Symantec

Symantec ( SYMC) is having a better year in 2012. Shares of the $13 billion computer security firm have rallied around 18% year-to-date, besting the broad market's performance by a slight margin. Much of Symantec's performance came in the late Summer, when the stock gapped up and started moving higher extremely quickly.

But that straight-up trajectory wasn't sustainable, so shares have spent the last couple of months consolidating sideways in a price channel. Sideways consolidation isn't a bad thing -- it just means that investors are trying to catch their breath after a big volatile run. With resistance coming in at $19.25, buyers have a pretty well defined signal that the rest is over for SYMC and another rally leg is beginning. I wouldn't recommend buying until then.

Remember, these setups all come down to supply and demand from buyers and sellers. After the huge push higher at the end of the summer, sellers started coming in at $19.25 -- it was a price where sellers were more eager to sell and take gains than buyers were to keep buying. That's why the breakout above $19.25 is a buy signal; a breakout indicates that buyers have gained enough strength to absorb all of the excess supply above $19.25.

Without that upside barrier, this stock should be able to keep running higher...
