TD Ameritrade set up trading limitations on AMC Entertainment Holdings’ shares, the retail brokerage’s website appeared on Friday.

Trading in the stock will be restricted to customers with own capital on hand and not borrowed funds, TD Ameritrade said, adding there may be some extra necessities on trading alternatives that expire on June 11.

The news comes as shares of AMC shuffled between gains and misfortunes on Friday morning after a rankling rally that left the organization’s stock up around 90% for the week.

AMC has been at the center of a second wave of purchasing by retail investors who have hyped the stock in forums like Reddit’s WallStreetBets, reviving the “meme stock” phenomenon that sent shares of video game retailer GameStop up 1,600% in January.
