Over the years, like many boomers, John and Sharon invested for their retirement in mutual funds and, in 2008, saw their retirement nest egg lose in excess of 50%. There was frustration over the limitations of the “buy and hold” strategy commonly used at the time and the lack of true management of their money to limit their losses by their money manager. In addition, previously unheard of events were unfolding, such as the failures of major Wall Street firms such as Bear Stearns, Lehman Brothers and AIG. It was clear the financial landscape had changed dramatically and they decided it was time to find a better way. Having extensive experience in economics and building complex information technology systems in a variety of industries, they embarked on building a solution that could search for and identify various repeatable trends that increased the probability of a positive return while reducing exposure to loss.
