What happened

Shares of Target (NYSE:TGT) jumped on Tuesday following the retailer's fourth-quarter report.

The stock was up about 5% at 3:30 p.m. EST.

So what

Target reported fourth-quarter revenue of $22.7 billion, flat year over year and $70 million above the average analyst estimate. The fourth quarter of 2017 had an extra week, which reduced the revenue growth rate.

Comparable sales surged 5.3%, with stores contributing 2.9% of that growth and digital sales contributing 2.4% of that growth. Digital sales grew by 31% year over year, and they accounted for more than 10% of Target's total revenue.

Non-GAAP earnings per share came in at $1.53, up from $1.36 in the prior-year period and $0.01 better than analysts were expecting. The company expects to produce non-GAAP EPS between $5.75 and $6.05 in 2019, higher than the average analyst estimate of $5.61.

Now what

Target's strategy of rolling out exclusive brands, investing in online initiatives like free two-day shipping and curbside pickup, and lowering prices is paying off. The retailer is proving that it can effectively compete against Walmart and Amazon.

Target won't get the same year-over-year earnings benefit this year from a lower tax rate, but low- to mid-single-digit comparable sales growth and continued share buybacks will help the company hit its earnings guidance.
