BlackRock, Inc., founded in 1988, has grown to become the world's largest asset manager. Its journey is a testament to its strategic foresight, innovative approach, and ability to adapt to the evolving financial landscape. From managing $53 billion in assets in 1994, BlackRock has seen its assets under management (AUM) surge to an astounding $11,551 billion by 2024. This remarkable growth represents a compounded annual growth rate (CAGR) of 20%.BlackRock went public in 1999. Acquired Merrill Lynch Investment Management in 2006 and Barclays Global Investors in 2009.There are over 1,000 individual investment funds operated by Blackrock, and investors are able to purchase shares in both actively and passively managed funds.The main type of financial assets BlackRock invests in are equity securities typically in the form of stocks and shares, comprising the vast majority of the company’s portfolio. This is followed by fixed-income assets such as bonds, then cash, and alternative investments such as real estate and commodities. Over half of these assets are owned by clients residing in the Americas.
Following is Blackrock clients of whose assets they manage:
Following is the market share per Blackrock:
According to the data from MarketBeat as of 18 February 2025, 80.69% of BLK shares were owned by institutional investors – including institutions such as Merill Lynch, which merged with BlackRock in 2006. This means that over half of the Blackrock Inc shareholders are investment firms and asset managers, similar to BlackRock, which hold shares on behalf of their clients.According to data compiled by WallStreetZen as of 19 February 2025:
Investors from individuals to large institutions such as pension and hedge funds have flocked to this duo, won over in part by their low-cost funds and breadth of offerings. The proliferation of exchange-traded funds is also supercharging these firms and will likely continue to do so.
None other than Vanguard founder Jack Bogle, widely regarded as the father of the index fund, is raising the prospect that too much money is in too few hands, with BlackRock, Vanguard and State Street Corp. together owning significant stakes in the biggest U.S. companies.
"That’s about 20 percent owned by this oligopoly of three," Bogle said at a Nov. 28 appearance at the Council on Foreign Relations in New York. "It is too bad that there aren’t more people in the index-fund business.”
While bigger may be better for the fund giants, passive funds may be blurring the inherent value of securities, implied in a company’s earnings or cash flow. The argument goes like this: The number of indexes now outstrips U.S. stocks, with the eruption of passive funds driving demand for securities within these benchmarks, rather than for the broader universe of stocks and bonds. That could inflate or depress the price of these securities versus similar un-indexed assets, which may create bubbles and volatile price movements.
Another concern is that without the prospect of being part of an index, fewer small or mid-sized companies have an incentive to go public, according to Larry Tabb, founder of Tabb Group LLC, a New York-based firm that analyzes the structure of financial markets. That’s because their stock risks underperforming without the inclusion in an index or an ETF, he said. Benchmarks are governed by rules or a methodology for selection and some require that a security has a certain size or liquidity for inclusion.
Roughly 37 percent of assets in U.S.-domiciled equity funds are managed passively, up from 19 percent in 2009, according to Savita Subramanian at Bank of America Corp. By contrast, in Japan, nearly 70 percent of domestically focused equity funds are passively managed, suggesting the U.S. can stomach more indexing before market efficiency suffers.
That’s making regulators uneasy, with SEC Commissioner Kara Stein asking in February: “Does ownership concentration affect the willingness of companies to compete?”
“As BlackRock and Vanguard grow, and as money flows from active to large passive investors, their percentage share of every firm increases,” said Jose Azar in an interview. “If they cross the 10 percent threshold, I think for many people that would make it clearer that the growth of large asset managers could create serious concerns for competition in many industries.”
A mutual fund is an investment fund that pools money from many investors to purchase securities. The term is typically used in the United States, Canada, and India, while similar structures across the globe include the SICAV in Europe ('investment company with variable capital'), and the open-ended investment company (OEIC) in the UK.Mutual funds are often classified by their principal investments: money market funds, bond or fixed income funds, stock or equity funds, or hybrid funds.[1] Funds may also be categorized as index funds, which are passively managed funds that track the performance of an index, such as a stock market index or bond market index, or actively managed funds, which seek to outperform stock market indices but generally charge higher fees. The primary structures of mutual funds are open-end funds, closed-end funds, and unit investment trusts. Over long durations, passively managed funds consistently outperform actively managed funds.(? data)
Mutual funds have advantages and disadvantages compared to direct investing in individual securities. The advantages of mutual funds include economies of scale, diversification, liquidity, and professional management.[6] As with other types of investment, investing in mutual funds involves various fees and expenses.Mutual funds are regulated by governmental bodies and are required to publish information including performance, comparisons of performance to benchmarks, fees charged, and securities held. A single mutual fund may have several share classes, for which larger investors pay lower fees.Hedge funds and exchange-traded funds are not typically referred to as mutual funds, and each is targeted at different investors, with hedge funds being available only to high-net-worth individuals
The mutual fund industry has undergone tremendous change since 1945.The size and the number of funds available: What was a small industry (68, largely stock-oriented funds in 1945) with less than $1 billion in assets has become a giant, with assets now spread over a $7 trillion array of 8,000 stock, bond, and money market funds. (in 2019)
Stock funds in 1945 were largely large-capitalization blend funds that offered broad diversification, and for the most part, they were suitable to be held as the sole component of an investor’s equity investment portfolio. Today, “style box” investing has become the name of the game. Investors are able to slice and dice their equity fund investments into any number of styles and sectors.Fund holding periods have declined dramatically: From the 1940s until the mid-1960s, equity mutual funds were long-term investors that turned their portfolios over at an annual rate of less than 20 percent. They have gradually become short-term speculators that now turn their portfolios over at an annual rate of more than 100 percent.
The mutual fund industry’s ownership of Corporate America: In 1945, the mutual fund industry controlled barely more than 1 percent of all U.S. equities. Today, that figure is nearly 25 percent. The mutual fund industry has become the proverbial 800-pound gorilla. It could sit anywhere it wants at the corporate board table, but it rarely even attends the meetings.The costs of fund ownership have risen dramatically: Total mutual fund assets have increased 3,600-fold since 1945, but mutual fund fees and operating expenses have increased 6,600-fold in that same period—a stunning rise, particularly in an industry that is characterized by tremendous economies of scale.
