His advisor is telling him that the rule of 72 yields 12% per year (double in 6 years). If he wants to believe his advisor isn't trying to hoodwink him, that's his deal. He probably also told him, "I can tell that you are not only a powerful man, but a good looking one." LOLNever use the past eight years to try and predict the next 25 years. That is short term thinkg and no one can predict that far out. The best thing to do is take the past 60 or 70 years and use that to TRY to predict the future.
You must not that Zero interest rates are going to have a tremendous effect on your returns. You cannot expect good returns in that environment.
As for your Financial Advisor. I suspect he is a guy who tells you what mutual funds to invest in. If you pay him for his time that is best, but if he is getting a commission from the funds you chose, than lose him, his interests are not aligned with yours. Besides he didn't know what the rule of 72 is and he thinks you can make 10% returns, which is BS. If he is that good he should be running a hedge fund making billions of dollars, and most of the guys who make that money in hedge funds cheat to some degree as well.
In today's environment I am happy to make 2-3% on my 401k money and be able to sleep at night knowing it is not at much risk. Sure it is horrible return on capital, but with the government/Fed keeping interest rate down at zero, it is what it is. Think of all the old people who used to live off of CD's at the bank getting 6-7% a year, they have essentially been put in the poor house by these policies.
Moral of the story is, be safe not greedy, it is you and your families future.
