Whole Foods Market (WFMI) is one of those rare stocks in the after-hours that finds a direction post-earnings and keeps going that same way in the following day's regular session. More than 80% of the time it posts an earnings-driven after-hours downside move, it heads deeper in the red the next day. When it gains in the off-hours, more than 70% of the time it finds more robust upside momentum the following day. So, if traders are long or short tonight they can reap big returns come Thursday.
WFMI is scheduled to report Q1 results after the bell tonight (Wednesday, Feb. 9), and analysts polled by Thomson Reuters are expecting a profit of $0.46 per share on revenue of $2.98 billion.
WFMI has developed a steady pattern of widening price moves between the sessions following its after-hours earnings-related events, extending its move after 20 of its past 26 earnings-related events.
