Grasping these fundamentals is crucial for anyone looking to participate in the market.

To illustrate stock market concepts, we reference three prominent companies: Apple (AAPL), Google (GOOGL), and Amazon (AMZN).

A stock represents a share of ownership in a company. When you buy a stock, you become a shareholder and are entitled to a portion of the company's assets and earnings. Stocks are bought and sold on exchanges, with prices fluctuating based on supply and demand.
The stock market operates as a platform where buyers and sellers come together to trade shares of publicly listed companies. Prices are determined by supply and demand, and transactions are facilitated by brokers and exchanges. Market indices, like the S&P 500, track the performance of a basket of stocks.
Common investment strategies include buying and holding for the long term, diversification across different asset classes, and dollar-cost averaging, which involves investing a fixed amount of money at regular intervals. It’s important to align your strategy with your risk tolerance and financial goals.
“MoonshotScore rates a US-listed stock 0 to 100 — higher means stronger numbers. Most carry an older nine-factor score; the rest use five sector-relative pillars, re-ranked daily — common stocks and ADRs only. Funds, ETFs, warrants, units, SPACs, preferreds, and notes carry none. It is built for education and deeper due diligence, not financial advice.”
