As parts of the U.S. prepare for a "snowbomb" this week, Walmart investors should be preparing for a first quarter "bomb" when Walmart reports earnings. Belus Capital Advisors' Brian Sozzi thinks Walmart's first quarter could wreak havoc on a dividend paying-only stock portfolio. In particular, Sozzi is worried about Walmart's new price-comparison program, called "Savings Catcher," and a Black Friday-like spring sale for home improvement goods aimed to win business from Home Depot and Lowes.

At the time of publication, Sozzi was long XXX, although positions may change at any time.

At the time of publication, Sozzi held no position in the stocks mentioned.

Brian Sozzi is the CEO and Chief Equities Strategist of Belus Capital Advisors. He is responsible for developing and managing an equities portfolio of mid- and large-cap positions, in addition to leading the firm's digital content initiatives. He is also a personal finance columnist for Men's Health magazine.
