Much of the buzz in the IPO market surrounded Facebook this week, as it headlined what was a slow stretch in IPO activity. Only two other companies were on the calendar and neither was able to complete its deal. Cancer Genetics (CGIX), which offers personalized genomic tests in cancer treatments, postponed its IPO on Thursday and Loyalty Alliance Enterprise (LAEC), a provider of mobile direct marketing and customer loyalty solutions in China, delayed its offering for another week. TIM w.e. (TMWE), a provider of mobile marketing, entertainment and payment services in Latin America, also postponed its IPO on Thursday. It was TMWE's second attempt at a public offering in nine months.
