Dec 6 (Reuters) - Liquidity Services Inc, an online auctioneer for surplus and salvaged assets, warned that it remained cautious about its overall outlook due to the volatility in the macro environment, sending its shares down as much as 15 percent.
Last month, Canadian peer Ritchie Bros Auctioneers Inc , which auctions industrial equipment and earns around half its revenue in the United States, posted a profit way below market estimates and said it remains cautious about the used equipment market in 2012.
Liquidity Services forecast first-quarter adjusted earnings of 23-27 cents per share.

Fourth-quarter net income rose to $3.1 million, or 10 cents per share, from $2.5 million, or 9 cents per share, a year ago.
Excluding items, the company earned 20 cents per share.
Revenue rose 11 percent to $80.7 million.
Analysts had expected fourth-quarter earnings of 19 cents per share on revenue of $79 million.
