Waters shares closed down nearly 13 percent for the trading week ended Tuesday after the company lowered its earnings projections for the third quarter, citing "slower than expected" sales growth. The company, which originally anticipated 8 percent year-over-year growth for the third quarter, said last Friday that it now expects only 3 percent year-over-year growth for the period (see story this issue). The company's shares fell 11.6 percent that day and never recovered.
