More people believe Twitter may not be a good investment

An Associated Press-CNBC poll finds that Twitter faces skepticism from potential investors and the broader public ahead of its initial public offering.

The poll released Monday shows that 36 percent of Americans believe buying stock in the 7-year-old short messaging service would be a good investment, while 47 percent disagree.

Twitter plans to make its Wall Street debut this week.

Last May, ahead of Facebook’s IPO, 51 percent of Americans said the social network would be a good investment.

One in five Americans has a Twitter account, according to the poll. One in 10, say they don’t have an account, but they look at others’ Twitter feeds.

The telephone poll was conducted Oct. 25 to 27 by GfK Roper Public Affairs and Corporate Communications among 1,006 U.S. adults.
