AMC has reached an agreement with investment bank B. Riley Securities and Citigroup Global Markets to act as selling agents, according to an SEC filing.

On Wednesday, however, AMC shares closed 95% higher on retail trading from Twitter and Reddit's WallStreetBets. This is despite an 8.5 million share dump from hedge fund Mudrick Capital, which bought and sold shares in the same day,according to Bloomberg.

AMC was one of the names that made headlines in January when retail traders on Reddit piled into stocks like GameStop to short squeeze hedge funds and cause them steep losses. And AMC says the rollercoaster ride may not be over just yet:

"We believe that the recent volatility and our current market prices reflect market and trading dynamics unrelated to our underlying business, or macro or industry fundamentals, and we do not know how long these dynamics will last."

AMC also recently launched a website, Investor Connect, in an effortto reach those online investorswho have boosted its stock --- offering a free large popcorn and invitation to special screenings for those who sign up.
