1221 ET - Fewer people are picking up DIY projects for their cars, and this is weighing on Advance Auto Parts' earnings. Same-store sales fell 0.5% in the quarter, where analysts expected a rise of 1.4%, and was mostly due to declining do-it-yourself and retail demand. Net sales edged down to $2 billion from $2.01 billion, missing expectations of growth to $2.04 billion. "In the DIY channel, sales declined more than we anticipated, particularly during the last four weeks, as tighter household budgets weighed on consumer spending," CEO Shane O'Kelly says in an earnings call. Shares are down 26% to $41.70.
