Stock futures were mixed Thursday and bonds tumbled as Federal Reserve Chairman Jerome Powell reiterated the central bank's commitment to supporting the economy.
Here are some of the top movers during premarket trading on Thursday.
1. GameStop GME | Up 64%
Shares of GameStop (GME) surged more than 65% and resumed their unexpected rise from late-day trading on Wednesday.
The videogame retailer at the center of last month's Reddit-fueled buying frenzy more than doubled to close at $91.70.
TheStreet's founder, Jim Cramer, argues in his RealMoney.com column that the moves could be linked to action in the options markets.
2. AMC Entertainment AMC | Up 15%
Shares of theater chain AMC Entertainment (AMC) rose 14% as GameStop's surge boosted fellow Reddit favorite AMC's stock.
3. Moderna MRNA | Up 3.6%
Moderna (MRNA) stock traded higher even after the company reported a wider-than-expected fourth-quarter loss. Sales were almost double the estimates as it continued to forge ahead with the rollout of its COVID-19 vaccine.
On Wednesday, Moderna said it had made the initial doses of a new COVID-19 vaccine designed to better protect people against the South Africa strain and shipped them to the National Institutes of Health to start a clinical trial.
4. Wayfair W | Up 0.7%
Shares of Wayfair (W) rose even after the online retailer of furniture and home goods missed fourth-quarter revenue estimates and reported a drop in the number of orders.
5. Teladoc Health TDOC | Down 6.6%
Shares of Teladoc Health (TDOC) fell after the telemedicine provider after the closing bell reported a wider-than-expected fourth-quarter loss. Revenue doubled to $383.3 million.

Shares of Best Buy (BBY) dropped after the electronics retailer reported revenue and comparable-store sales that missed Wall Street estimates for the holiday quarter.
7. Plug Power PLUG | Down 5.7%
Shares of Plug Power (PLUG) slipped after the hydrogen fuel cell company reported a much wider-than-expected fourth-quarter loss and swung to negative revenue, but reported gross billings that beat analysts' expectations.
