Analyst Upgrades: NVIDIA Corporation, Oracle Corporation, and Salesforce.com, inc.

Analysts are weighing in on tech stocks NVIDIA Corporation (NASDAQ:NVDA), Oracle Corporation (NYSE:ORCL), and Salesforce.com, inc. (NYSE:CRM). Here's a quick roundup of today's bullish brokerage notes on NVDA, ORCL, and CRM.

• Canaccord Genuity upgraded NVDA to "buy" from "hold," and lifted its price target by $5 to $35 -- in territory not charted since late 2007. Earlier this month, NVIDIA Corporation reported blowout earnings, sending the shares to a multi-year high of $31.94. Today, NVDA is up 1.5% at $30.25, and a short squeeze could help the stock resume its journey to higher highs. Short interest ramped up by 28.7% during the past two reporting periods, and now represents nearly six sessions' worth of pent-up buying demand, at NVDA's average pace of trading. 

• Not even a week after a negative note from Morgan Stanley, ORCL is basking in the glow of some bullish brokerage attention, up 2.6% at $38.27. Goldman Sachs added the equity to its "conviction list," and lifted its price target by $2 to $47 -- which would mark a record high. Near-term option traders aren't so upbeat, it seems, as the stock's Schaeffer's put/call open interest ratio (SOIR) of 1.10 stands higher than 92% of all other readings during the past year. In other words, short-term option players have rarely been more put-heavy. Technically, ORCL has surrendered 15.5% in 2015, but recently bounced off support at its 50-month moving average. Off the charts, Oracle Corporation will host its annual shareholder meeting on Wednesday.

• CRM is up 0.5% at $76.01, following a price-target hike to $90 from $80 -- in uncharted territory -- at RBC. Salesforce.com, inc. also has a big day coming up, with the company's quarterly earnings slated for release after Wednesday's close. Heading into the report, option traders have displayed a healthier-than-usual appetite for bullish bets. The stock's 10-day call/put volume ratio on the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX) sits at 3.01 -- in the 67th percentile of its annual range. CRM has moved higher in the session after earnings in each of the past three quarters.
