Analyst Update: Acadia Healthcare Company Inc, VASCO Data Security International, Inc., and Oasis Petroleum Inc.

Analysts are weighing in on healthcare firm Acadia Healthcare Company Inc (NASDAQ:ACHC), IT specialist VASCO Data Security International, Inc. (NASDAQ:VDSI), and oil-and-gas stock Oasis Petroleum Inc. (NYSE:OAS). Here's a quick roundup of today's brokerage notes on ACHC, VDSI, and OAS.

• ACHC received price-target cuts from UBS (to $55) and RBC (to $59) after the company announced Tuesday afternoon it had signed a $390 million deal to sell its U.K. facilities to BC Partners. Like analysts, traders don't seem particularly pleased with the news. The shares have surrendered 9.3% to $40.99 today, earlier hitting a three-year low of $37.96. Still, 12 out of 13 analysts tracking Acadia Healthcare Company Inc maintain a "buy" or better rating, without a "sell" recommendation in sight. As such, more bearish attention ahead would be no huge surprise, considering the stock has shed 37% of its value year-over-year.

• VDSI is getting smacked today, down 16.4% to $15, after announcing disappointing quarterly and full-year outlooks. The news was met with a downgrade to "neutral" from "buy" at Dougherty, which also removed its $20 price target. VASCO Data Security International, Inc. is due to report its final quarterly numbers next week, and it looks like traders have low expectations. Short interest on the stock currently represents nearly 12 sessions' worth of trading, at VDSI's typical daily volumes. Meanwhile, the shares are on track for their lowest close since March.

• After announcing on Tuesday the acquisition of a 55,000-acre property, and reporting a public offering of some 40 million common shares, OAS is swimming in bullish brokerage attention today. Specifically, the stock has received upgrades to "overweight" at Simmons and Capital One Securities -- the latter of which also added the stock to its "E&P Focus List" -- as well as no fewer than nine price-target hikes. The shares are trading 7.8% higher at $11.40 today, widening their year-to-date lead to nearly 55%, with a rise in oil prices also providing a lift. It looks like Oasis Petroleum Inc. may have also found an ally in its 30-day moving average, which contained the shares' pullback yesterday, and also ushered them higher through the early part of this year. The stock could get another boost should short sellers begin to cover their positions. These bearish bets climbed nearly 19% during the last two reporting periods, and now account for about 27% of OAS' available float.
