Aug 21 (Reuters) - U.S. stock index futures rose on Wednesday as upbeat earnings reports from retailers Lowe's and Target reflected robust consumer demand, helping ease some concerns around slowing economic growth.
Shares of home improvement chain Lowe's Cos Inc rose 10.5% in premarket trading as it joined bigger rival Home Depot in beating profit estimates.
Big-box retailer Target Corp surged 13.4% after it beat quarterly same-store sales and profit estimates.
