NEW YORK (TheStreet) -- The usual characteristics of momentum stocks include banking huge gains over the last 12 months, being significantly overvalued and having elevated price-to-earnings ratios. During a momentum phase, these stocks will typically have positive but overbought weekly chart profiles, with weekly closes above their five-week modified moving averages. At times these stocks can be out of favor and have significant downside corrections until momentum characteristics return.
As I explained on New Year's Eve, Apple (AAPL) shifted from being a momentum stock in 2012 to a value stock on weakness into April 2013. It then returned to momentum status in the second half of 2013.
As 2014 begins, there appears to be some profit-taking among the 8 momentum stocks I have been following.Here are my buy-and-trade parameters for these stocks.

The stock is below its 21-day simple moving average (SMA) at $559.74 with its 50-day and 200-day SMAs at $539.90 and $474.36. Apple has a positive but overbought weekly chart profile, maintaining momentum characteristics. The stock is above its five-week modified moving average (MMA) at $543.23 and its 200-week SMA at $427.32.
