The universe of specialty retail stocks is not terribly large, measured either by number of companies or market cap. The entire sector has a market cap of about $310 billion, less than Apple Inc. (NYSE: AAPL) or Exxon Mobil Corp. (NYSE: XOM) alone. The companies represented in this group include pet supply stores, a bookstore chain, a DVD rental chain, office supply stores, a heavy equipment rental chain, an eyewear maker, and an auction house.

The companies we’re looking at include Office Depot, Inc. (NYSE: ODP), Office Max Inc. (NYSE: OMX), Staples, Inc. (NASDAQ: SPLS), Barnes & Noble, Inc. (NYSE: BKS), Coinstar, Inc. (NASDAQ: CSTR), Sotheby’s (NYSE: BID), Tractor Supply Co. (NASDAQ: TSCO), Titan Machinery Inc. (NASDAQ: TITN), PetSmart Inc. (NASDAQ: PETM), and Luxottica Group S.p.A. (NYSE: LUX).

Diversity aside, most of these stocks have very high implied gains, which means either that they are worth a second look or that there is no hope that any will ever hit their targets and that a lower target is soon to come. Which result will occur depends to a large extent on competitors in the same business, the overall economy, and whether consumers regain some of their lost confidence.

Office Depot, Inc. (NYSE: ODP) has a median target price of $4.00 from 13 brokers. Shares are trading today at $2.30, for an implied gain of $1.70, or 74%. Office Depot’s forward P/E is 28.5 and the company does not pay a dividend. The stock’s 52-week trading range is $1.75-$6.25, and at today’s price that’s about 31% above its 52-week low, posted earlier this morning, and 63% below the 52-week high.

Analysts didn’t expect much from Office Depot in the third quarter, and the company failed to deliver even that. EPS was break-even compared with an expected EPS of $0.01. Revenue also missed estimates. The implied gain in this stock is purely illusory when you consider its earnings and its immodest forward P/E.

Office Max Inc. (NYSE: OMX) has a median target price of $7.50 from 14 brokers. Shares are trading today at $5.10, for an implied gain of $2.40, or 47%. Office Max’s forward P/E is 7.39 and the company does not pay a dividend. The stock’s 52-week trading range is $3.90-$19.20, and at today’s price that’s about 31% above its 52-week low, posted earlier this morning, and 73% below the 52-week high.

Office Max reported that net income rose last quarter but revenue fell, as a result of cost-cutting measures. The company expects full-year revenue to be flat with last year. The company also plans to continue closing stores. There’s little long-term happiness in store for the company.

Staples, Inc. (NASDAQ: SPLS) has a median target price of $19.00 from 16 brokers. Shares are trading today at $14.69, for an implied gain of $4.31, or 29%. Staples’ forward P/E is 9.58 and the company pays a 2.8% dividend yield. The stock’s 52-week trading range is $11.94-$23.75, and at today’s price that’s about 23% above its 52-week low, posted earlier this morning, and 38% below the 52-week high.

Staples has been rumored as a possible buyer of either Office Depot or Office Max or both. The company’s market cap of $10.5 billion is about 10X the market cap of the other two combined, so such a deal is not out of the question. Staples’ target price is now lower than its 52-week high, a sign that analysts don’t expect a lot of growth. That could either spur the company to go ahead with an acquisition or cause it to sit on its hands.

Barnes & Noble, Inc. (NYSE: BKS) has a median target price of $15.50 from 4 brokers. Shares are trading today at $11.52, for an implied gain of $3.98, or 35%. B&N’s forward P/E is 33.87 and the company pays a huge 8.1% dividend yield. The stock’s 52-week trading range is $10.30-$12.65, and at today’s price that’s about 12% above its 52-week low, posted earlier this morning, and 9% below the 52-week high.

B&N is trying to keep up with Apple Inc. (NASDAQ: AAPL) and Amazon.com (NASDAQ: AMZN) in the e-reader/tablet market. The company is set to announce a new entrant in its Nook device family on Monday. Somehow, taking on the two biggest players in the market with a device that costs more than a comparable device from Amazon and has far less capability than an Apple iPad just doesn’t seem like a long-term winning strategy.
