After dropping more than 200 points on Monday, the Dow Jones Industrial Average was rising slightly on Tuesday

Several U.S. corporate giants are set to report earnings Wednesday. Here's a look ahead at what to expect out of these eight heavy hitters:

Anthem

Anthem Inc. (ANTM - Get Report) is set to report fourth quarter earnings Wednesday January 30 before the opening bell. Analysts are expecting adjusted earnings-per-share of $2.19, representing a 70% year-over-year increase, as expected GAAP EPS of $1.98 would be a 58% decline. Revenue is expected to be $23.32 billion. 

AT&T

AT&T Inc. (T - Get Report) reports fourth quarter earnings before the market opens Wednesday. The telecom giant is expected to post adjusted EPS of 86 cents and GAAP EPS of 57 cents. Revenue is expected to be $48.5 billion. 

Boeing

Boeing Co. (BA - Get Report) will report fourth quarter earnings before the market opens Wednesday. Wall Street is looking for adjusted EPS of $4.59 on revenue of $26.93 billion. 

Tesla

Tesla Inc. (TSLA - Get Report) will report fourth quarter earnings after the market closes Wednesday. After Tesla investors enjoyed the first quarterly profit in two years in October, they'll look for another profit, even after CEO Elon Musk said that profit can only be attained "with great difficulty, effort and some luck." Analysts are estimating adjusted EPS of $2.15 and GAAP EPS of $1.05. Revenue is expected to grow 115% year-over-year to $7.07 billion. 

McDonalds

McDonald's Corp. (MCD - Get Report) reports fourth quarter earnings Wednesday before the opening bell. Analysts are looking for adjusted EPS of $1.89 on revenue of $5.17 billion. 

Facebook

Facebook Inc. (FB - Get Report) will report fourth quarter earnings after the market closes on Wednesday. Adjusted EPS is expected to be $2.49. Revenue is expected to be $16.39 billion. With the stock still 34% off of its all-time high, many analysts are saying there's a buying opportunity, as Instagram, its next growth driver, looks positioned to continue its explosive growth in both users and monetization.

It's been almost one year now that Facebook shares have been hammered over concerns regarding data and privacy security, which has caused enormous headline risk to the stock. "The headlines may be negative but so long as the platform provides best-in-class ROI [return on investment], ad buyers will continue to give them money," said Zev Fima, research analyst for Jim Cramer's Action Alerts Plus Portfolio, which owns Facebook. 

Microsoft

Microsoft Corp. (MSFT - Get Report) will report second quarter for its fiscal year 2019 earnings after the closing bell Wednesday. Analysts are expecting adjusted EPS of $1.09 on revenue of $32.5 billion. 

Alibaba

Alibaba Group Holding LTD BABA will report third quarter for its fiscal year 2019 earnings before the market opens Wednesday. Adjusted EPS is expected to be $11.39, with GAAP EPS expected to be $7.83. Revenue is expected to come in at $119.36 billion.
