Alibaba's initial public offering today is the most hyped of its kind since Facebook's debut more than two years ago.
But just because sentiment is running in favor of the stock on the company's big day, doesn't mean everyone's sanguine about the company--or bullish on the stock
Here are some recent headlines that, for one reason or another, don't buy into the hype:
* Four-star fund manager David Rolfe at Wedgewood Partners explains to CNBC why he's avoiding the stock.
* CNBC's Jeff Cox explains why, despite its size and success, U.S. investors might want to be wary of the company.
* Even though Alibaba has worked hard to get counterfeiters off its e-commerce platform, experts think the company has a long way to go before its truly clean.
* Finally, there are some aspects to the company's structure that might make some U.S. investors think twice about owning it.
