Wall Street ended an ugly week further to the downside but off the lows of the day. The strengthening dollar, dipping oil prices and mixed economic reports pushed the Dow to drop triple digits. Crude oil lost $2.21 a barrel to settle at $44.84. It was a broad sell-off with IBM (IBM) and United Technologies (UTX) leading the blue chips lower. Harley Davidson (HOG) slid after Deutsche Bank (DB) cut its price target for the stock on its foreign exchange exposure. Separately, the motorcycle maker said its laying off 169 employees. Apple (AAPL) started the week unveiling of its watch on Monday but finished with a third straight week of declines. But there were bright spots in the session including El Pollo Loco (LOCO). The restaurant chain gained 13% after beating Wall Street's earnings expectations.
