings can be tenuous.
