Stock Market Investing Basics

Aug 10, 2025

Overview

This lecture introduced the basics of stock market investing, including how the stock market works, the power of compound interest, and how much wealth can be built over time with simple strategies. Students set up virtual accounts to practice buying stocks and explored different growth scenarios based on real historical data.

Stock Market Basics

  • The stock market allows you to buy and sell ownership (shares) in companies online through stock exchanges.
  • When you own a stock, you own a small part of the company; if the company grows in value, so does your share.
  • Major stock markets include the New York Stock Exchange, NASDAQ (mainly tech companies), Tel Aviv Stock Exchange, and others.
  • Stock "indexes" like the S&P 500 or NASDAQ are baskets of many top companies; you can invest in the entire market with one purchase.

The Power of Compound Interest

  • Banks offer low interest (≈2% per year); the stock market has historically averaged 10% (S&P 500) or higher (15%+ for NASDAQ).
  • Compound interest means the money you earn also starts earning money, creating exponential growth over time.
  • Small amounts invested regularly in the stock market can grow into large sums over decades.
  • Example: $1,000 invested at 10% for 50 years becomes $117,000; at 15% (NASDAQ average), it becomes over $1,000,000.

Investment Scenarios & Planning

  • Students played with calculators to see how regular contributions and different growth rates impact future wealth.
  • The earlier you start investing, the more compound interest works in your favor.
  • It’s possible to reach significant goals (travel, car, pilot license, $1M by age 40) with consistent monthly saving and investing.

Practical Steps: Virtual Stock Trading

  • A virtual stock trading account simulates real investing with fake money to practice buying and selling.
  • To buy a stock: enter the company name or ticker, choose “buy,” select the number of shares, set order type (market), and submit.
  • The buying process is very similar when investing real money.

Key Principles & Mindset

  • You don’t need to be good at math, have a lot of time, or start with a lot of money to succeed in the stock market.
  • Focus on building consistent habits; your “money personality” (spender vs. saver) impacts your investing approach.
  • Stock market investing is not gambling; historically, markets rise 71% of the time.
  • Most wealth is built by patient, long-term investing in proven indexes—not risky bets.
