March's US retail sales figures were through the roof, but one analyst thinks the current growth rate can't be sustained for long. MarketWatch is reporting on a note to investors from Goldman Sachs analyst Robert Higginbotham, who recently downgraded his assessment of stock in retailer GameStop to a "sell" rating.

According to Higginbotham, GameStop shares are "poised for a pullback as industry growth remains on a path toward deceleration from its current peak," suggesting not that the industry itself has peaked, just that growth figures later in the year likely won't be quite as impressive as March's 57 percent spike.
