Only two companies appear daring enough to attempt initial public offerings this week as investors shy away from risky investments and buzz-worthy companies wait for the volatile market cloud to pass.

About a third of the IPOs expected last month postponed IPO plans or withdrew deals, and those that did make it to market had to offer deep discounts to investors as stock markets traded wildly. Two companies expected this week, Welsh Property Trust and Nobao Renewable Energy Holdings Ltd., will likely get a cold reception from investors, according to analysts who track the IPO market.
