Orlando is a professional engineer by trade but uses mathematics on a daily basis and has worked on trend analysis of stocks, indices and bonds for the last 20 years. His aim is for a long term portfolio gain of 3% PA IN EXCESS OF THE S&P 500. The return over the last 20 years has been 1.5% above the S&P 500 (much reduced by corrections in 2000 and 2008). He got out early in both of the last bull markets, but got back in too soon in both. Orlando uses seeking alpha to refine his investing techniques and likes many of the contributors.
