One stock that's trading very close to triggering a major breakout trade is Radian Group ( RDN), which provides credit-related insurance coverage and financial services to mortgage lenders and other financial institutions. This stock has been on fire so far in 2013, with shares up a whopping 75%. If you take a look at the chart for Radian Group, you'll notice that this stock has been uptrending very strong for the last five months, with shares soaring higher from its low of $3.74 to its recent high of $10.95 a share. During that uptrend, this stock has been consistently making higher lows and higher highs, which is bullish technical price action. Shares of RDN have also been consolidating for the last month, with the stock moving between $9.26 on the downside and close to $11 a share on the upside. Since RDN is now trading just above $10.50 a share, it's quickly moving within range of triggering a major breakout trade. Traders should now look for long-biased trades in RDN if it manages to break out above some near-term overhead resistance levels at $10.67 to its 52-week high of $10.95 a share high volume. Look for a sustained move or close above those levels with volume that hits near or above its three-month average action of 9.59 million shares. If that breakout triggers soon, then RDN will set up to enter new 52-week-high territory, which is bullish price action. Some possible upside targets off that breakout are $15 to $18 a share. Traders can look to buy RDN off any weakness to anticipate that breakout and simply use a stop that sits just below some key near-term support levels at $10.03 to $9.76 a share. One could also buy RDN off strength once it takes out those breakout levels with volume and then simply use a stop right around $10.40 to $10.03 share. This stock is an absolute favorite target of the short-sellers, since the current short interest as a percentage of the float for RDN is extremely high at 25.2%. If that breakout triggers soon, then RDN could easily experience a monster short-squeeze that sends this stock screaming higher from current levels.
