Analyst Update: Amazon.com, Inc., Devon Energy Corp, and Relypsa Inc

Analysts are weighing in on e-tail stock Amazon.com, Inc. (NASDAQ:AMZN), oil-and-gas stock Devon Energy Corp (NYSE:DVN), and drugmaker Relypsa Inc (NASDAQ:RLYP). Here's a quick roundup of today's brokerage notes on AMZN, DVN, and RLYP.

• Last month Bernstein set a brow-raising $1,000 price target on AMZN, while MKM Partners last week said Amazon.com could become the largest U.S. company in just a few years. Today it's Oppenheimer singing the e-commerce company's praises, raising its price target to $930 from $780, citing increased profitability in its Amazon Web Services unit. Still, Amazon.com, Inc. is down 0.4% at $723.70. Options volume is also running well below the intraday average, despite rather muted premiums on near-term options, according to AMZN's Schaeffer's Volatility Index (SVI) of 20% -- just 4 percentage points from an annual low. In other news, Amazon Restaurants has launched free one-hour delivery on Prime Now in Atlanta and Miami. 

• Ahead of the company's shareholders meeting tomorrow, DVN this morning received a price-target increase to $40 from $37 at Raymond James -- right in line with the stock's average 12-month price target of $38.66. Moreover, 82% of covering analysts recommend buying Devon Energy Corp. While the stock is still far removed from its year-over-year breakeven mark of $62.50, the shares have been strong recently, outperforming the S&P 500 Index (SPX) by 45 percentage points during the past three months. Today, DVN is up 3.4% at $38.84 on pace for its best close since Dec. 4. 

• A downgrade to "underweight" from "equal weight" at Morgan Stanley has RLYP down 3.6% at $19.53 -- though the stock's 200-day moving average is holding up as support. It's been an up-and-down year for the stock, which currently sits 31% below breakeven in 2016. As such, short interest on Relypsa Inc still sits at all-time highs, with close to 15 million shares sold short.
