Regional Banking ETF Put Volume Pops During Afternoon Trading

  Today’s tickers: KRE, CPN, PRGO, FITB, DPS, SMH & M KRE  - SPDR KBW Regional Banking ETF –  A large-volume debit put spread initiated on the SPDR KBW Regional Banking ETF this afternoon suggests one options investor is wary that the significant run up in the price of the underlying fund since the start of December could reverse course next year. Shares of the KRE, an exchange-traded fund that tracks the performance of the KBW Regional Banking Index, are up slightly by 0.10% to trade at $25.18 as of 3:30pm. The strategist responsible for the put spread may be building up downside protection, or alternatively, could be taking an outright bearish stance on the regional banking sector through March 2011. Shares in the fund rallied 14.25% during December so far to reach a 6-month high of $25.59 this past Wednesday. The put-spreader picked up 19,000 put options at the March 2011 $24 strike for a premium of $0.81 each, and sold the same number of puts at the lower March 2011 $20 strike at a premium of $0.16 apiece. Net premium paid to initiate the spread amounts to $0.65 per contract. Thus, the investor is prepared to make money, or realize downside protection, if shares of the KRE fall 7.3% from the current price of $25.18 to breach the effective breakeven point on the spread at $23.35 by March 2011 expiration. Maximum potential profits of $3.35 per contract are available to the put-spreader should shares of the underlying fund plummet 20.6% lower to trade below $20.00 by expiration day next year. The fund’s shares have not traded below $20.00 in more than a year.
