I have not done well in my investment life. When I first started investing in my 20's and newly married, I put $10,000 into the hands of a "Certified FInancial Planner"....He allocated the money into several different funds; a couple of mutual funds and one "oil-income limited partnership"....well, long story short after some years the $10,000 became $6,000 and I got discouraged and pulled the money out.
Flash forward about 20 years and I forget what year was the great recession but most of us lost 33-50% of our retirement funds in the stock market. When the market price of my townhome was at its highest, I was tempted to sell, but didn't because some realtor said, "why would you want to sell something which is appreciating 8% a year? Of course, immediately thereafter, the housing bubble burst and my home lost about 40% of its prior value. I know many people don't consider investing in the stock market or mutual funds gambling, but the fact is, no matter how much research and how many prospectuses you look at, you can lose your money. Heck, sometimes I think horseplayers who study racing forms are like investors doing research, but it's all still a crapshoot. Do you disagree?
