The stock is still 14% below its all-time high of $134.54 set back in February. It’s been haunted ever since by the so-called tough compare: The belief that Apple’s December quarter last year—the most profitable in the history of capitalism—set a bar so high the company would be hard-pressed to beat it this year. And for investors, a stock like Apple—perceived as a high-flyer—has to keep climbing or it falls back to earth.

But we’re getting ahead ourselves. Today’s results are for fiscal Q4, which should set another September quarter record for Apple and round out a record fiscal year. Fortune‘s panel of analysts—a mix of Wall Street professionals and veteran amateurs—is calling for earnings of $1.92 on sales of $51.38 billion, slightly higher than the Street ($1.88 on $51.12 billion).

Whether Apple beats last September’s numbers may matter less than the forward-looking guidance it gives for December. If it guides much lower than the Street’s estimates (earnings of $3.22 on sales of $77.14 billion) there could be hell to pay.

I’ll be monitoring the earnings results, and you can too. Apple’s conference call with analysts today will be webcast live starting at 5 p.m. ET (2 p.m. PT). Click here to listen in.

Tomorrow I’ll post Fortune’s quarterly ranking of the best and worst Apple analysts. Stay tuned.
