Shares of Costco are nearly unchanged on Thursday despite the quarterly results that missed Wall Street forecasts. Profit came in at $1.07 a share, $0.03 short of expectations, but earnings were up 3% from the same period last year. Sales were up 7% year over year to roughly $26 billion, a bit more than what analysts projected. Sales at stores opened for at least one year were up 6%, not bad considering the harsh winter most the country experienced. Meanwhile, sales at international stores grew 8%. A handful of Costco's competitors saw their revenues decline.
