Since April of this year, shares of Walmart (#WMT) have barely been hovering over $140. There's a battle between bulls and bears as they play tug-of-war and bears are now slowly dragging the price below $140.

Now that shares are at $139.08, investors may want to buy on the stock and give it support. But do the fundamentals stack up to warrant a buy?

Last month, #Walmart reported Q1 earnings that beat analyst expectations. Earnings came in with non-GAAP EPS of $1.69 (beats by $0.48) and revenue of $138.3B (+2.7% Y/Y).

But can revenues keep going up? Numbers were largely driven by an increase in membership sales and eCommerce. If investors believe that at least one of those can continue to rise, then a support buy below $140 may be warranted.
