Wall Street lost its grip on new highs established during the previous trading session on Friday, as the major US indices and exchanges stumbled to close out the week on a particularly low note. The rather vicious sell-off took a moment to ramp up as investors initially seemed pleased with good numbers from the Labor Department’s non-farm payrolls report that left the current 6.7 percent unemployment rate unchanged. Growth stocks in the tech and biotech spaces were largely responsible for the undertow that pulled markets lower to close out the week’s trading, however, as the NASDAQ took the hardest hit of the day, off more than 2.5 percent by the bell.
