The Nasdaq had announced this morning that they are rebalancing the Nasdaq 100 Index to lower the influence of Apple Inc. (NASDAQ:AAPL) on behalf of companies like Google, Cisco, Microsoft, and Oracle. The Nasdaq said that the goal was to make the weight of the Index Securities closer to the actual market capitalizations of the companies involved in the 100 Index. The weight of Apple in the index is over 20%. In the past two years, Apple’s share have been up over fourfold. The rebalancing will take place on May 2nd and Apple will only make up 12% of the Nasdaq-100. [GeekWire]

In September 2008, Google stock appeared to be trading at $0.01 temporarily when it should have been over $400.  The glitch had to be investigated by Nasdaq Stock Market operators and it resulted from erroneous orders that were routed from another exchange.  This time it looks like a similar case is happening with Intel Corporation (NASDAQ:INTC) and Oracle Corporation (NASDAQ:ORCL).

In the after hours stock price, Intel is reporting a $7.91 per share which is -49.52% from the closing price. Oracle is showing an after hours stock price of $9.63 per share which is -49.77% of the closing price. When this happened with Google last time any trades that took place at the $0.01 price were automatically canceled was not allowed to be appealed. As exchanges are becoming all-electronic they are susceptible to problems.
