Analyst Upgrades: Ollie's Bargain Outlet, Aquinox,  Delta

Analysts are weighing in on discount retailer Ollie's Bargain Outlet Holdings Inc (NASDAQ:OLLI), drugmaker Aquinox Pharmaceuticals Inc (NASDAQ:AQXP), and airline issue Delta Air Lines, Inc. (NYSE:DAL). Here's a quick roundup of today's bullish brokerage notes on OLLI, AQXP, and DAL.

• Wall Street newcomer OLLI received a bevy of bullish brokerage attention this morning. Chiming in on the stock were Jefferies, J.P. Morgan Securities, KeyBanc, and RBC -- which all gave OLLI the equivalent of a "buy" rating and set their respective price targets in the $23-to-$24 range, never-before-seen territory. Credit Suisse, meanwhile, was a bit more cautious, initiating coverage with a "neutral" recommendation and a $20 target price. After a quick pop on its first day of trading -- which included hitting a record peak of $22.99 -- Ollie's Bargain Outlet Holdings Inc has shed 6% since its July 16 close at $21.15, and currently rests at $19.86.


• Friday was a big day for AQXP -- which popped nearly sixfold, thanks to some well-received drug data. The stock is back at it this morning -- up 140% at $25, and fresh off a record high of $25.87 -- following a price-target hike to $14 from $3 at Cowen and Company, and news that Baker Bros. Advisors has taken a 39.8% stake in Aquinox Pharmaceuticals Inc. Additional price-target hikes could be on the horizon, which may translate into more gains. Currently, the consensus 12-month price target of $5 stands at a steep discount to current trading levels.


• Raymond James boosted its price target on DAL to $58 from $53, representing expected upside of 25% to Friday's close at $46.35, and a move into uncharted waters. Technically speaking, the stock is down roughly 4.3% year-to-date at $47.06, and has recently run into trouble near the $47 mark -- an area that served as support in mid-May. Option traders have been rolling the dice on a breakout, though. At the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX), DAL's 50-day call/put volume ratio of 6.97 sits in the 99th annual percentile. Simply stated, calls have been bought to open over puts at a faster clip just 1% of the time within the past year. Separately, Delta Air Lines, Inc. said it has reduced the number of flights to Dubai, due to growth on Gulf carriers.
