Fannie Mae and Freddie Mac stocks wobbled Monday after a near-meltdown last week, as the market mulled a weekend plan offering a lifeline for the mortgage finance firms from the US Federal Reserve and Treasury. Freddie Mac's shares shot up as much as 26 percent then fell eight percent before steadying in late morning trade with a modest gain of two percent at 7.90 dollars at 1420 GMT. AFP Photo/Paul J.
