There are 14 stocks in the Standard & Poor's, including single-cup coffee company Keurig Green Mountain , health insurer Humana and Dr Pepper Snapple that are up 30% or more this year - but are starting to look a bit rich - according to analysts who cover them, according to a USA TODAY analysis of data from S&P Capital IQ. Each of these stocks have blown past analysts' average 18-month price targets - a big sign it might be time to lock in some profits.
