Jumei’s stock finally takes off while Tilly’s shares come crashing down during aftermarket trading. Palo Alto beat analysts’ estimates but Costco missed, and Abercrombie is set to report earnings today US markets opened slightly lower yesterday, and continued to trade sideways for most of the session. All three major indices ended the day negligibly lower. The S&P 500 Index (SPX) remained above the 1,900-point level, the Dow Jones went down a quarter of a percent, and the tech-heavy Nasdaq fell 0.28%. Most investors and traders will be looking at the macro picture today, with some key data coming out of the US before markets open as well as during the trading session. The Department of Labor and the Bureau of Economic Analysis will release initial jobless claims as well as a second reading of the first-quarter GDP. This could set the tone for where the session ends today.
