Among stocks that closed lower, Intel ( INTC 2.20% ) dropped 1.5%, despite news that it has finally started to see launches of smartphones using its low-cost mobile chips. Phones using Intel's Lexington chips came out in Kenya and Thailand, showing the importance of having low-end products with inexpensive components in order to meet demand in less prosperous emerging markets. Clearly, Intel needs to get developed-market penetration in order to boost profits meaningfully, but the releases are still a good sign that the company is making progress. Elsewhere, Liquidity Services ( LQDT -0.79% ) lost more than 22%, after revising its range for full-year fiscal 2013 earnings guidance downward by $0.15, to $0.21 per share. Although the auction-portal company beat estimates after excluding one-time items, the negative forward guidance is just the latest evidence that companies are uncertain about whether the economic recovery of the past several years can keep pace, let alone pick up steam.
