In the case of Internet fax and communications firm j2 Global (Nasdaq: JCOM), more investors in the CAPS community have recently turned positive on the stock -- enough, in fact, to push its rating from four stars to the (highest possible) five-star ranking. So what's the story behind this communal upgrade? Let's tap the various resources of CAPS to find out.

Certainly, a nearly 30% drop in j2 Global's share price over the past six months has affected how investors feel about the company. While the company has seen some impact from the economy as many of its credit-exposed clients cut back on fax services, some investors see the resulting sell-off as overdone. The company has also stepped in to snap up more of its own shares, putting a plan in place to buy up to 5 million shares.

Indeed, j2 Global still holds a sizable moat against competition because it has not only integrated all its communications services, but also provides them over a proprietary network. To match this advantage, potential competitors like Microsoft (Nasdaq: MSFT) or business services giant IBM (NYSE: IBM) would have to tie up with telecoms like AT&T (NYSE: T), Verizon (NYSE: VZ), or Qwest (NYSE: Q).
