1. What are 2 factors that determine how much investors put into stocks versus bonds?
2. Assume the long-term average return for bonds is 6% and for stocks is 10%, what is the effect of shifting some weight from bonds to stocks? imagine that you are 35 years away from retirement and you plan to contribute $10,000 per year for the next 35 years to your portfolio which is currently split equally between stocks and bonds (i.e. $5,000 goes into stocks and $5,000 goes into bonds each year). How much more would you have at your retirement in 35 years if instead of 50/50 split if you had invested 70% in stocks (i.e. $7,000) and only 30% in bonds (i.e. $3,000)?
