A large block of Harman (HAR, news, chart, volatility) puts was sold yesterday, post-earnings. The initiator sold 3,000 November 15 puts for 15 cents, apparently closing a position opened last week and realizing a loss of almost $2 a contract. The stock closed Tuesday trading for $20.85 a share and up almost $4.00 from last week when it seems the position was opened ahead of the electronic equipment company’s October 29 earnings release. A similar position still exists in the December 15 puts.
