(LDK Solar story updated for Tuesday close)NEW YORK ( TheStreet) -- Few solar stocks have attracted as much recent optimism as LDK Solar ( LDK), with recent price targets from LDK bulls suggesting the stock will double in value. On Tuesday morning, a notable bear take on the Chinese solar stock surfaced, as Collins Stewart recommended a sell on LDK. Notably, the sell recommendation from Collins Stewart came on the same morning as Brean Murray initiated coverage on LDK Solar at a buy. In the last week of February, Kaufman Brothers initiated coverage of LDK Solar at a buy with a price target of $24. Needham & Co. recently moved up to a $23 price target on LDK Solar. LDK Solar shares dipped below $12 on Tuesday at the close for the first time since January. LDK shares closed trading with a value of $11.94, or a loss of 1.9% on the day -- among the bigger losses in the solar sector on a bullish day for equities, though trading volume was typical for the Chinese solar company. For every bull there is a bear in the same way that for every buyer there has to be a seller. Just look at First Solar ( FSLR). In the case of LDK, the bulls and bears depart over many issues, including the impact of Italian solar subsidy revisions, pricing in the wafer market, the impact of LDK's plans to vertically integrate, the value of its planned polysilicon business IPO, and the competitive threat posed by GCL-Poly, which has set its sights on dominating the solar wafer market.
