Republican presidential challenger Mitt Romney shed dozens of stocks and holdings in various foreign companies in the last 10 months, beefing up his cash reserves while maintaining an overall fortune as high as $250 million, according to personal financial disclosures he filed Friday.

The disclosure — required of presidential candidates — showed that the presumptive GOP nominee's net worth has not changed greatly since last September's financial disclosure, when he reported his assets were worth between $190 million and $250 million.

President Obama, meanwhile, reported last month that his assets are between $2.6 million and $8.3 million.
