As a value-conscious investor, I’m always on the lookout for high-quality companies whose stocks are trading at discounted levels, and after a recent search of several industries, I came across three very attractive options. Let’s take a quick look at each, so you can determine if you should add one of them to your portfolio today.

1. Stantec Inc.

Stantec Inc. (TSX:STN)(NYSE:STN) is one of the world’s leading providers of comprehensive professional services, including engineering, architecture, interior design, landscape architecture, surveying, environmental sciences, project management, and project economics.

These multiples are also inexpensive given its estimated 12% long-term earnings growth rate.

Additionally, Stantec pays a quarterly dividend of $0.1125 per share, or $0.45 per share annually, giving its stock a yield of about 1.4%. Investors must also note that it has raised its annual dividend payment for three consecutive years, and its 7.1% hike in February has in on pace for 2016 to mark the fourth consecutive year with an increase.

Cameco Corporation (TSX:CCO)(NYSE:CCJ) is one of the largest uranium producers in the world, providing about 18% of the world’s total production from mines in Canada, the United States, and Kazakhstan, and it’s also one of the leading providers of nuclear fuel processing services.
