Occupy Wall Street Protest

Arab Spring: In 2011 there were a series of protests spread across several Middle Eastern and North African countries, including Tunisia, Egypt, Libya, and Syria. These events led to political instability and regime changes in some of the nations.

Fukushima Daiichi nuclear disaster: On 11 March 2011, an earthquake and tsunami struck Japan, causing a catastrophic failure at the Fukushima Daiichi nuclear power plant. The incident led to a nuclear meltdown, the release of radioactive materials, and a significant impact on Japan's energy policies. As you can imagine, this had a ripple effect on global financial markets.

Occupy Wall Street: Another protest movement emerged in New York to highlight income inequality, corporate influence, and social injustice. It quickly spread to other cities in the United States and eventually worldwide.

LinkedIn home

If you're a white-collar worker like me, you probably spend too much time trawling LinkedIn. But if you're not, LinkedIn is a professional networking platform that helps people connect with other professionals, find jobs, and stay updated with industry news.

As of June 2023, HCA Healthcare has a market capitalization of $75B followed by Apollo Global Management with a market capitalization of $43B. Of course, this is subject to change and you should check for the latest data.

What is the IPO process?

The IPO process is different for every stock exchange.

However, it typically involves several similar steps. These include selecting an investment bank as the underwriters, preparing a registration statement with the Securities and Exchange Commission (SEC), and conducting a roadshow to generate interest from potential investors.

Once the IPO is launched, shares are priced, allocated, and eventually traded on a stock exchange, allowing the company to raise capital and provide liquidity to early investors.
