Today’s tickers: ELNK, HBC, CECO, XLE, C, CMCSK, SWKS & ARNA ELNK Earthlink , Inc. – The internet service provider has experienced a 5% decline in shares today to $6.29. ELNK popped onto our ‘hot by options volume’ market scanner after one investor initiated a calendar roll. At the March 7.5 strike price 5,200 puts were sold for a premium of 95 cents each, while at the April 7.5 strike price 5,200 puts were purchased for 1.15 per contract. Maybe this investor sees Earthlink continuing to fall through next month, and therefore has rolled his in-the-money long-put position previously established in March into the next month’s contract. HBC HSBC Holdings Plc ADS – As with many other financials today, shares of HBC have rallied 4% to $27.05. One trade of interest occurred at the March 30 strike price where an investor appears to have purchased a straddle by picking up 7,500 calls for 15 cents apiece and 7,500 puts for 3.20 per contract. You may be thinking, given where shares are with today’s rally – why on earth would someone pay a combined premium of 3.35 in the hope that shares of the bank swing to either breakeven point located at $33.35 on the upside and at $26.65 on the downside? While it is possible that this investor’s motivation for the trade is to see profits amass on falling share price, we believe there may be a different explanation. Perhaps this trader had previously sold the options leaving him short and now he is buying back the contracts in order to close out his short position. It appears that about 7,500 of the existing open interest for calls and puts at the March 30 strike was built up between February 5th and 6th. Thus, we propose that this investor may have originally sold the straddle in February and is not buying it back before the March contract expires on Friday. CECO Career Education Corporation – Shares of the global education company have fallen 12% to $20.24. CECO is an on-ground provider of education at various levels and also has a significant presence in online education. The company edged onto our ‘hot by options volume’ market scanner after one investor established plays in the March and April contracts. At the March 22.5 strike price it appears that one investor initiated a credit spread by purchasing 5,000 calls for 38 cents apiece while selling 5,000 in-the-money calls at…
