As the stock market’s stormy weather continues, several initial public offerings are seeking the shelter of a delay.

Trustwave Holdings became the most recent to postpone its planned IPO. It was scheduled for today, Aug. 11, and set as a $100 million IPO with a market capitalization of $684 million at a price range mid-point of $16. The on-demand data security and compliance solutions company made the official announcement late Wednesday but did not offer any further comment on the matter.

Other digitally relevant delays were announced by 3D motion sensing specialist InvenSense Inc. and mobile marketing and payment services provider TIM w.e. SGPS SA. InvenSense was due to raise $99.8 million, while TIM w.e. SGPS SA expected $146.3 million.

The S&P 500 index has dropped nearly 17 percent over the past two weeks, driven by concerns over the U.S. economy.
