3 Stocks Down More Than 30% Today

U.S. stocks are higher today, as Wall Street celebrates the July jobs report. However, among the names bucking that trend are digital printing company Electronics For Imaging, Inc. (NASDAQ:EFII), fiber-optics concern Applied Optoelectronics Inc (NASDAQ:AAOI), and grocery company Natural Grocers by Vitamin Cottage Inc (NYSE:NGVC). Here's a quick look at what's moving shares of EFII, AAOI, and NGVC.

EFII Stock Crashes on 2Q Delay

EFII stock is getting hammered today, after the firm had to postpone its second-quarter 10-Q filing and announced an accounting investigation. Electronics For Imaging stock has dropped 43% to trade at $27.01 -- a new four-year low -- with EFII the worst percentage loser on the Nasdaq right now, and on the short-sale restricted (SSR) list.

Citing potentially months of uncertainty for EFII, Morgan Stanley downgraded the shares to "underweight" from "equal weight," and sliced its price target by $14 to $28. Additional downgrades could be in store, with six of eight analysts harboring "buy" or better opinions.

AAOI Stock Nosedives on Sales Guidance

Last seen trading down more than 32% at $66.65, Applied Optoelectronics stock is the second-worst percentage loser on the Nasdaq right now, after the firm unveiled a lackluster revenue forecast. As such, Northland Capital downgraded AAOI stock to "underperform," while Piper Jaffray cut its price target to $87 from $90. AAOI shares are also on the SSR list, and are testing support atop their 80-day moving average, after touching a record high just last week.

However, plenty of near-term options traders are likely cheering the equity's drop. Its Schaeffer's put/call open interest ratio (SOIR) of 1.84 sits in the 96th percentile of its annual range, suggesting short-term option players have rarely been more put-heavy during the past 12 months. 

NGVC Stock Hits Record Low, Leads NYSE Laggards     

Natural Grocers By Vitamin Cottage stock is the worst percentage loser on the New York Stock Exchange right now. After the firm reported lackluster quarterly earnings and cut its fiscal-year guidance, NGVC stock was last seen trading down 32% at $5.71, just above its early afternoon record low of $5.51. No fewer than three brokerage firms cut their price targets on NGVC stock, including a drop to $8 from $12 at Deutsche Bank. 

Prior to landing on the SSR list today, Natural Grocers was a favorite among short sellers. Short interest on the stock accounts for 22.82% of its available float, and would take nearly 20 sessions to buy back, at NGVC's average pace of trading.
