Exploitation refers to the act of taking advantage of someone or something for one's own benefit, often at the expense of the exploited party. This can occur in various forms such as economic exploitation, where workers are underpaid or overworked, or environmental exploitation, where natural resources are depleted for profit. Oppression, on the other hand, involves the systematic and pervasive mistreatment of a group of people, often based on their race, gender, or social class. This can manifest in the form of discrimination, marginalization, and denial of rights and opportunities. Both exploitation and oppression are forms of injustice that perpetuate inequality and harm individuals and communities. **

They can be traded separately from the underlying stock and can provide potential for additional profit if the stock price rises above the predetermined price. **

Yes, stocks can become worthless if the company goes bankrupt or if its value declines to the point where it is no longer traded on the stock market.

It is important for investors to carefully research and monitor the companies in which they invest to mitigate the risk of their stocks becoming worthless. **

The best time to trade stocks is during regular trading hours when the stock market is open. In the United States, this is typically from 9:30 AM to 4:00 PM Eastern Time, Monday through Friday. This is when there is the most liquidity and price movement in the market, making it easier to buy and sell stocks at fair prices. It is generally recommended to avoid trading during pre-market or after-hours trading unless you are an experienced trader, as these times can have lower liquidity and wider bid-ask spreads, which can lead to higher volatility and increased risk. **
