First up this week is Travelers ( TRV), the $25 billion insurance company. Travelers has spent much of 2012 forming a bullish ascending triangle setup -- a trade that broke out in early August. Now, though, a throwback in shares is giving investors a second low-risk chance to buy this stock. Put simply, an ascending triangle is a pattern that's formed by a horizontal resistance level and uptrending support. The buy signal comes when shares push up above resistance. While that obviously already happened for TRV when shares moved above $64, the return back to test that former resistance line (the throwback I mentioned a minute ago) is a good thing for traders. >>5 Rocket Stocks Worth Buying This Week That may seem surprising -- after all, shares have been sliding -- but a throwback gives TRV the chance to confirm the strength of its newfound support level at $64. The ideal entry point comes on a bounce off of $64. While the bounce means that you're sacrificing a few points of profits, it also greatly reduces the risks that TRV will slip through $64. If you decide to be a buyer here, I'd recommend a protective stop just below the 50-day moving average.
