Nowadays, it seems as though the market is always teetering on the knife’s edge. Depending upon which way the wind is blowing on any given day, or what chatter is coming across the newswires, markets around the globe are moving at lightning fast speed. Sentiment can change instantly, with the release of unexpected economic data, market movements, or surprising actions of central bankers. The effect of high frequency trading (HFT) has turned the decades old profession of investing into a high stakes gambling operation, and more characteristic of commodity trading. Such erratic behavior on a daily basis makes it difficult, if not impossible, for analysts to formulate a long-term view, and for investors to maintain a long-term, “Buy and hold” position. “As soon as you think you’ve got the key to the stock market, they change the lock,” said long-time market guru, Joe Granville.
