Mackenzie Growth Team

We look for innovative, secular growth businesses that offer products and services that make the world better, cheaper, and faster.

Philosophy and process

The Mackenzie Growth Team aims to deliver superior performance over a full market cycle by investing in high-quality, innovative businesses that are growing faster than the economy and have sustainable competitive advantages. 

The Team believes that true value creation comes from innovations that make customers’ lives better, faster, and cheaper. The objective is to hold companies that have a place within the world as they see it changing in the future. The Team believes their investment edge lies in the ability to look through temporary problems and buy into price weakness because of the work they do to confirm their conviction in the long-term future for their companies.

They believe having a price discipline adds value to the investment process. The valuation process is based on discounted cash flow analysis using the Team’s own models, which means the Team understands the specific assumptions underlying their price targets. This process provides a foundation on which buy and sell decisions are made. The Team’s singular focus is on the US mid cap space. Being a small and focused team provides the nimbleness that allows for efficient decision making.

Morningstar Star Ratings reflect performance of Series F as of August 31, 2021 and are subject to change monthly. The ratings are an objective, quantitative measure of a fund’s historical risk-adjusted performance relative to other funds in its category. Only funds with at least a three-year track record are considered. The overall star rating for a fund is a weighted combination calculated from a fund’s 3, 5, and 10-year returns, as available, measured against the 91-day treasury bill and peer group returns. A fund can only be rated if there are a sufficient number of funds in its peer group to allow comparison for at least three years. If a fund scores in the top 10% of its fund category, it gets 5 stars; if it falls in the next 22.5%, it receives 4 stars; a place in the middle 35% earns a fund 3 stars; those in the next 22.5% receive 2 stars; and the lowest 10% receive 1 star. For more details on the calculation of Morningstar Star Ratings, see

FundGrade A+® is used with permission from Fundata Canada Inc., all rights reserved. The annual FundGrade A+® Awards are presented by Fundata Canada Inc. to recognize the “best of the best” among Canadian investment funds. The FundGrade A+® calculation is supplemental to the monthly FundGrade ratings and is calculated at the end of each calendar year. The FundGrade rating system evaluates funds based on their risk-adjusted performance, measured by Sharpe Ratio, Sortino Ratio, and Information Ratio. The score for each ratio is calculated individually, covering all time periods from 2 to 10 years. The scores are then weighted equally in calculating a monthly FundGrade. The top 10% of funds earn an A Grade; the next 20% of funds earn a B Grade; the next 40% of funds earn a C Grade; the next 20% of funds receive a D Grade; and the lowest 10% of funds receive an E Grade. To be eligible, a fund must have received a FundGrade rating every month in the previous year. The FundGrade A+® uses a GPA-style calculation, where each monthly FundGrade from “A” to “E” receives a score from 4 to 0, respectively. A fund’s average score for the year determines its GPA. Any fund with a GPA of 3.5 or greater is awarded a FundGrade A+® Award.
