LONDON, Sept 12 (Reuters) - Shares in oil major BP briefly spiked higher on Friday, a move which several tradersblamed on a likely human error or keyboard entry mistake,commonly known as a "fat finger" trade.
The flurry of activity in BP shares at 1041 GMT saw theshares jump 4.8 percent to 494.9 pence, adding around 4.3billion pounds ($7 billion) to the company's market value. At1101 GMT, they were trading 0.3 percent lower at 470.86 pence.
"(It) looks like a fat finger," said one London-basedtrader.
A London Stock Exchange spokesman said: "At 1141 (localtime), price threshold for BP was breached so it went into anautomatic five-minute suspension and then trading resumed asnormal."
But he added: "I don't have any information on what couldhave caused it at the moment."
