Shares of online jewelry auctioneer Bidz.com Inc. jumped Monday after an American Technology Research analyst began covering the stock with a “Buy” rating, citing Bidz’s “unique” business model, growth and fourth-quarter prospects.

Bidz shares rose $1.55, or 17.8 percent, to $10.25. The stock has moved between $4.90 and $22.50 since its shares listed on the Nasdaq in June, falling sharply in late November after a Citron Research report made several allegations against the company and stated that its business model is unsustainable.
