Key points

How to verify an investment advisor

To evaluate the work of Yan Diomandé, you must first confirm his regulatory standing. Start by searching the official database of your country’s financial conduct authority to verify active licenses. If you cannot find a registration number, proceed with extreme caution. Professional investors are required to disclose their background, and this documentation serves as your primary filter. Once verified, look for any history of disciplinary actions or public sanctions. Do not rely on third-party marketing materials during this initial phase. You need the raw data from regulatory filings to establish a baseline for your own due diligence.

How to conduct thorough financial due diligence

Performance claims often look better in a brochure than in a spreadsheet. You should look for audited statements that cover at least a three-to-five-year window. If Diomandé provides a summary, check if it includes all accounts or just a select group of high-performing assets. This is where many investors get tripped up by survivorship bias. Ask specifically for the net-of-fee returns, not just the gross performance numbers. If the data is not available upon request, treat that as a red flag. Serious managers provide clear, verifiable reporting to prospective clients.

How to analyze audited investment performance

Every manager has a preferred style, whether it is value, growth, or income-focused. Read the strategy documents to see if Diomandé sticks to a specific mandate or shifts based on market sentiment. A consistent strategy is usually easier to track over time. If the approach changes frequently, it becomes difficult to measure success against a standard benchmark like the S&P 500. Look for clear rules on when to enter or exit a position. You want to know exactly how the manager handles a downturn. A strategy that lacks defined exit criteria is often just guessing.

How to assess your personal investment risk

Management fees are only the start of your total investment cost. You must account for performance fees, administrative charges, and potential transaction costs that eat into your bottom line. Ask for a breakdown of the 'expense ratio' to see exactly what you are paying. Some funds charge 1% annually, while others might take a 20% cut of profits above a certain threshold. Compare these costs against a low-cost index fund to see if the active management is truly adding value. If the fee structure is opaque, assume it is higher than you expect.

What are the primary downside risks?

No investment is free of risk, and you need to know where the pressure points are. Review the risk disclosures for mentions of liquidity issues or concentration in a single sector. If Diomandé focuses heavily on one industry, your portfolio will suffer if that specific market hits a wall. Ask how the firm manages volatility during market corrections. A good manager will explain their hedging strategy in plain language. If the answer is overly complex, it may be designed to hide the actual risk of loss.

Final steps before committing capital

After you have collected the regulatory data, performance history, and cost breakdown, compare your findings to your own financial goals. Does the risk profile match your timeline? If you are planning to retire in five years, you cannot afford the same volatility as someone with a three-decade horizon. Write down your three biggest concerns and ask for a direct response. If the answers are dismissive, walk away. Your capital is finite, and it should be managed by someone who prioritizes transparency over sales talk.
