This brings their year-to-date 2017 returns to a torrid nearly 86% and 45%, respectively. For context, the S&P 500 has returned 12.7% so far this year.
We can probably attribute the rise in the stock prices of SQM and Albemarle to reports that a Chinese government official said over the weekend that China had started looking at banning the production of petroleum-fueled cars. Such a ban would give a boost to electric vehicles -- and lithium is an essential component in the lithium-ion batteries used in EVs. Reports didn't indicate a timeline for such a ban.
This news out of China is no doubt the biggest driving force behind Monday's movements in SQM and Albemarle. However, SQM stock may also still be getting a lift from Reuters' report in July that Chinese private-equity firm GSR Capital is looking at buying a substantial stake in the Chilean lithium producer.
If this ban comes to fruition -- and my guess is that it will -- it will be great news for the electric-vehicle space, which includes EV makers, lithium producers such as SQM and Albemarle, and others. China is the world's largest auto market, so a ban on producing gasoline and diesel-fueled cars could give the already powerful electric vehicle movement a huge charge.
