The key drivers affecting Blackrock's stock price involve several factors, including changes in the macroeconomic environment, changes in interest rates, and changes in the company’s own performance.

The macroeconomic environment is a major factor affecting BlackRock’s stock price. This includes economic indicators such as GDP growth, inflation, unemployment, and consumer confidence. If the economy is doing well, this could increase demand for BlackRock’s financial products, positively affecting the company’s stock price.

Changes in interest rates can also have a major effect on BlackRock’s stock price. Interest rates can impact the demand for BlackRock’s financial products, and changes in interest rates will affect the cost of borrowing money to operate its business.

Blackrock is a publicly traded company, which means that its shares are owned by many different people and entities. As of March 2023, the largest shareholder of Blackrock is The Vanguard Group, with a 9.04% ownership stake. Following closely behind is State Street Corp at 4.21%, and Bank of America at 3.45%. The remaining of Blackrock’s shares are held by a variety of other institutional investors, as well as individual and retail shareholders.

Blackrock shares do pay a dividend, however, the yield is currently at 3.02%, while the Price/Earnings Ratio (P/E) stands at 20.55. The dividend yield is lower than the average for stocks in the SPX500 index, which stands at 1.90%. Nonetheless, investors may still find Blackrock's dividends attractive due to its strong market performance and relatively low P/E ratio.

Investors should keep in mind, however, that dividend yields can vary widely over time; it is therefore important to monitor the financial performance of Blackrock and its dividend payments on a regular basis. Additionally, investors should be aware of any changes in dividends or other factors which may impact Blackrock's payout prospects. Ultimately, whether or not to invest in Blackrock based on its dividends is an individual decision that should be made after careful consideration of the company's financials and outlook.
