US stocks rose, with the Standard & Poor’s 500 Index turning positive for 2016 in the wake of a dovish Federal Reserve that helped the gauge post its longest weekly winning streak since November. The equity benchmark joined the Dow Jones industrial average to advance for the year, staging one of the biggest turnarounds in history. “It’s been a good week and a great month for equities as stocks have benefited from the winds of change,’’ said Terry Sandven, who helps oversee $126 billion as chief equity strategist at US Bank Wealth Management in Minneapolis. “Many of the items that have plagued sentiment and overall equity returns, really since the beginning of the year, seem to be of less of an immediate concern.’’ Energy and raw materials have led the S&P 500 over the last five weeks with gains of more than 16 percent. Energy companies posted the longest streak of weekly advances in 10 months, while raw-materials producers capped the best such stretch since November 2014. A tumble in the dollar Thursday brought on by a more dovish Fed helped push the two groups to three-month highs yesterday. The Fed’s tempered outlook for rate increases knocked down traders’ expectations as reflected in futures prices, according to data compiled by Bloomberg.
