Market participants have told Reuters that some Wall Street institutional investors are ramping up complex options trades that let them bet the shares will fall while keeping a lid on potential losses if they instead gain.
Cinema operator AMC Entertainment Holdings, which almost doubled in value again last week, rose 18.5%, while Microvision, a developer of laser beam scanning technology, climbed 7.1%.
Data shows AMC has been the top traded stock among clients of brokerages Fidelity and Freetrade, used heavily by amateur and individual investors playing with their own money.
On trading-focused social media site Stocktwits, message volume related to AMC – a barometer of interest in the stock – rose 3.3% on Monday.
Among other meme stocks, BlackBerry’s U.S. listing was up 8.6% and videogame retailer GameStop Corp and headphones maker KOSS rose 6.6% and 12.1%, respectively.
