My father, Edward Cady Marsh, was a Wall Street investment banker. He took the train in to Wall Street each morning from Westfield, New Jersey and returned in the late afternoon. He specialized in industries such as the automobile industry, the steel industry, and the grocery industry. His compensation was based in part on his recommendations to the board, regardless of whether the board accepted and acted on his recommendations. As someone who lived through the stock market exuberance of the late 1920s and the crash and depression thereafter, he was very aware of the downside of stock market investing.

I learned early on that the profitability of a company was only one aspect to consider. The stock’s price was of equal importance. Overpaying for a very profitable company’s stock could be just as big a mistake as buying a cheap stock that had poor profitability prospects. Another factor that retail investors often overlook is the time horizon of stock market pricing. My own experience suggests that the typical stock is evaluated on a six month return basis. In other words, on average the market appears to be pricing stocks on the basis of how well they are expected to perform in six months. After the Great Recession the stock market bottomed out in March of 2009, but the economy took about six months before it was clearly heading up again.

If you get into a great stock too early, your investment may just flounder around rising and falling without much direction before it finally takes off, whenever that might be. Getting in to a good stock too early can be just as bad as getting in too late after its price to earnings ratio has reached unrealistic levels.

Another common mistake made by retail investors is sitting on too much cash and not investing for fear of short term losses. The general pattern of the stock market is to fluctuate up and down for some time and occasionally slip into a bear market, but, more importantly, suddenly move upward to establish a new level. It is these sudden upward moves, when you have too much of your investable funds in cash, that can make stock investing unprofitable. Many studies have pointed out that missing out on just of couple days of extraordinary gains in a very profitable year can eliminate most of the profit.

For the retail investor, investing in individual stocks can be very dangerous. Although most stocks tend to move up and down with the market over the short run, individual stocks can drop dramatically or move up unexpectedly. For the retail investor, investing in individual stocks is more akin to gambling that investing. As a retail investor, I have benefited from investing in broad market index funds with very low expense fees. Professional investors are much better positioned to determine which stocks are best to invest in at a particular price and time. However, sorting out the good professional investors from the bad and overcoming the fees charged by professional investors might not be worth the time and trouble. Index funds with low fees can sometimes be more cost effective and efficient than actively managed funds.

Clearly there are trends that may signal substantial increases in profitability going forward. A professional investor might consider whether the time is right to invest in stocks of companies producing lithium in anticipation of a big increase in the sales of electric vehicles that require lithium batteries. But what if there is a breakthrough in battery technology that replaces lithium with some other ingredient? In that case, the value of lithium stocks could drop dramatically.

Individualized medicine is another area ripe for expansion in coming years. Most of our doctors do not even have a sample of our DNA. Moreover, the randomized trials compare the average person’s response in the experimental condition with the average person’s response in the control condition to determine the statistical significance of the average person’s response to a drug or other medical intervention. But if the distribution is bimodal with half the people at one end and the other half at the other end, the average person may not exist. With more and more individualized data becoming more widely available, a professional investor may want to consider investing in companies with personalized medical data (e.g., DNA) that are able to zoom in to subsets of individuals sharing common characteristics to get closer to the uniqueness of an individual patient in order to provide individualized diagnosis and prognosis. For the retail investor these potential breakthroughs may introduce too much uncertainly and potential volatility but may be of interest to the professional investor.

Finally, one might consider the use of leveraged funds. Such funds provide multiples of the price movements of their corresponding indices either in the same direction (leveraged longs, UDOW) or in the opposite direction (leveraged shorts, SDOW). The opposite strategy would be to seek out the least volatile stock indices which tend to the ones that emphasize dividends. One approach might be to move from a broad based stock index fund into a fund emphasizing dividends when the stock market seems overextended in an irrational exuberance phase. If one is really into gambling, substituting broad-market leveraged shorts would be an alternative strategy at such times. On the other hand, when the stock prices have fallen significantly, one could move into broad-market leveraged longs, which could dramatically increase yields when (and if) the market recovers. Note that the expense ratios for these leveraged funds tend to be quite high and may be restricted to accredited investors.

In general, successful stock market investing requires being reasonably cautious and very patient. Most importantly, the investors style and strategy must match their personality. What works for one person may be entirely inappropriate for someone else. If you become distraught and tear your hair out when your portfolio’s value drops with a market decline, including a bear market that lasts for some time, then your style and strategy do not match your personality.
