A combination of factors pushed U.S. (and global) stocks sharply higher during the second half of the week. One big factor was the Wednesday Fed statement that it would be “patient” in raising rates next year. Another was a bounce in a very oversold oil market late in the week which gave a big boost to energy shares (which make up 8% of the S&P 500). Energy shares rose 9.5% and were by far the week’s strongest sector. Material stocks (led by copper and aluminum) came in second with a weekly gain of nearly 5%. All other sectors gained on the week as well.
