Walmart (WMT) marked the unofficial end to earnings season this morning by reporting slightly better than expected earnings on inline revenues. The company also lowered guidance for Q1 and the full year. As a result of the lowered guidance, the stock is getting pummeled in the pre-market and is on pace to gap down close to 9%. For many high-growth stocks, a 9% gap down in reaction to earnings may not sound extreme, but WMT has historically been a much less volatile stock. Since 2001, its average one-day move in reaction to earnings has been 2.9%, so if current levels hold through the end of the trading day, today’s move would be more than triple its historical average move.

The table below shows prior earnings reports since 2001 when WMT gapped down by at least 5%. It’s only happened five other times, and it has never gapped down more than 8%, so that would put today’s downside gap on pace to be the most negative gap opening in reaction to earnings since at least 2001. As Sam Walton’s quote above says, high expectations are the key to everything, and when a stock like WMT heads into an earnings report trading for over 37 times earnings and lowers guidance, reactions like this aren’t surprising.

For the broader market this morning, S&P 500 futures indicate a decline of about 0.3% at the open and trade near their lows of the day. Today’s weakness, however, comes just hours after the S&P 500 closed at an all-time high yesterday – its third record closing high of the year. The market doesn’t look like it’s done much since its high in December, but YTD, the S&P 500 has managed a rally of over 4%. We’ve seen some weak housing-related data this week, but today’s economic focus will shift to jobless claims and the Philly Fed at 8:30 and leading indicators at 10 AM. Also on the calendar, we’ll hear from various Fed officials throughout the day, starting with Chicago Fed President Goolsbee just after the opening bell.
