I am currently a retired Aerospace Engineer. I am married with three children and eight grandchildren. I was born in San Francisco, CA in 1949 and moved to Newport News, VA in 1951 where I lived until I went to college. By God's grace, I received a B.S. degree from Virginia Tech (1972), a M.S. degree from Caltech (1973), and a M.A. - Biblical Studies degree from Birmingham Theological Seminary (2013). I worked at Pratt & Whitney (1973-1986) and CFD Research Corporation (1987-2008).
Now in retirement and trying to preserve my life savings, I currently have a strong interest in tactical asset allocation strategies, and have studied them extensively. I have developed a number of tactical strategies involving the periodic trading of ETFs and, more recently, mutual funds. These strategies have been backtested mainly using Portfolio Visualizer and ETFreplay software. The goal is to earn 10-15% annually with no negative years, and to have maximum drawdowns of less than 10%, preferably less than 5%. The strategies include purchasing a limited number of funds with the highest growth and lowest volatility, and minimizing risk using moving average, dual momentum, and risk parity methods. I have developed strategies for equity as well as bond assets.
I am a patent litigator with a background in physics and electronics. I enjoy studying quantitative, rules-based investment methods through rigorous backtesting and numerical analysis. I believe that patterns exist in the market that benefit trading -- the challenge is finding them!
Individual investor. On double secret probation for commenting on SA articles, especially for pointing out that a portfolio that an RIA was using as an example of the kind of great advice he would provide had a drawdown of over 60%.
