Individual investor for last 30 years. I am interested in maximizing retirement returns. Have used strategies with Vanguard's ETFs with great success. Now interested in global emerging markets (VWO) and specific country ETFs including those for Mexico (EWW), Brazil (EWB) and China. I am willing to invest within periods of no more than one year to two years. Also believe that energy independence is necessary for U.S. to maintain global leadership. Interested in oils and natural gas ETFs including FCG and solar companies both domestic (First Solar) and foreign (Yinglii Solar).
