United Therapeutics has a market cap of $2.65 billion and an enterprise value of $2.44 billion. This stock trades at a cheap valuation, with a trailing price-to-earnings of 10.50 and a forward price-to-earnings of 9.46. Its estimated growth rate for this year is 44.5%, and for next year it's pegged at 4.3%. This is a cash-rich company, since the total cash position on its balance sheet is $503.46 million and its total debt is $273.37 million. After you back out the debt, this company has a net cash position of $230.09 million. The CEO just bought 9,000 shares, or about $466,000 worth of stock, at $51.44 to $52.12 per share. From a technical perspective, UTHR is currently trending above both its 50-day and 200-day moving averages, which is bullish. This stock recently bounced right off its 200-day at $50.06 a share and back above its 50-day at $51.28 a share. That bounce is quickly pushing shares of UTHR within range of triggering a near-term breakout trade. If you're in the bull camp on UTHR, then I would look for long-biased if this stock manages to break out above some near-term overhead resistance levels at $53.48 to $54.23 a share with 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 771,969 shares. If that breakout triggers soon, then UTHR will set up to re-test or possibly take out its next major overhead resistance levels $58.38 to $59 a share. Any move above $59 will then push UTHR into new 52-week high territory, which is bullish technical price action.
