It seems you over looked something about the company. There's a very good reason not to buy Monster Mart's shares. Retail company start-ups usually take years before their shares show a significant price rise. The Super Bowl is actually a bigger event than Monster Mart grand openings. Monster Mart's negative cash flow is a sign of trouble.
Margins are irrelevant in the retail industry.
The answer is number 3. Cash flow is measure that tells an investor that a company is actually bringing cash in to the company's coffers. A company with negative cash flow may be in deep doo-doo. In order for such a company to expand, they often have to either issue more stock or take on greater debt. Issuing stock lessens the value of the shares that a person owns, and taking on debt actually ties up even more of a company's precious cash.
