Using Rapidminer to model trends in the financial markets

I know this was so last week but CitiGroup is buying Wachovia’s banking business.  Whether or not its a smart move remains to be seen but things *might* be turning around for this bad boy.  Any glimmer of hope is welcome news to long term shareholders, like myself.  What’ll make me feel really good is [...]
