Technical analysis involves moving averages, retracement levels, well-defined zones of historical support/resistance ... in other words, lines in the proverbial sand that often help make sense of the various market machinations. It's after 4:00 and we've all been saved by the bell, if a little worse for wear. But heck, a 9% drop like the Shanghai Composite endured would have taken the Dow Industrials (INDU) south of the 11,500 mark. As Sarah pointed out moments ago, the Dow's drop on this late-winter Tuesday will likely end up being no big deal.
That said, let's take a quick look at some technical trickery. The NASDAQ Composite (COMP) gave back nearly 97 points today and closed below its 10-week and 20-week moving averages. These trendlines had worked in tandem to support the tech-rich index since mid-August. The S&P 500 Index (SPX) violated its respective 10-week and 20-week trendlines as well, and closed below the 1,400 mark for the first time since December 1. The S&P 100 Index ended the day at its worst level since early November and broke free of a stifling trading range that had been in place since the start of 2007. And the Dow also breached its 10-week and 20-week trendlines, testing the 12,200 mark for the first time in nearly three months.
