Apple will give a forecast for this current quarter that may shock investors, according to a BTIG analyst Walter Piecyk.

“Smartphone upgrade rates remain at record low levels and do not appear poised to rebound in the first calendar quarter,” stated the analyst in a Friday note entitled “How bad will Apple’s guidance be?”

Piecyk estimates revenue guidance for the March quarter could be just $60 billion, 12 percent below a Wall Street consensus of $68 billion, according to the note.

The analyst got to his lower forecast after looking at lower-than-expected smartphone upgrade rates from Verizon, as well as weak iPhone X sales. Currently, the Street is expecting Apple to sell 61 million iPhones in the second quarter, but Piecyk believes it will be closer to be 53 million.

“Concerns about iPhone X sales have been well documented. Apple’s stock has shrugged off a slew of analyst and press reports that highlight these trends,” Piecyk added. “The incremental
concern is whether Apple can hit or even come close to consensus revenue estimates in future quarters, due to its reliance on average sale price growth.”

Apple is one of the market’s best-performing large-cap stocks of the past year, rallying 40 percent over the past 12 months through Thursday versus the S&P 500’s 24 percent gain. But they have struggled lately, down 4 percent this week.

Piecyk’s comments echo those made by other top tech analysts. Wells Fargo Securities reiterated its market perform rating on Tim Cook’s company last month, saying the latest China export data hint that iPhone sales may disappoint in the December quarter as well.

Apple is set to report earnings next Thursday.
