Here's a brief overview of what to look for when each company reports results.

All eyes on strategic imperatives

International Business Machines is the first of these two companies scheduled to report quarterly results. IBM will report results after market close this Thursday and will host a conference call to discuss results at 5:00 PM ET. 

IBM investors have recently turned their focus toward IBM's more nascent strategic imperatives, or the company's cloud, analytics, mobility, and security offerings. Growing to 40% of total revenue one year earlier than the company was targeting, IBM's strategic imperatives are growing faster than the rest of its business. While total third-quarter revenue was flat year over year, strategic imperatives revenue was up a nice 16%.

For investors to remain optimistic about IBM's strategic imperatives, look for this segment's growth to match or exceed the 16% growth achieved in Q4.

On average, analysts expect IBM to report total fourth-quarter revenue and EPS of $21.7 billion and $4.89, respectively. In IBM's fourth quarter of 2015 the company reported revenue and EPS of $22.1 billion and $4.84, respectively.

Can steep revenue growth persist?

For Alphabet, which reports its fourth-quarter results exactly one week after IBM, revenue growth will be key. Alphabet's core Google advertising business has been firing on all cylinders, helping total revenue and EPS exceed expectations in the company's most recent quarter. The company reported 20% and 23% year-over-year growth in revenue and EPS in Q3, respectively, as aggregate paid clicks, or the total number of clicks advertisers pay Google for, soared 9% sequentially and 33% year over year.

While Alphabet CFO Ruth Porat has warned that tougher year-over-year comparisons will make similar growth in Q4 unlikely, analysts are still modeling for a sharp hike in the company's top line. On average, analysts expect Alphabet's revenue to increase 18% year over year. Can the company's ad revenue continue strongly enough to help the company achieve such a strong increase in total revenue, even when the company is up against a tough year-ago comparison?

The consensus analyst estimate for Alphabet's fourth-quarter revenue and non-GAAP EPS is $25.1 billion and $9.66, respectively. These estimates imply 18% and 11% year-over-year growth in revenue and non-GAAP EPS, respectively.

After Alphabet reports its fourth-quarter results on Thursday, Jan. 26, the company will host a live conference call to discuss the results at 4:30 PM ET.
