Analyst Update: Marvell Technology Group Ltd., Alibaba Group Holding Ltd, and Amazon.com, Inc.

Analysts are weighing in on semiconductor stock Marvell Technology Group Ltd. (NASDAQ:MRVL), as well as online retailers Alibaba Group Holding Ltd (NYSE:BABA) and Amazon.com, Inc. (NASDAQ:AMZN). Here's a quick roundup of today's brokerage notes on MRVL, BABA, and AMZN.

• Credit Suisse raised its rating on MRVL to "outperform" from "neutral," and increased its price target to $17.50 from $13.50, sending the stock up 0.7% to $12.92. Marvell Technologies Group Ltd. has been a strong performer on the charts, adding 46.5% so far in 2016, but the brokerage bunch has been slow to give the stock credit. In fact, the majority of the analysts tracking MRVL maintain a "hold" or worse rating on the shares. Pessimism may be building among traders, too -- short interest on the stock popped by nearly 54% during the most recent two-week reporting period, though these bearish bets still represent just 2.6% of MRVL's available float.

• BABA has slipped 1.7% to $103.45 despite a price-target hike to $125 from $110 at SunTrust Robinson, which also reiterated its bullish "buy" rating on the shares. Meanwhile, Alibaba Group Holdings Ltd today announced a new payment system -- VR Pay -- that will allow users to pay for purchases with a nod of the head while using virtual reality goggles. BABA has added 75% from its February lows, but there is still plenty of room for an unwinding of lingering bearish sentiment to give the stock an extra boost. Specifically, more than 10% of BABA's total float is currently sold short, accounting for roughly six sessions' worth of trading, at the equity's average daily volumes.

• Yet another analyst is setting its sights on a four-digit stock price for long-time outperformer AMZN. Cantor Fitzgerald raised its price target on the stock to the $1,000 mark from $835, citing acceleration in e-commerce revenue growth, and noting that "Amazon is disproportionately benefitting from this trend." Amazon.com, Inc. also upped its music streaming game today, launching a new subscription service with prices starting at $3.99 per month for users who already own the company’s voice-controlled Echo speaker. Amazon Music Unlimited subscriptions are also available to Amazon Prime members who do not own an Echo, as well as non-Prime members, but at higher price points. AMZN has been flying up the charts in recent months, tapping a series of higher highs, so it's no surprise 90% of analysts rate the stock a "buy" or better. The shares were last spotted up 0.6% at $836.
