Nokia’s stock soars to a record gain on record volume, for no apparent reason

Shares of Nokia Corp. powered up in very volatile and active trading Wednesday, enough for the Finland-based networking company to comment on the activity.

“Nokia is not aware of any material, undisclosed corporate developments or material change in its business or affairs that has not been publicly disclosed that would account for the recent increase in the market price or trading volume of its shares,” the company said in a statement.

The stock NOK, pared intraday gains of as much as 107.0%, but still soared 38.5% to close Wednesday at a 2-year high of $6.55. That was the biggest one-day percentage gain since it started trading in February 1991.

Trading volume spiked up to 1.14 billion shares, also a record, and well above the full-day average of about 47.3 million shares.

Nokia’s stock was halted five times for volatility, and was also halted once for news before the company commented on the stock movement.

Nokia’s stock was the second-most active on the New York Stock Exchange, behind only the 1.25 billion shares traded in AMC Entertainment Holding Inc.’s stock AMC, . AMC has been part of a group of stocks, including GameStop Corp.’s GME, , that have been skyrocketing as investors flocked to potential short-squeeze candidates.
