Worst Recommendations:

1) Robert W. Baird analyst Brian Skorney recommended an Underperform rating on Idenix Pharmaceuticals Inc (IDIX) on April  8, 2014, after the company announced that the data from its phase 1/II clinical trial for its IDX21437 nucleotide for the treatment of Hepatitis C was promising.

However, the analyst was skeptical regarding the safety of the drug’s under development, noting “We still believe a long road lies ahead fraught with risks.” He explained his Underperform rating, saying the “assets in development do not support the current valuation and provide little upside opportunity.”

Shares were $5.83 when Skorney made the recommendation and jumped to $24 three months later. Based on a 3-month horizon, Skorney lost a -308.0% return in profit for his Underperform rating on IDIX.

After Skorney’s position closed, Idenix Pharmaceuticals was acquired by Merck & Co. (NYSE: MRK) and is no longer an independently publicly traded company.

Brian Skorney has successfully made 32 ratings out of 56 total over the past year, earning a 57% success rate recommending stocks and a +2.4% average return per recommendation.

 

2) Cantor Fitzgerald analyst Irina Rivkind downgraded her rating on Pernix Therapeutics (NASDAQ: PTX) from Hold to Sell on January 6, 2014, after having concerns over a lawsuit in which the company was sued for breach of contract. The analyst anticipated “a negative reaction in the stock or potential dilution to shareholders from an equity financing event.”

When Rivkand made the recommendation, shares were priced at $2.22. Three months later, Pernix Therapeutics was priced at $5.04. Based on a 3-month horizon, Rivkind lost a -120.2% return in profit for her Sell rating on PTX.

Irina Rivkind has successfully made 57 ratings out of 85 total over the past year, earning a 67% success rate recommending stocks with a +18.5% average return per recommendation.

 

3) On September 10, 2014, Bank of America/ Merrill Lynch analyst Krish Sankar maintained a Buy rating on Sapphire supplier GT Advanced Tech (GTAT), but cut his price target from $22 to $19 after Apple announced they would not be using Sapphire for its iPhone 6.

Sankar did not expect the new iPhone 6 to have Sapphire, however he did believe Apple’s use of Sapphire in their devices is more of a matter of “when” than a matter of “if.”

Shares were $12.78 when Sankar made the recommendation. Before the 3-month position was closed, GT Advanced filed for bankruptcy and trading of the company’s stock (GTAT) on the NASDAQ is now currently frozen. Sankar lost a -97.7% return in profit for his Buy rating on GTAT.

Krish Sankar has successfully made 19 ratings out of 40 total over the past year, earning a 48% success rate recommending stocks with a -3.3% average return per recommendation.

 

4) On August 13,2014, Cowen & Co. analyst Jeff Osborne also covered GT Advanced Technologies (GTAT) with an Outperform rating and a $19 price target, citing that “Apple’s new products launch could serve as a near term catalyst.”

The analyst noted, “We see late 2015/early 2016 as being the end of the transitional period for GTAT as Apple revenue accelerates and solar polysilicon / ingot revenue normalizes and revenue recognition on material Hyperion revenue is achieved.” He continued, “ We note this range implies a ~19x multiple on our 2015 estimates, which is lofty, thus we expect the stock performance to be dependent on additional catalysts such as orders on the announced new products as well as on existing solutions.”

When Osborne made the recommendation, shares were priced at $16.59. As stated before, GT Advanced filed for bankruptcy before Osborne’s 3-month position was closed and trading of the company’s stock (GTAT) on the NASDAQ is now currently frozen. Osborne lost a -97.5% return in profit for his Outperform rating on GTAT.

In the past year, Jeff Osborne has successfully made 18 ratings out of 37 total, earning a 49% success rate recommending stocks and a -5.7% average return per recommendation.

 

5) Wunderlich analyst Irene Haas reiterated a Buy rating on BPZ Resources (NYSE: BPZ) with a $7.00 price target on September 23, 2014, after the company released an operations report on September 22, 2014.

The analyst pointed out the operations report contained good news and bad news, the good news being “that the CX15-7D development well at Corvina was completed earlier than expected allowing BPZ to spud the CX15-10D well on September 14, 2014 with completion scheduled for November 2014” and the bad news being “that the Corvina CX15-3D and Albacora A-21D are only producing at 36% of prior levels, suboptimal in our view. Related to this, production from 3Q14 will be lower than volume from 2Q14.”

Shares were $1.97 when Haas made the recommendation and dropped to $0.22 three months later. Based on a 3-month horizon, Haas lost a -88.3% return in profit for her Buy rating on BPZ.

Irene Haas has successfully made 23 ratings out of 77 total over the past year, earning a 30% success rate recommending stocks and a -15.9% average return per recommendation.
