Market sell-off is 'more of an interruption' than trend change: Strategist

CNBC's Kelly Evans discusses the market sell-off with Neil Hennessy, chief investment officer at Hennessy Funds, and Sameer Samana, senior global market strategist at Wells Fargo Investment Institute. Stocks fell sharply on Thursday as investors paused in the wake of a recent rally to all-time highs. Tech, the market leader since the rebound began in late March, was the the day's biggest laggard.
