Swedish media led by E24 is reporting of unusually high level of activitity in shares of industrial tooling and equipment manufacturer Atlas Copco (OMX: ATCO A, ATCO B)). Morgan Stanley made 14000 trades within a 15 minute period (16 trades per second) early in the morning with the A-share. The total volume far outpaced all other shares in the exchange and was mostly consisted of internal trades.
The experts hypothesized this action to be an error in algorithm based trading. Individual investors were certainly puzzled. Morgan Stanley's share of the trades made in Atlas Copco's B share was also high at around 40% for the day. The shares ended up 7% in a day of global rallying on news of extreme liquidity measures from major central banks.
