Reuters Exclusive: Waddell is mystery trader in market plunge

(Reuters) - A big mystery seller of futures contracts during the market meltdown last week was not a hedge fund or a high-frequency trader as many have suspected, but money manager Waddell & Reed Financial Inc, according to a document obtained by Reuters.

Waddell on May 6 sold a large order of e-mini contracts during a 20-minute span in which U.S. equities markets plunged, briefly wiping out nearly $1 trillion in market capital, the internal document from Chicago Mercantile Exchange parent CME Group Inc said.

The e-minis are one of the most liquid futures contracts in the world, providing holders exposure to the benchmark Standard & Poor's 500 Index. The contracts can act as a directional indicator for the underlying stock index.

Regulators and exchange officials quickly focused on Waddell's sale of 75,000 e-mini contracts, which the document said "superficially appeared to be anomalous activity."

More than a week after the incident, it was still not clear what impact the unusual trading in the futures contracts had on the broader meltdown in the stock market.

Waddell manages the $22.1 billion Ivy Asset Strategy fund, which is well-known for hedging with equity index futures when manager Mike Avery, who is also chief investment officer at the company, feels uneasy about the market.

The Asset Strategy fund has dropped 2.76 percent this quarter, compared with a 0.80 percent decline in the S&P 500, data from Lipper Inc, a unit of Thomson Reuters Corp show. more...
