Amex Has 21 Firms for Start-Up Market: The American Stock Exchange named 21 companies lured from the over-the-counter market to trade on its new market for start-up firms. Companies in the new market, scheduled to begin trading on Wednesday, have lower financial standards than now needed to qualify for the nation’s second-biggest stock exchange. The Amex is billing its Emerging Company Marketplace as a forum for growing companies to gain exposure and raise capital. The Securities and Exchange Commission approved the new market last week, despite concerns that the volatile nature of untested company stocks could prove risky to small investors.
