Getty Images Even as Dow closes at record, investors are mindful on how a further fall in tech shares could crush broader gains.As tech shares continue to sell off, investors are focusing more on how that market-leading sector will dictate the direction of the broader benchmarks in the coming week as the Federal Reserve has signaled a commitment to tightening and economic data remain lackluster. On Friday, the Dow Jones Industrial Average DJIA, +0.11% closed at a record, notching weekly gains for a fourth straight week, while the S&P 500 indexSPX, +0.03% finished fractionally higher, and the Nasdaq Composite IndexCOMP, -0.22% sank 0.9% for the week. Tech stocks will remain a focus as their recent selloff has shown few signs of reversing following the Federal Reserve’s rate hike and expectations of another one in September coupled with a paring of the Fed’s $4.5 trillion balance sheet, said Bob Pavlik, chief investment strategist at Boston Private Wealth. How oil prices CLN7, -0.40% test a $44 a barrel floor will also be a focus for the week, he said.via
