Sometimes an analyst issues a revised outlook or changes his/her rating but does not inform investors of the reasons behind the call. These typically move stocks on the call alone; the price target and outlook. However, some analysts provide detailed reasons behind the call; these are the outlooks that should be noted and used as part of your fundamental research. Therefore, I am taking a look at such outlooks and determining the best way to utilize the information.

After a five-year 90% loss shares of Alcatel-Lucent had a low rating by just about every analyst who covered the stock. But as it has rallied in the past few months, more and more analysts have begun to upgrade the stock, and a neutral from Citi is a big deal.

Citigroup stated its reasons for the upgrade were an improved carrier spending environment and lower bankruptcy risk following the company’s refinancing deal with Goldman Sachs. Shares of Alcatel rallied higher by 3% on Wednesday following this upgrade, and it’s very likely that more firms will follow the lead of Citi as Alcatel continues to restructure its large business.

Technology company Netsuite is now trading near all-time highs after being upgraded by Lazard to Buy. According to Lazard, the company’s cloud business should translate into strong earnings thanks to growth in e-commerce and in apps. The firm believes that the company’s recent investments will allow it to beat expectations for the current quarter and will force the company to raise guidance for the future.

This is quite a bullish call from the firm, on a stock that is trading with a price/sales of 16.46 and was recently downgraded by Goldman Sachs thanks to valuation-related concerns. Over the last few years it has been a great performer, but is very expensive compared to fundamentals. Therefore, I’d avoid this one.

It has been a rough couple years for metal mining companies, yet over the last month, shares of Platinum Group have rallied 42% and continued on Wednesday after being upgraded to Outperform. The firm is now expecting a price of $1.75, a large premium over its current price of $1.15.

Apparently, RBC believes the company has hit a gold mine, and although we don’t know yet, the potential for its Waterberg deposit could be fundamentally huge. The firm believes the deposit will continue to surface. This “surface” could result in resource expansion and open pit mining for the company. As a result, it’s a speculative play, but one that RBC believes is likely. I suggest further research on this company.
