The recent correction on Wall Street was largely driven by concerns that inflation could be returning to the economy, possibly pushing the Federal Reserve to become more aggressive in raising interest rates. But while that was the catalyst, it wasn’t the sole reason why stocks declined as rapidly as they did. A number of factors unrelated to economic fundamentals are seen as having contributed to the recent weakness, which pushed the Dow Jones Industrial Average DJIA, -0.67% and the S&P 500 index SPX, -0.55% in to correction territory for the first time in about two years. Issues related to technical analysis have been cited, with traders noting how losses in the S&P accelerated after it broke through its 50-day moving average, a closely watched level for short-term momentum, while others have pointed to the unwinding of strategies that require managers to sell risk at a time when volatility rises. Still others have cited program trading, or computer-driven moves, although the impact of that is difficult to quantify.via
