Each of these companies, Palatin Technologies Inc (AMEX: PTN), UR-Energy Inc (AMEX: URG), and Vantage Drilling Company (AMEX: VTG), have picked up big increases in share valuation recently.

History has taught me that any run up is going to have its days when the long-term shareholders of a stock want to come in and sell a few shares and take a little profit; it’s normal. Of course daily speculators take their rewards at random, sometimes all at once, but the ‘Faithful’ just want a little reminder of why they have stuck around so long, so they sell a few shares at a higher price; and may even use it to aggregate if a dip happens.

Look at drug maker Palatin Technologies… its start of Phase IIb trials for its drug to treat sexual dysfunction in woman literally sent the shares skyrocketing. I think it can hold the gains. Here’s why: a look of biotech and pharma companies are working on drugs that will receive a warm reception on FDA approval, but other companies, like Palatin, are working on “Much Needed” drugs that will immediately attract a ‘Global Market’ and their approval will ‘Make Bank’. Palatin was trading in the $0.80 range before the Phase IIb announcement and it shot up to nearly $1.30 before a little profit taking set in. It is currently trading in the $1.22 range, a gain of 52.5% since the news. There are virtually no short sellers of this stock.

And UR-Energy, the uranium mining concern, has had a nice ‘bump’ recently, traveling from $1.47 in early June to its current price of $1.59, a gain of 8% in three weeks. Nice. I think this stock is undervalued: Nuclear energy isn’t going to go away. It may change, and even drastically after the Japanese disaster, but countries and utilities will still need uranium, regardless of the political climate. There are virtually no short sellers of this stock to apply downward pressure.

And Vantage Drilling Company has had a good two weeks: bouncing back with strong support from a dip. Falling from $2 to $1.65 in mid June, the stock is currently trading in the $1.80 range, a two week gain of 9%. If you look at an annual chart of Vantage Drilling, you’ll see that its ‘bounce backs’ have a lot of strength and generally recover any losses in valuation. The short/float ratio is less than normal and the Company has positive, triple digit sales projections. I think it can easily retake $2 in the near term.

I haven’t, don’t, and do not intend on holding any of the companies mentioned in this article.
