FORTUNE — One thing that jumps out at you when you’re looking at a lot of Apple (AAPL) analysts’ estimates — as I have been for the past couple of weeks — are those large, last-minute adjustments.
Sell-side analysts will often offer their clients one set of estimates a few weeks into the quarter and a second shortly before the results are due. When the change is more than billion dollars — up or down — it’s a pretty strong signal one way or the other.
Two of those billion dollar-plus signals came in last week, just a few days before Apple was scheduled to report its earnings for the fiscal first quarter of 2014.
- Goldman Sachs’ Bill Shope upped his revenue estimate by $1.26 billion (2.2%)
- Credit Suisse’s Kulbinder Garcha raised his $2.73 billion (4.8%).
Both analysts attributed their new, more bullish attitude to what they’re picking up about iPhone and iPad sales over the holiday quarter. As Shope put it:
Coming soon: The full spreadsheet of Q1 2014 estimates. We’ll get the actual results Monday after the markets close.
