Should I Buy Costco Stock Before Earnings?

Judging by the company's performance for the past several years, Costco Wholesale (NASDAQ: COST) may look like a no-brainer stock to buy right now. When you factor in recent record Black Friday sales and a potential upcoming increase in the cost of a membership for the warehouse club retailer, it's not hard to understand why Costco stock is popular among long-term investors. The only real question for these investors is whether now is the right time to buy Costco stock.
