General Portfolio Policy: The Defensive Investor
The basic characteristics of an investment portfolio are usually determined by the position and characteristics of the owner or owners. At one extreme we have had savings banks, life-insurance companies, and so-called legal trust funds. A generation ago their investments were limited by law in many states to high-grade bonds and, in some cases, high-grade preferred stocks. At the other extreme we have the well-to-do and experienced businessman, who will include any kind of bond or stock in his security list provided he considers it an attractive purchase.
It has been an old and sound principle that those who cannot afford to take risks should be content with a relatively low return on their invested funds. From this there has developed the general notion that the rate of return which the investor should aim for is more or less proportionate to the degree of risk he is ready to run. Our view is different. The rate of return sought should be dependent, rather, on the amount of intelligent effort the investor is willing and able to bring to bear on his task. The minimum return goes to our passive investor, who wants both safety and freedom from concern. The maximum return would be realized by the alert and enterprising investor who exercises maximum intelligence and skill. In 1965 we added: “In many cases there may be less real risk associated with buying a ‘bargain issue’ offering the chance of a large profit than with a conventional bond purchase yielding about 4½%.” This statement had more truth in it than we ourselves suspected, since in subsequent years even the best long-term bonds lost a substantial part of their market value because of the rise in interest rates.
The Basic Problem of Bond-Stock Allocation
We have already outlined in briefest form the portfolio policy of the defensive investor.* He should divide his funds between high-grade bonds and high-grade common stocks.
We have suggested as a fundamental guiding rule that the investor should never have less than 25% or more than 75% of his funds in common stocks, with a consequent inverse range of between 75% and 25% in bonds. There is an implication here that the standard division should be an equal one, or 50–50, between the two major investment mediums. According to tradition the sound reason for increasing the percentage in common stocks would be the appearance of the “bargain price” levels created in a protracted bear market. Conversely, sound procedure would call for reducing the common-stock component below 50% when in the judgment of the investor the market level has become dangerously high.
These copybook maxims have always been easy to enunciate and always difficult to follow—because they go against that very human nature which produces that excesses of bull and bear markets. It is almost a contradiction in terms to suggest as a feasible policy for the average stockowner that he lighten his holdings when the market advances beyond a certain point and add to them after a corresponding decline. It is because the average man operates, and apparently must operate, in opposite fashion that we have had the great advances and collapses of the past; and—this writer believes—we are likely to have them in the future.
If the division between investment and speculative operations were as clear now as once it was, we might be able to envisage investors as a shrewd, experienced group who sell out to the heedless, hapless speculators at high prices and buy back from them at depressed levels. This picture may have had some verisimilitude in bygone days, but it is hard to identify it with financial developments since 1949. There is no indication that such professional operations as those
