Finding an individual or institutional consultant who can help you locate high-anxiety beneficial owners of publicly traded stocks outside the USA can be challenging. Here are some steps and suggestions:

1. **Financial Advisory Firms**: Look for global financial advisory firms that specialize in wealth management. Firms like Goldman Sachs, Morgan Stanley, and UBS often have international offices and consultants who might have insights into non-US markets.

2. **Investment Research Firms**: Companies like Morningstar, Bloomberg, and Refinitiv provide detailed analyses and reports on publicly traded stocks worldwide. Their analysts might be able to direct you to beneficial owners facing anxiety due to market downturns.

3. **Network with Industry Experts**: Attend international financial conferences, webinars, and seminars. Networking with professionals in these settings can provide leads to the consultants you seek.

4. **Professional Associations**: Reach out to professional associations such as the CFA Institute or the Global Association of Risk Professionals (GARP). They can connect you with members who have expertise in global markets.

5. **Consulting Marketplaces**: Platforms like GLG (Gerson Lehrman Group) and AlphaSights connect businesses with experts and consultants across various fields, including finance and stock market analysis.

6. **LinkedIn**: Use LinkedIn to search for consultants with expertise in international stock markets and wealth management. Look for profiles that mention experience with high-net-worth individuals or institutional investors.

7. **International Banks**: Contact large international banks with wealth management divisions. Banks like HSBC, Deutsche Bank, and Credit Suisse have global reach and may have the necessary expertise.

When contacting these resources, clearly outline your requirements and the specific nature of your inquiry to increase the chances of finding a consultant who can assist you.
