Groupon's (Nasdaq: GRPN) stock is crashing only 20 days after the IPO boldly stepped out into the volatile marketplace. All eyes watched as the company defied expectations and traded at a profit for weeks, but alas, initial concerns may have been justified after all.

Since its debut on November 4th, the stock has traded comfortably above the $20 IPO price. That was until yesterday, when the stock fell over 10% and as of 12:00 today (Nov. 23) it has dropped more than 14.95% down to $17.11 per share.

So what happened? According to Henry Blodget, CEO and Editor-in-Chief of Business Insider it's anyone's guess. "It could be that some investors are hearing bad news about Q4. It could be that the underwriters have stopped aggressively supporting the price. It could be the broader market. Or all of the above. The bottom line is that folks aren't willing to pay as much for the stock as they were a few days ago."

At the same time, he notes, the company is transitioning from hyper-growth to profitable growth, a change that usually takes a toll on stock prices. "In my opinion, the IPO price was too high to account for that."

IPO market
The company entered the market after an extended period of zero IPO releases and poor results for those that had been released. Groupon's release and performance therefore drew a lot of attention.

Investors, venture capital firms, and tech startups viewed the company as a bellwether of future public offerings. Other IPOs-in-waiting followed the performance for signals it was safe to follow suit and enter the market.

Time will tell if Groupon will be trading steady at new and lower levels, if it will crash further, or if it will rebound.
