I once had a foreign exchange trader who worked for me who was an unabashed chartist. He truly believed that all the information you needed was reflected in the past history of a currency. Now it's true there can be less to consider in trading currencies than individual equities, since at least for developed country currencies it's typically not necessary to pore over their financial statements every quarter. And in my experience, currencies do exhibit sustainable trends more reliably than, say, bonds or commodities. Imbalances caused by, for example, interest rate differentials that favor one currency over another (by making it more profitable to invest in the higher-yielding one) can persist for years. Of course, another appeal of charting can be that it provides a convenient excuse to avoid having to analyze financial statements or other fundamental data. Technical analysts take their work seriously and apply themselves to it diligently, but it's also possible for a part-time technician to do his market analysis in ten minutes over coffee and a bagel. This can create the false illusion of being a very efficient worker. The FX trader I mentioned was quite happy to engage in an experiment whereby he did the trades recommended by our in-house market technician. Both shared the same commitment to charts as an under-appreciated path to market success, a belief clearly at odds with the in-house technician's avoidance of trading any actual positions so as to provide empirical proof of his insights with trading profits. When challenged, he invariably countered that managing trading positions would challenge his objectivity, as if holding a losing position would induce him to continue recommending it in spite of the chart's contrary insight. But then, why hold a losing position if it's not what the chart said? I always found debating such tortured logic a brief but entertaining use of time when lining up to get lunch in the trader's cafeteria. To the surprise of my FX trader if not to me, the technical analysis trading account was unprofitable. In explaining the result, my Kool-Aid drinking trader even accepted partial responsibility for at times misinterpreting the very information he was analyzing. It was along the lines of that he ought to have recognized the type of pattern that was evolving but stupidly interpreted the wrong shape. It was almost as if the results were not the result of the faulty religion but of the less than completely faithful practice of one of its adherents. So what use to a profit-oriented trading room is a fully committed chartist who can't be trusted even to follow the charts? At this stage I must confess that we had found ourselves in this position as a last-ditch effort on my part to salvage some profitability out of a trader I'd hired who had to this point been consistently losing money. His own market views expressed in the form of trading positions had been singularly unprofitable, so all that remained was to see how he did with somebody else's views. The experiment wasn't just intended to provide a “live ammunition” record of our in-house technician's market insights, it was my last best effort to prove that my recent hiring decision hadn't been a bad one. Sadly, his failure confirmed my earlier one and I had to fire him. All was not lost though, because he was able to transfer his unsuccessful experience as a proprietary trader into a new business advising clients on their hedge fund investments.
