回复：投资股票

For 8 years of investment duration, I can find you two products -

1) Market return (track S & P 500) and 100% principal protected.

For example, you buy it today with $10,000, Dow is 12,777; 8 years later, if Dow is up 80% cumulatively, you'll get $10,000+$8000 back to pay for your kid's tuition; if Dow is up 20% cumulatively, you'll get $10,000+$2000; if Dow is down (any number negative)cumulatively, you'll get $10,000+$0. 

2) Getting 5% first year and 2%+ (tracking with Fed's prime rate) in the rest of 7 years depending on Fed's prime rate; your principal is protected.The minimum guaranteed rate is 2% the estimated annual rate can be 5% (we are expecting Fed to raise up the rate in 2014)

You can buy these type of products from brokers. This is not the advertisement.
