Everyone wants to build out the "perfect" retirement portfolio. Three years ago, the Motley Fool's Brian Stoffel took $40,000 of his own retirement money and split it evenly among 10 companies that he publicly called out as being investment-worthy.

Since then, his picks have accumulated a 52% return -- for a total of almost $61,000. But today, he's focusing on the second-best-performing of those 10 stocks--Latin America warehouser PriceSmart (NASDAQ:PSMT).

Although Brian has no intention of selling his shares, he does think that PriceSmart bears have legitimate concerns about the stock. Watch below to see exactly what those concerns are, and why -- despite these concerns -- Brian plans on holding his shares.
