The NASDAQ (National Association of Securities Dealers Automated Quotations) stock market is an American stock exchange. Many have nicknamed it ‘Nascrack” or “nascrack” (NASDAQ + crack cocaine) because of the market’s volatility. “For example, many stocks two years ago that were on the BIG board or the NAScrack are now on OB due to them falling out of meeting the requirements to be on said board” was cited in print in 2002.
   
“Above is the NASCRACK Index so named for it’s wild and crazy actions” was cited in print in 2010.

OB = “out of business”.  While not true, it’s often not far from the truth. For example, many stocks two years ago that were on the BIG board or the NAScrack are now on OB due to them falling out of meeting the requirements to be on said board.

The NasCrack is trading down because of the new laws requiring them to expense options. Companies in the Naz have been “bumping” and “running” their shareholders.
