This stock, which shows up on a recent list of 10 Top Morningstar M&A Stock Picks for 2012, hasn't done much in 2012 with shares down by around 3%. NII Holdings has a market cap of $3.54 billion and an enterprise value of $5.24 billion. This stock trades at a cheap valuation, with a trailing price-to-earnings of 11.68 and a forward price-to-earnings of 13.10. Its estimated growth rate for this year is -24.6%, and for next year it's pegged at 5.3%.

From a technical standpoint, NIHD is currently trading below both its 50-day and 200-day moving averages, which is neutral bearish. This stock has been stuck in a nasty downtrend for the past few months and change, with shares dropping from over $35 to a recent low of $18.82 a share. Since hitting that low, the stock has started to find some buying support with shares now trading at just over $20 a share. If you're bullish on NIHD, I would look to buy some shares once it moves back above its 50-day moving average of $21.32 with volume. Look for volume that's near or well above its three-month average action of 3.04 million shares. If we get that action, then look to add to any long positions once NIHD breaks out above some near-term resistance at $22.19 a share with volume. I would simply use a mental stop on any long positions just below the 50-day if you buy off strength, or right around $18.82 a share if you get long off weakness.
