It's certainly possible that Costco could hit $1,000. Just how long it will take to do so is a harder question to answer, though. There are too many variables at play, notably including the health of the overall economy.The most likely reason Costco's share price might not reach $1,000 is the potential for a stock split. As mentioned, the company has conducted several stock splits over its history. Costco's management team could decide another stock split is in order well before the share price hits $1,000.
