Oil edges back up to $50 a barrel from six-month low

Oil recovered to just above $50 a barrel on Tuesday after touching a six-month low in the previous session, although high global production and concern over the economic outlook in China weighed on the outlook. The bounce came after a sharp slide in commodities on Monday due to economic worries, with a key global commodities price index sinking to a 12-year low. By 0849 GMT, Brent crude was up 57 cents at $50.09 and U.S. crude gained 61 cents to $45.78.
