The GBC Canadian Growth Fund is about to turn 20, and is boasting double digit average returns over its lifetime.

To October 31, the flagship fund’s average annual return since inception was 10.8%. In dollar terms, $100,000 invested in the fund on November 30, 1988 would have a market value of more than $750,000 today, the firm reports.

Montreal-based GBC Asset Management is the private client division of independent money manager, Pembroke Management Ltd., which manages the GBC Canadian Growth Fund and GBC North American Growth Fund.

GBC and Pembroke say they attribute the success of the company and their funds to their stable team of investment managers, a disciplined process of stock selection, and a fundamental philosophy of backing growing companies run by successful entrepreneurs with a large stake in their businesses.

“In the same way that we have the majority of our net worth invested in the same funds as our clients, we expect the owners of the businesses we invest in to have a large part of their net worth in the businesses they run. It keeps everyone’s interests in line.” said Jeff Tory, chairman of GBC Asset Management.
