The fact that this happened in August may have something to do with its relative unimportance. In the final doldrums of summer, trading volume is historically very low, and today wasn't an exception. Had this occurred in the beginning of the year, or sometime in the fall, we may have seen a more characteristic market freak-out.But let's say, for the sake of optimism, that the market's muted reaction to a major exchange shutdown is evidence of a maturing, if jaded, participant base. Getting wiser Over the past few years, many investors' faith in the market has been repeatedly shattered, whether by corporate wrongdoing, macroeconomic meltdowns, or "technical errors" stemming from the exchanges themselves. We've seen nearly every conceivable excuse to sell off triple-digit percentages in the markets. Is it unreasonable to posit that the market may be wising up a bit to the unpredictable nature of the business? The NASDAQ OMX Group, Inc. (NASDAQ:NDAQ) shutdown was certainly inconvenient, it hurt brokerage firms that rely on execution fees, and it should raise eyebrows and some questions as to the health of our trading systems. But should it damage the values of public companies? In a logical world, that answer is a definite "no." The fact that the market sided with logic is incredibly refreshing. A long way to go The Yahoo! Inc. (NASDAQ:YHOO) piece cites a managing director from LandBolt Capital who believes that the impact will be felt in the coming days. At the time of this writing, it's impossible to know, but it's hard to imagine the market woke up this particular Thursday feeling older, more mature, and ready to smoothly handle incidents. As an investor, and one whose worries may have been renewed by yesterday's glitch -- the umpteenth in a just a few years -- remind yourself that you invested in companies, not a stock market. Your fractional ownership of Apple Inc. (NASDAQ:AAPL) was not affected, in the long run, by some error on Wall Street. The glitch didn't carry over to Foxconn and zap underpaid laborers out of existence for three hours. That may sound silly, but it's exactly what is implied when the market dives 300 points on the back of a technical error.
