Shares of the company, known for its trademark beaver logo, rustic casual wear and Canadian-made leather goods, opened at C$11.50, down 4.2 percent from their initial public offering price of C$12. They slumped 16.3 percent from the IPO price to C$10.05 at 1110 EST (1510 GMT).

Roots raised C$200 million ($158 million) in the IPO.

Roots' bleak performance is the latest in a string of tribulations for the Canadian bricks-and-mortar retail industry. Besieged by competition from online players like Amazon.com Inc , profit margins for the sector have shrunk to under 5 percent.

"With the various problems facing retailers, there's concern about buying into what's essentially a retail store product," said David Cockfield, portfolio manager at Northland Wealth Management in Toronto.

Roots has 116 stores in Canada and four in the United States, as well as 109 partner-operated stores in Taiwan and 27 in China, according to its IPO prospectus. The company also ships to 54 countries through its website.

A Roots spokesperson could not be immediately reached for comment.

Roots' IPO price was reduced from the marketing range of C$14 to C$16, underscoring the company's modest growth outlook and broader challenges for brick-and-mortar retailers.

Roots, in its prospectus, said it had compound annual growth in sales of about 14 percent in 2014 to 2016.
