Why I Sold Citi

I sold my CitiGroup (C) position today. For a very simple reason: stock is up 20% in four trading sessions. Now, I could've kept it anyway, if company was good. But come on, this is the worst big bank in the world! It doesn't seem to do anything right. I bought it in December when it was pressed down by secondary offer. I thought then that it might be a good bet on improving economy and that stock is more or less safe because company is officially backstopped by Government. And I might buy it back if it falls well below $4. But 20% in four session screams "Sell!".
