The Orocobre share price is up 4% to $7.40. This lithium miner's shares were given a boost this morning from a bullish broker note out of Ord Minnett. According to the note, the broker has upgraded Orocobre's shares to a buy rating with an $8.45 price target. The broker believes the company is well-positioned to benefit from strong lithium prices. It feels this will especially be the case if its merger with Galaxy Resources Limited ( ASX: GXY) completes successfully.
