Midday Report: Starbucks Hit With Downgrade; U.S. Stocks Climb

U.S. stocks spiked by late Tuesday morning as hopes grew OPEC members could agree on a production freeze when they meet in Qatar this weekend. Crude jumped above $41 a barrel on unconfirmed reports Saudi Arabia and non-OPEC member Russia have already agreed on terms. Starbucks (SBUX) - Get Report  was a drag on the Nasdaq after Deutsche Bank downgraded the stock to HOLD from BUY. The firm said the downgrade was a valuation call based on a $64 price target. Juniper Networks (JNPR) - Get Report slumped after cutting its forecast for its first quarter. The networking company said the weaker outlook was due to softer business demand and unfavorable timing of deployment from some telecom companies.
