A little bad news goes a long way.
Wednesday's news from mattress company Tempur-Pedic International Inc. that it was cutting its full-year profit and revenue forcasts caused the Kentucky-based company's shares to plunge 47 percent in mid-morning trading.
CEO Mark Sarvary said in a statement sales so far this year have been "disappointing and below plan, primarily due to changes in the competitive environment."
The dire news from a rival caused shares of Plymouth-based Select Comfort Corp. to decline about 19 percent.
The overall financial picture for Select Comfort appears different from that of Tempur-Pedic's, however. In April, the Select Comfort posted its 13th consecutive quarterly profit. Last month, Chief Operating Officer Shelly Ibach, a veteran of Target Corp., Marshall Field's and Macy's, took over as CEO.
Another competitor's shares plunged, as well. Mattress Firm Holding Corp.'s stock is down 22 percent in morning training.
