Stock futures are pointing to steep losses for the broader market as investors return from a long weekend following one of the market's best weekly performances in several years. Although the market has recaptured almost 80% of what it lost in its correction two weeks ago, several brokerage firms weighed in over the weekend that the last correction could be the first of several this year. None of the firms were outright bearish on equities, but rather displayed a cautionary tone. The domestic economic calendar is quiet today while post-earnings weakness in Walmart (WMT) shares is providing a headwind to the Dow. In early pre-market trading, Dow futures are 157 points below fair value, Nasdaq futures are 38 points below fair value and S&P futures are 15 points below fair value.
