Another area of concern is that Groupon's potential rivals have other revenue streams aside from the deals business. These include advertising, hardware, software, search, Web content and a host of other services.

Groupon has to make its business work and can't skip a beat, where a Google or Amazon can leverage other areas of their business to offset any potential deal drawback. If nothing else, they could just steal Groupon's traffic for their advertising-supported initiative.

These are just a few concerns that investors have had over the past couple of quarters. And we have yet to even address the "less than stellar" track record of the company's founder Eric Lefkofsky. In fact, some have even suggested a "spotty history" as described by investorplace.com -- a history that includes accusations of racketeering (later withdrawn), as noted in a Fortune article, plus bankruptcies, lawsuits and accusations of "creative accounting" from previous businesses under his supervision.

When you put these dynamics together, it is hard to muster up any confidence in the framework of Groupon. As investors continue to separate themselves from the stock, at this rate it will be a surprise if Groupon is still around by this time next year absent some significant fundamental changes.
