and Equity Brief:

Stifel Nicolaus initiated coverage on shares of Intuitive Surgical, Inc.
(NASDAQ: ISRG). They issued a hold rating on the stock.

Stifel Nicolaus initiated coverage on shares of Johnson & Johnson (NYSE: JNJ).
They issued a hold rating on the stock.

BMO Capital Markets upgraded shares of Joy Global Inc. (NYSE: JOY) from an
underperform rating to a market perform rating. BMO Capital Markets now has a
$64.00 price target on the stock, up previously from $49.00.

Zacks reiterated its neutral rating on shares of Korea Electric Power Corp
(NYSE: KEP). They have a $13.00 price target on the stock. Zacks' analyst wrote,
"Korea Electric Power Corporation is the dominant player in Korea's electricity
sector. It continues to be well-positioned to capitalize on growth opportunities
in this market and to benefit from the industry restructuring initiatives of the
Korean government. Higher electricity tariff rates, higher electricity volume
sales, an improving overseas business and a recent regulatory approval for the
fuel cost pass-through mechanism will all add to the growth story. However, we
are taking a conservative and cautious view on the stock given the scenario of
foreign currency valuation loss, escalating fuel costs, the increased price of
purchased power and uncertainty surrounding pending regulatory cases. As such,
we maintain our Neutral recommendation on Korea Electric Power. "

Argus raised its price target on shares of Lowe's (NYSE: LOW) from $35.00 to
$38.00. They have a buy rating on the stock.

BMO Capital Markets downgraded shares of Laredo Petroleum Holdings Inc (LPI)
from an outperform rating to a market perform rating. Their analysts now have a
$22.00 price target on the stock, down previously from $27.00.

Oppenheimer initiated coverage on shares of The Medicines Compan (MDCO). They
issued an outperform rating on the stock and set a $35.00 price target. They
wrote, "Our positive stance is based on our view that Angiomax, MDCO's key
commercial asset, is worth $19/share alone, suggesting the market is
attributing little/no value to MDCO's pipeline, which consists of two
potentially promising Phase III assets. We look for Phase III data from
antiplatelet-agent Cangrelor by YE12/early 2013, and data from two Phase III
studies of antibiotic asset Oritavancin, being developed to treat ABSSSI, in
1H13, which we anticipate could serve as significant positive catalysts for the
stock. Our $35 PT is based on the average of our sum-ofthe-parts and DCF
analysis."

Zacks reiterated its neutral rating on shares of Allscripts Healthcare Solutions
(MDRX). They have a $13.00 price target on the stock.

Stifel Nicolaus initiated coverage on shares of Medtronic, Inc. (MDT). They
