Six percent is "very conservative"? Where on earth are you getting THAT??
You're also confusing average rates of increase, which does not take into account the swings in the market and how those swings impact the actual portfolio performance in real dollars.
I couldn't care less if you're a BTITD kind of guy, it takes all kinds. But you need to understand math better if you're selling investments on "average rates of return" because you're not being honest with your clients.
In general, I support the concept of BOY, etc. Is it perfect? Of course not. But selling on 'average rates of return' is worse.
Here's something that I got from one of the books on being your own bank. It illustrates the concept with such clarity that it's undeniable...
Year 1 market is +100%
starting balance 10,000 ending balance 20,000
Year 2 market is -50%
starting balance 20,000 ending balance 10,000
Year 3 market is +100%
starting balance 10,000 ending balance 20,000
Year 4 market is -50%
starting balance 20,000 ending balance 10,000
This is an average rate of return of 25%, but you started with the same amount of money that you ended up with...and probably be less because of sales charges, commissions and the rest of it. But you've still seen a 25% average increase.
You bash the guy for saying a 6% return is conservative and then proceed to use a completely unrealistic model to prove a point. I'm not arguing for either model, but how many times has the market (a balanced portfolio) lost 50% in a given year let alone twice in a 4 year period?
