Mairs & Power: Focused Investing For The Long-Term
Investing for the Long-Term
“The stock market is a highly efficient mechanism for the transfer of wealth from the impatient to the patient.” – Warren Buffett
There is no shortage of ideas about how to achieve investment success. The financial press, bloggers and books provide a continuing stream of opinions, theories and strategies, from the simple to the arcane. One often cited piece of street lore is to take advantage of the “January effect,” buying stocks at the start of the year when markets typically rise, while the flip side is captured in the expression ”sell in May and go away.” Another widespread practice, known as market timing, challenges investors to anticipate market swings as they rotate into defensive stocks when they expect the economy to slow, then move into growth stocks as they anticipate the start of a recovery. Still others chart technical patterns to reveal buy and sell signals. And the financial media, newsletters, commentators and bloggers fuel trading in stocks rumored to be takeover targets. Some investors are able to profit for a period of time following these and other trading strategies. However, as famed investor Warren Buffet indicated, investing to build wealth over time requires patience, discipline and consistency.
Researchers studying the markets over a long period of time have revealed a simple truth. The long-term patient investor consistently outperforms the impatient investor. Investment strategist and author Michael Mauboussin reviewed a select group of actively managed mutual funds that consistently beat the S&P 500 Index over a ten year period. He found that among their common attributes, the first was low turnover in portfolio holdings. He also cited a 1997 Morningstar Research study that found the lowest turnover mutual funds (turnover less than 20% per year) consistently outperformed higher turnover funds for 1-, 3-, 5- and 10- year periods. Mauboussin updated the research more than a decade later and found essentially the same results.
The remainder of this paper examines the reasons why long-term, low turnover investing outperforms other investing styles.
A Market Obsessed with the Short-Term
Wall St. Journal columnist Jason Zweig, among the many observers noting that the rate of buying and selling stocks has been rising for several decades, recently commented that “investors appear to be getting twitchier.” He reported that as recently as the year 2000, the average holding period for U.S. stocks was around two years. Today the average U.S. equity mutual fund reports more than 100% annual turnover, in effect selling the equivalent of every stock in the entire portfolio every 12 months.
Over the last several years, we have seen profound changes in the way markets operate, with significant implications for investors. The introduction of new investment vehicles such as Exchange Traded Funds (ETFs), and lightning-fast trading technologies have created an investment landscape where rapid buying and selling of entire baskets of stocks, wild price swings across whole markets and declining holding periods for individual equities now seem the norm. Zweig also noted that in 2014 the 20 largest ETFs traded at an average turnover rate of 1,244%, which translates into an average holding period of 29 days.
Holding stocks for less than a month can hardly be considered investing focused on earnings, dividends and balance sheets, since companies only report their progress via financial results once a quarter.
One of the most significant and visible changes over the past several years has been the rise of computer assisted high-frequency trading (HFT) where holding periods are measured in fractions of a second. This type of trading now drives the majority of trading volume in the global equity markets. In 2010, HFT was estimated to have accounted for 56% of the entire equity trading volume in the U.S., up from 21% in 2005. Today, HFT is estimated to account for as much as three-quarters of trading volume for the most highly liquid stocks.
While the emergence of high-frequency trading has increased the market’s short-term focus, it did not create that myopia. Many investors attempt to chase individual stocks, driven by headlines of quarterly earnings surprises, product announcements, merger and acquisition (M&A) activity or other business developments. In the current media-saturated global market, T.V. talking heads increase the volume of noise as they incessantly repeat rumors and fast-breaking news while the internet delivers minute-by-minute real time updates of portfolio value to distracted, headline-chasing investors. Other investors shift assets from one sector to another as financial and economic news such as interest rates, foreign exchange rates, Gross Domestic Product (GDP) growth, unemployment, consumer confidence and inflation affect the consensus outlook for different industries. In either approach, investors seek to profit essentially by trying to jump in front of an expected wave of buying or selling following the near instantaneous spread of financial news and market data with resulting high turnover of stocks. Economist John Maynard Keynes called this phenomena “forecasting the psychology of the market.”6 Compounding both headline chasing and market timing approaches, researchers have long observed “herding behavior” where large numbers of investors will mimic the trading activity of one another, magnifying the short-term impacts of trend chasing.
Growth of ‘Impatient Capital’ Creates Opportunities for Long-Terem Investing
To some, the idea of investing in the stock of a good company as a way to participate in the long-term success of the business may seem antiquated and out of place amidst this rapid fire buying and selling. While many observers lament the market’s obsession with short-term profits, immediate gratification and ‘now’ results, as investors we naturally ask ourselves: “Does this lopsided focus create an opportunity for long-term investors?” The answer is an emphatic ‘Yes!’ on several counts.
The data suggests that rapid trading and high turnover adds risks and costs without yielding better investment results. A study by Standard & Poor’s looking at every significant pullback in the S&P 500 Index since 1945 concluded that investors were better off riding out the market dips rather than trying to trade around them. The 59 pullbacks between 5% and 10% took one month on average for the decline to unfold and two months to recover to pre-decline levels. Of 19 market corrections between 10% and 20%, the decline occurred over five months on average and recovery occurred in four months. The twelve significant bear market declines (20% or more) took 14 months to reach bottom and 25 months, on average, to recover. So investors hoping to limit losses by selling into a decline during the more frequent shallow market pullbacks are likely to miss much of the upside recovery. They also risk having to buy back into the market at a higher level and will absorb increased transaction costs incurred in their in-and-out trading activity. While some studies do show higher trading activity can result in returns equivalent to lower turnover funds, those studies measure returns over periods from a month to a year, hardly a long-term investment horizon.
Many observers have pointed out that trying to time the market means an investor has to be right twice, both getting in and getting out of positions, but only has to be wrong once to turn impatience into a loss. Market timers also incur the added risk of
