What “Biggest” and “Best” Mean
When we say biggest, we mean the firm manages a lot of money or has a huge number of clients. For example, in the US, advisers handled about $144.6 trillion in 2024, up from $128.4 trillion the year before.
When we say best, we mean the firm has a strong reputation, gives trusted advice, offers good investment options, and keeps clients happy. Many of these firms are also considered the best asset management firms. They are on lists of top wealth management firms and top brokerage firms.
If a firm is both big and best, it is worth paying attention to.
