By Frank Holmes, CEO and Chief Investment OfficerNEW YORK ( U.S. Global Investors) -- It was an exciting and educational week. I was in Vancouver at the Agora Financial Investment Symposium speaking to hundreds of investors who are eager to learn how to grow and protect their wealth. This year's theme, "Innovate or Die," fit well with my presentation, as the conference challenged attendees to adapt their investment strategies just as empires and enterprises adjust to changing circumstances. When I wasn't behind the podium, I sat with the audience, soaking up new ideas from speakers, including Gloom Boom & Doom Editor Marc Faber, historian Niall Ferguson and Editor of Outstanding Investments Byron King, who surprised me and challenged my current way of thinking. Back at the office, our analysts and portfolio managers continue their daily meetings as always to discuss and digest the mountains of research that cross our desks each day. We question what we read, analyze statistics and hypothesize on what we see happening across the global economy. As much as emotions and biases take a role in investing, our goal is to make decisions not based on groupthink that discourages creativity, but founded on a collective wisdom that encourages critical evaluation of the economy and markets. Global investors constantly need to be watchful of individual biases, impaired thinking and emotional reactions that can have an adverse effect on a portfolio. That's why we created this weekly Investor Alert that thousands of readers have come to rely on. One of our values at U.S. Global Investors is to always be curious to learn and improve, and the Investor Alert was borne from a belief that shareholders want to understand the very subtle nuances of biases and misconceptions. My presentation attempted to address a few cognitive dissonances I see in the markets these days and I was pleased to have several attendees approach me afterward, remarking how they thought differently after seeing the slides. See previous presentations and be surprised. As much as I'd love to share all of the visuals here, in the interest of space, I selected only a few that I believe challenge the paradigms of investing.
