Asset management is the business of investing money on behalf of others: individuals saving for retirement, pension funds, insurers, endowments, governments and companies. Asset managers pool and invest that money through mutual funds, ETFs, separately managed accounts and private funds, and charge fees for doing so. The industry is enormous, and its biggest firms manage trillions of dollars each. Asset managers are the core of the buy side, and their trading decisions move markets every day.

The largest firm, BlackRock, has reported assets under management of more than $10 trillion in recent years, and the largest index providers have grown rapidly with the shift to passive investing. See Active vs Passive Investing.

How asset managers earn money#

FeeTypical form
Management feeA percentage of assets, from very low for index funds to over 1% for some active funds
Performance feeA share of gains, mainly in hedge funds and private funds
Expense ratioThe annual total cost of a fund, shown as a percentage
Loads and distribution feesSales charges on some mutual funds

Because fees are tied to assets, the business grows with markets and client inflows. Competition from low cost index funds has pushed average fees down for years.

The investment process#

  1. Research: analysts study companies, sectors and economies. See Valuation Basics.
  2. Portfolio construction: portfolio managers decide holdings and weights. See Portfolio Construction.
  3. Risk management: independent teams monitor exposures and limits. See Risk, Position, Loss and Drawdown Limits.
  4. Trading: buy side traders execute orders, often with algorithms. See Execution and Sales Trader.
  5. Operations: settlement, accounting and reporting. See Fund Accounting and NAV.
  6. Client service and distribution: reporting and raising assets. See Investor Reporting.

Fiduciary duty and regulation#

Asset managers usually owe a fiduciary duty to act in their clients' best interests. In the US, funds are regulated under the Investment Company Act of 1940 and managers under the Investment Advisers Act of 1940, both overseen by the SEC. In the EU, UCITS rules govern most retail funds. See Trading Regulators: SEC, CFTC, FINRA and NFA.
