"Big Print in Citi (C) after the Jan 4 straddle..." (C)

Swell.

"...trades at $1.01, 20000X on PHLX. Shares are up 2 pennies at $4 and it looks like a seller initiating the trade, perhaps looking for the stock to hold around these levels through yearend. Implied volatility in Citi is around 37 and probing its 52-week lows."
