Tim Cook hasn’t done Wall Street any favors by holding quarterly Apple Watch sales numbers so close to his chest. Apple’s CEO has explained several times that he’s not announcing them in order to keep his competitors in the dark. But as a result he’s also kept Apple analysts in the dark, and the effect is apparent in the spreadsheet below. Left to their own devices, the 26 analysts I’ve heard from so far—16 Wall Street professionals (in blue) and 10 independents (in green)—have submitted estimates for last quarter’s sales with a range greater than I’ve ever seen for an Apple AAPL 5.29% product: from a low of 3.1 million to a high 10.5 million.
