Individual investors are starting to come back to stocks, and market participants hope upcoming IPOs for some major companies will accelerate the process, The Wall Street Journal reports.

Twitter, Hilton Worldwide and Chrysler Group plan on coming to the market this fall.

Twitter has hired investment banks to manage a possible November IPO, according to The Journal. Hilton and Chrysler have registered for IPOs, though Chrysler's could come undone by a fight between its owner Fiat and its main union.

In addition, Alibaba Group, China's biggest e-commerce company, reportedly is working on a U.S. IPO.

"You think about the forthcoming IPOs of Twitter or Alibaba, that's creating a lot of buzz among individual investors," Jason Katz, a private wealth adviser at UBS, tells The Journal. "Investors are clamoring for IPOs of products and services that they're familiar with."

To be sure, given Facebook's IPO debacle last year, some individual investors are wary.

"After what happened with Facebook, there is now additional fear of IPOs," Nick Fosco, an engineer and stock investor in Arlington Heights, Ill., tells The Journal.

Comparing two of the planned IPOs, Forbes contributor Carol Tice writes, "the online buzz about Twitter's IPO is huge. But another IPO announced the same day might be a safer bet — the largest hotel chain, Hilton Worldwide."

She says, "for those who're skittish about investing in a stock [Twitter] that could turn into another Groupon, Hilton is everything Twitter is not: old, established, diversified and rich in hard assets."
