Professional Management

The volatility in today’s financial markets makes the ongoing review of your portfolio as essential as the initial fund manager selection. Our portfolio managers are continually monitoring and reviewing client’s portfolios in regards to performance, levels of risk, current market conditions, and world events. Through this continuous and disciplined process, Argentum can act immediately on any investment risk in your portfolio before it becomes a future investment loss.

Structured Portfolio

Your Argentum Advisor is always available to you to discuss and explain the latest investment strategies recommended by our portfolio management team. Based on an assessment of your investment objectives, time frame, appetite for risk, and desired returns, the Advisor will recommend a structured portfolio suiting your needs. Our portfolios include some of the most renowned investment institutions and management groups in the world, such as Fidelity, Schroder, JP Morgan, PIMCO, BlackRock, and more.
