BlackRock (BLK) stock: Winston Score, insiders and Congress trades
BlackRock is the world's largest asset management company. It manages money on behalf of pension funds, governments, insurance companies, and everyday investors through mutual funds and exchange-traded funds (ETFs). Its iShares brand is the largest ETF provider in the world, giving millions of people low-cost ways to invest in stocks and bonds. BlackRock earns money primarily by charging a small percentage fee on the assets it manages — the more money it oversees, the more revenue it collects. It operates globally, with clients across North America, Europe, Asia, and beyond, and currently manages over $10 trillion in assets. Its technology platform, Aladdin, is used by other financial firms to manage risk, adding a software-like revenue stream on top of its core business. The main risk is that falling markets shrink the value of assets under management, which directly reduces the fees BlackRock collects.
