March 14 (Bloomberg) -- Trading of bullish Lubrizol Corp. options surged to the highest level in a year on March 9, before Berkshire Hathaway Inc.’s offer today to buy the world’s largest producer of lubricant additives lifted the shares 28 percent.
Call trading surged to 2,931 contracts on March 9, and open interest for the April $110 calls jumped to 2,654 from 41. A block of 2,168 April $110 calls traded for $2.35 each on March 9, data compiled by Bloomberg show. Lubrizol’s four-week average trading volume is 413. The April $110 calls advanced almost 11-fold to $24.70 today. The Wickliffe, Ohio-based company surged 28 percent to $134.68.
“That is more than suspicious,” said Ophir Gottlieb, head of client services at Livevol Inc., a San Francisco-based provider of options market analytics. “It looks like a naked purchase of calls, and that’s highly suspicious if not straight insiders trading.”
Berkshire, owned by billionaire Warren Buffett, today agreed to buy Lubrizol for about $9 billion in the investor’s second-biggest acquisition in the past five years. Berkshire will pay $135 a share in cash, 28 percent more than Lubrizol’s closing price on March 11, the Omaha, Nebraska-based company said in a statement today. The purchase includes an additional $700 million of net debt.
