Citigroup Should Hold Here
If the latter scenario unfolds, then C will press still lower and break 45.02, at which point the stock either could plunge towards a test of very major support at the Aug 2006 low of 42.91 or make marginal new corrective lows (set a bear trap) and reverse to the upside with a vengeance.
Right at this moment, my inclination is to expect C to hold here, and then to stage a rally towards 48-49, which will not represent a major bottom but a coordinate within the establishment of a prolonged bottoming phase.
