With 2012 just beginning, now's a great time to gauge how the stocks you're interested in are likely to do this year and beyond. By knowing what stock analysts and fellow investors expect from a stock, you'll be smarter about whether you should buy it for your portfolio -- or sell it if you already own it.

Today, let's take a look at Geron (Nasdaq: GERN). The small biotech took it on the chin in 2011, losing more than 70% of its value as it wrestled with controversy about its stem-cell research program. But now that the company has made a huge strategic decision to move away from stem cells, the big question is whether the company can retain investor interest long enough to work through its pipeline of drugs. Below, I'll take a closer look at what people expect from Geron and its rivals.

Will Geron bounce back in 2012?
Analysts certainly have very high hopes for Geron, with a price target that's quadruple what the shares currently go for. Yet they also realistically peg Geron's potential as a long-term play, projecting losses through 2012. Members of our Motley Fool CAPS community are neutral about the stock, giving it a mid-range three-star rating.

The big move that Geron made in 2011 was to give up its stem-cell research. By doing so, Geron hopes to avoid any further damage from controversies over stem cells. Along with Geron, Cytori Therapeutics (Nasdaq: CYTX) and Aastrom Biosciences (Nasdaq: ASTM) have also seen big volatility in their shares, as advances in stem-cell research seem inevitably to give way to concerns about whether the companies are viable investments.

In addition to getting out of a controversial area, Geron will also save millions in research costs, as it expects to cut almost 40% of its workforce as a result of the move. Moreover, if the company is able to sell its stem-cell division to another buyer, it could bring in extra cash, which would be useful for clinical trials going forward. With their own stem-cell programs, Pfizer (NYSE: PFE) or GlaxoSmithKline (NYSE: GSK) could find the old Geron program a useful addition.

Geron has a number of drugs remaining in its pipeline after the move. Imetelstat is currently involved in four phase 2 clinical trials for various types of cancer. But both imetelstat and fellow cancer drug GRN1005 aren't expected to show results until late this year at the earliest. That means investors will have to wait awhile just to see if the drugs have enough promise to proceed to phase 3 trials. In the meantime, you should expect volatility from Geron shares anytime the company announces even the smallest bit of news.
