I’ve been talking mutual funds and index funds. They hold hundreds of stocks. Not 2-3. If you look at any growth mutual funds from 2000 on, which includes 9/11, the tech crash and so on, nearly all show 8% plus returns.Sure there is, but are you the one averaging 10% return per year over a 30 year period? Statistics are great, but in this discussion, they are basically worthless, because it's an average, meaning that some stocks like Apple grew while others didn't.
Now if you know which stocks are going to return 10% per year over the next 30 years than you should be investing not only your money but other peoples as well.
Your 20-to-30-year average also shows nothing, because most people, unless they purchased an Apple or Microsoft are not going to hold a stock over that long of a time period. People made fortunes owning Enron stock also, until the company went bankrupt. It’s all about getting in and holding on till the best time to sell, which unless you are a Warren Buffet type, most of us do not have that type of knowledge.
I looked at IPERS and they project average annual returns of 7%. So why is it so crazy for them to get 7 and mutual funds to get 8%.
One thing I didn’t know is that IPERS does not have a COLA.
