A report from the New York-based short-selling firm Grizzly Research that it is shorting Raiffeisen's stock is behind the price drop.
According to Grizzly, the short-selling attack is motivated by the bank's exposure to the Russian economy and the risk that the bank has committed sanctions violations.
In short, short selling means that an investor bets on a fall in a share price by selling borrowed shares, hoping to buy them back before returning them to the owner at a lower price.
