Youth fashion chain Aeropostale Inc on Wednesday said its October same-store sales climbed 11.7 per cent as it promoted more and benefit from higher store traffic.

The New York-based operator of 365 stores, which cut its profit outlook recently, said net sales in the four week period ended November 2 rose 43.2 per cent to $48.7 million from $34m in 2001.

It added third quarter sales soared 34.3 per cent to $169.2m from $126m and same-store sales grew five per cent. It now expects earnings for the quarter of 37-39 cents a share.

Aeropostale chairman and CEO Julian Geiger said: "We recorded a better-than-expected comparable store sales performance during the month of October.

"We quickly responded to changing market conditions with additional promotions and capitalised on a rebound in traffic levels and customer activity from their low point in mid to late September.

"As a result, not only were we able to generate solid comp store gains and clear inventory, but we were able to record a slightly improved level of gross margins than we had expected."
