Top executives at Overstock.com Inc. (OSTK.O: Quote, Profile, Research) bought about $2 million worth of the online retailer's shares last week, in a sign of confidence as its stock recovers from a recent sell-off.

Chief Executive Patrick Byrne and his father, Chairman John Byrne, each bought 20,000 shares at around $48 apiece, according to a U.S. Securities and Exchange Commission filing on Friday.
The purchases came a year after Patrick Byrne bought $12 million worth of Overstock shares, which surged 250 percent last year, from a low of $17.90 on Feb. 9, 2004, to a high of $77.18 on Dec. 6. However, the stock fell 13 percent immediately after it reported earnings on Jan. 27.
