What happened

Shares of LyondellBasell (LYB -0.56%) slumped 17.6% in January, according to data from S&P Global Market Intelligence. The stock trended downward due to weakness in the oil market and then saw sell-offs following the publication of the company's fourth-quarter report at the end of the month.

So what

Sliding oil prices put pressure on LyondellBasell stock throughout January, and concerns about the economic impact of the 2019-nCoV coronavirus dimmed the outlook for the company's refining segment. Crude oil prices declined 15% in January, marking the biggest drop in the month since 1991, according to a report published by Julianne Geiger at Oilprice.com. Combined with the fourth-quarter earnings miss at the end of the month, the bearish oil market created conditions that pushed LyondellBasell stock down double digits.

Now what

LyondellBasell stock has regained some ground February, with shares up roughly 5% in the month's trading so far.

The company expects that 2020 results for its olefins and polyolefins Americas segment will benefit from additional capacity from the business' Hyperzone polyethylene plant. Management also expects to make substantial progress on the construction of its propylene oxide and tertiary butyl alcohol plant, which it expects will be completed in 2021 and help drive growth for its intermediates and derivatives segment.
