Retired Cardiologist. Managed group retirement plan for 30 plus years(nearly 8 % average return with 19% drawdown during recent fincancial debacle) Now have turned over 90% of portfolio to professional manager who use very broad strategic asset allocation approach with only occasional tactical change. Have yet to acuire enough data to determine any long term results. Personal investments are mostly municipal bonds laddered when average reuturn was over 5%. Have been replacing matured individual bonds with MLPs so far but still searching for opportunities that fit.
