Charles Dow Quotes

Pride of opinion has been responsible for the downfall of more men on Wall Street than any other factor.

Many have been supposedly foolproof but zany formulae that have made no one rich but the hucksters who sold them to the gullible. But over the years there have been some approaches that have enjoyed at least a modicum of success. These range from the Dow Theory first espoused by Wall Street Journal founder Charles Dow—essentially using technical indicators to try to identify and profit from different market phases—and David Butler’s CANSLIM system, to the value investing school articulated by Benjamin Graham. The earth-shattering suggestion of the research conducted in the 1960s and 1970s was that the code might actually be unbreakable, and efforts to decipher it were expensive and futile. Harry Markowitz’s modern portfolio theory and William Sharpe’s CAPM indicated that the market itself was the optimal balance between risks and return, while Gene Fama presented a cohesive, compelling argument for why that was: The net effect of the efforts of thousands upon thousands of investors continually trying to outsmart each other was that the stock market was efficient, and in practice hard to beat. Most investors should therefore just sit on their hands and buy the entire market. But in the 1980s and 1990s, a new round of groundbreaking research—some of it from the same efficient-markets disciples who had rattled the investing world in the 1960s and 1970s—started revealing some fault lines in the academic edifice built up in the previous decades. Perhaps the stock market wasn’t entirely efficient, and maybe there were indeed ways to beat it in the long run? Some gremlins in the system were always known, but often glossed over. Already in the early 1970s, Black and Scholes had noted that there were some odd issues with the theory, such as how less volatile stocks actually produced better long-term returns than choppier ones. That contradicted the belief that return and risk (using volatility as a proxy for risk) were correlated. In other words, loopier roller coasters produce greater thrills. Though the theory made intuitive sense, in practice it didn’t seem to hold up to rigorous scrutiny. This is why Scholes and Black initially proposed that Wells Fargo should set up a fund that would buy lower-volatility stocks (that is, low-beta) and use leverage to bring the portfolio’s overall volatility up to the broader stock market.7 Hey, presto, a roller coaster with the same number of loops as everyone else, but with even greater thrills. Nonetheless, the efficient-markets hypothesis quickly became dogma at business schools around the United States.

Remember you are not alone. The disciples forgot this one simple truth and detonated a landmine of fear. Out on the open Sea of Galilee with storm clouds gathering, they became fearful. Their eyes were set on their physical surroundings. Instead of recalling the promises of God, they cried out, believing their lives were about to end. So many times we immediately think, Oh, no! What if this happens? What will I do?We cave

I have never known a great trader, with his first reputation established as a bear operator, who did not either turn bull or drop out of the market altogether.

Standard & Poor’s Dow Jones Indices published a statistical analysis in 2016 detailing the dismal record of “active” portfolio managers: As is typically the case, about two-thirds of active large-capitalization managers underperformed the S&P 500 large-cap index during 2015. Nor
