Shares of Littelfuse (NASDAQ: LFUS), LyondellBasell (NYSE: LYB), and MKS Instruments (NASDAQ: MKSI) rose 13.6%, 15.6%, and 17.9%, respectively, in September, according to data provided by S&P Global Market Intelligence. All three handily outperformed the S&P 500, which only rose 1.72% for the month.
Although shares of controls and instruments manufacturer MKS are now way up for the year -- 40.9% so far in 2019 -- the other stocks have lagged. Electrical components manufacturer Littelfuse's shares have only risen 2.6% for the year, while shares of chemical maker LyondellBasell are only up 0.9%, badly trailing the market.
These three stocks' outperformance was a result of trade war news, but it may be too early to cheer. Image source: Getty Images.
