 Shares of Autoliv Inc. sank 6.8 toward a four-month low in premarket trading Friday, after the Sweden-based maker of automotive safety systems reported second-quarter profit and sales that missed expectations and cut its full-year outlook, citing the continued impact of the COVID-19 pandemic, the negative effect of the semiconductor shortage and continued rise in raw material prices. The company swung to net income of 104 million, or 1.19 a share, from a loss of 175 million, or 2.00 a share, in the year ago period.
