Every day, the sun rises on Wall Street, and a plethora of professional analysts wake to issue new opinions on stocks. Here at the Fool, we use our "This Just In" column to examine some of these picks-- and the track records of the banks behind them -- so individuals can make better investing decisions.

In addition to following professional banks, anyone can use Motley Fool CAPS to monitor the collective opinions of more than 150,000 members, many of whom demonstrate better investing insight than published analysts do.

After spending the past year stuck at a two- and three-star ranking, enough top-performing CAPS members have turned bullish on Zoran (NASDAQ:ZRAN) recently to upgrade it to a more formidable four stars. A total of 196 members have given their opinion on the digital chip maker, with many of them offering analysis and commentary explaining the recent optimism.

Investors are warming up to the increasing potential of Zoran as it continues to bolster its position in several end markets. The chip maker holds a strong position in its two largest revenue-generating product lines -- digital TV and digital cameras -- and also competes with strong contenders including Advanced Micro Devices (NYSE:AMD), Broadcom (NASDAQ:BRCM), and NVIDIA (NASDAQ:NVDA) in mobile phones. It recently reported that fourth-quarter revenue grew compared with last year, while it also became more competitive.

As LCD glass maker Corning's (NYSE:GLW) recent earnings attest, the digital TV market is showing signs of strength and resilience, and Zoran reported boosting its digital TV market share in the U.S. to more than 30% while it looks forward to international expansion. While companies like China Digital TV (NYSE:STV) are expected to benefit from the growing use of digital TVs in that country, Zoran has high ambitions in Europe, other parts of Asia, and other emerging markets.

Investors also like Zoran's ability to win key customers in the digital camera space, a market that accounted for 37% of its fourth-quarter revenues. The market has also attracted big names, like Cisco Systems (NASDAQ:CSCO) last year with its purchase of Flip video manufacturer Pure Digital. To top it off, Zoran is backed by a debt-free balance sheet and holds a large portion of its market capitalization in cash.
