RadioShack, the struggling electronics retailer, on Tuesday said it might close 1,100 stores — about a fifth of all its outlets — after it reported its eighth straight quarterly loss. The Forth Worth company said it had a net loss of $191.4 million for the fourth quarter — more than triple what it lost a year earlier. Its fourth-quarter revenue slumped 20% to $935.4 million. Like many bricks-and-mortar retailers, RadioShack is struggling to reverse declining foot traffic to its stores and fend off competition from other retailers, including Amazon.com.
