Thornburg Investment Management Background 

Thornburg Investment Management was founded by Garrett Thornburg in 1982. Before founding Thornburg, he worked at Bear, Stearns and Co. He still owns 100% of Thornburg. The firm prides itself on being located far from the financial centers of the United States, as it claims that this physical distance allows the firm to be more objective and look at financial trends with a broader view. 

Thornburg Investment Management Client Types and Minimum Account Sizes 

Thornburg offers separately managed accounts to high-net-worth investors. The firm also offers a fairly extensive menu of mutual fund options available to all investors.

For Institutional Equity Separate Accounts, the minimum investment required ranges from $10 million to $100 million. The minimum for Institutional Fixed Income Separate Accounts can be anywhere from $1 million to $50 million.

For individual investors who want to invest in a mutual fund offered by the firm, the required minimum investment depends on the fund the investor chooses to invest in and the class of the fund shares. For a Class A share investor, the minimum investment required tends to be $2,500.

  • International ADR
  • International Growth ADR
  • Limited-Term U.S. Government

For mutual funds, Thornburg’s investment approach largely depends on which fund you choose to invest in.

The firm is also strict about selling as soon as price targets are met or the firm’s investment theses start to break down. Notably, the firm’s fund managers invest in the funds they manage. 

Equity funds at the firm are built on a stock-by-stock basis rather than by looking at broad sector trends. The firm believes that this ensures diversification and maximizes returns for investors.

What to Watch Out For

It’s important to note that while Thornburg as a registered investment advisor, it isn’t a financial advisor in the way some other firms are. The firm doesn’t work with individual investors to provide financial planning and assist with estate planning, college savings planning or financially navigating other major life milestones. It is strictly an investment advisor, focusing on providing discretionary portfolio management and other investment-related services.

The firm is also fee-based, so some advisors can earn commissions from selling financial products to clients. Despite this being a potential conflict of interest, the firm sia fiduciary. This makes it legally obligated to act in the best interests of clients at all times.

Thornburg also has a disclosure on its Form ADV. This disclosure relates to an issue where the firm failed to file voting rights notifications.

Opening an Account with Thornburg Investment Management

If you want to open an account at Thornburg, you can call the firm or send an email. There is also a form on the website where you can fill in your information. Make sure to select “individual investor” from the initial drop-down menu. There is a section on the form where you can leave a message to let the firm know why you are interested in working with an advisor.

Methodology We analyzed data on average expenditures for seniors, cost of living and investment returns to determine how many years of retirement a $1 million nest egg would cover in cities across America.

First, we looked at data from the Bureau of Labor Statistics (BLS) on the average annual expenditures of seniors. We then applied cost of living data from the Council for Community and Economic Research to adjust those national average spending levels based on the costs of each expense category (housing, food, healthcare, utilities, transportation and other) in each city. Using this data, SmartAsset calculated the average cost of living for retirees in the largest U.S. cities.

We assumed the $1 million would grow at a real return (interest minus inflation) of 2%. Then, we divided $1 million by the sum of each of those annual numbers to determine how long $1 million would cover retirement expenses in each of the cities in our study. Cities where $1 million lasted the longest ranked the highest in the study.
