I have a 401k plan with my company. I am planning to invest under the 401 k plan. There are plans like target 2050, s&p and others. There is one plan called the growth which holds stocks from Apple, google, Facebook and other top companies. The return on this seems to be 14% in an year and about 12% in 3 years. So would it be wise or rather how risky would it be to invest in this?
