A phenomenon erupted in January involving mostly novice retail traders pushing up the share prices and options of certain listed companies heavily shorted by hedge funds to make them lose money as part of a push against perceived Wall Street greed.
These traders are coordinating their actions on social media sites such as Reddit and have inflicted hefty losses on short sellers of stock in companies such as bricks and mortar games retailer GameStop and cinema chain AMC Entertainment creating extreme price swings in the process.
