Tesla Motors (TSLA) - Get Report and Nvidia (NVDA) - Get Report took a steep hit Thursday, following earnings results and an analyst downgrade, respectively. A Chinese web services company also took a slight hit during the regular trading session, but managed to rebound in after-hours trading after reporting its fourth-quarter results.

Tesla Motors took a hit, following its fourth-quarter earnings results that posted a wider than expected loss and an announcement that its chief financial officer would be stepping down to take an unnamed public policy position.

The high-end electric carmaker's shares tanked after posting a fourth quarter net loss of 69 cents a share on revenue of $2.28 billion. Although the revenue beat analysts' expectations of $2.19 billion for the quarter, Tesla's net loss surpassed the 43 cents that Wall Street was expecting, according to Thomson Reuters.

Tesla apparently wasn't able to sway investors to look favorably on its stock, even after it reiterated its impressive production schedule plans for its mass-market Model 3 sedan. Tesla expects to deliver a whopping 5,000 Model 3 vehicles per week in the third quarter and ramp it up further to 10,000 per week in the fourth quarter.

However, Wall Street still remains skeptical that Tesla can pull off such a bold production schedule, once it begins to pump out its latest vehicle.

Meanwhile, Tesla also announced its CFO Jason Wheeler will soon be stepping down to assume a public policy role. Former CFO Deepak Ahuja, who stepped down in 2015 to make way for Wheeler, will replace him.

Tesla shares fell 6.4% to end the day at $255.99 a share.

Nvidia plummeted after BMO Capital markets downgraded the chipmaker to underperform from market perform. The analyst cited that Nvidia's valuation was less attractive, given it is facing increasing competition. BMO lowered the company's price target to $85 from $100.

Nomura Instinet also weighed in and cut the graphic chipmaker's price target to $90 from $100 and lowered its rating to reduce from buy, according to an Investor's Business Dailyreport.

The company's stock has been on a rocket ride in the past year, soaring 220%, and investors would be wise to let analysts knock it down further before jumping in, said TheStreet's Jim Cramer, co-manager of the Action Alerts PLUS portfolio, on CNBC's "Stop Trading" segment.

Nvidia plunged 10.3% to close at $100.49 a share.

Chinese Internet company Baidu (BIDU) - Get Report rose 1.6% to $184.64 in after-hours trading Thursday, after it reported its fourth quarter results. The uptick in its share price occurred, despite posting a 2.6% decline in revenue to 18.21 billion yuan, or $2.65 billion, from 18.7 billion a year earlier, according to a Reuters report.

Analysts were expecting the Chinese web services company to report a decline in profits and revenue and that the company would still be struggling to recover from its setbacks in 2016. Those setbacks last year included a steep erosion to its margins relating to its local services and online video investments, as well as a regulatory probe into its ad placements. In addition, it faces ever growing competition from rivals Alibaba BABA and Tencent.

During the regular session, Baidu fell 0.74% to end the day at $184.64.
