Founded in 1988, McMahan Securities Co. LP is a broker-dealer located in Greenwich, Connecticut. They uncover companies early in their growth curve and create new and substantial investment opportunities for their clients. They focus their research solely on companies issuing convertibles. The companies they follow are often young, strong, growing firms. They tend to be those in need of capital that are properly positioned in their markets. Sometimes, they are companies that are not well known or recognized, making it difficult for them to successfully market an initial fixed-income offering. Instead, they issue convertibles, which are attractive to purchasers for their ability to be converted into equity, allowing participation in the company's rapid growth. Strategically, they look for securities with favorable risk/reward characteristics, those with a limited downside risk but a real opportunity to participate in the upside if the stock moves positively. Convertible securities can achieve both fixed income and equity type returns. They are a member of the NASD and the SIPC.
