Costco Wholesale Corporation (COST) Is a Victim of Its Own Success

After reporting consistent earnings and same-store sales beats throughout 2018 that have sent its stock up more than 30 percent on the year to new all-time highs, Costco Wholesale Corporation (NYSE: COST) may finally be becoming a victim of its own success. Wells Fargo analyst Edward Kelly downgraded COST stock from “outperform” to “market perform” and says it will be difficult for Costco to impress the market at this point. Kelly says Costco’s performance has been stellar in recent quarters, but it’s unlikely the company will continue to deliver its impressive sales growth in 2019.
