The Stock Market - (Core)

The stock market is a massive financial network that allows people to buy and sell different companies.

The stock market is comprised thousands of companies, allowing anyone to buy or sell portions of companies.

Since many companies are huge, some having valuations in the $100,000,000,000’s, the stock market allows anyone to purchase and exchange small shares of these companies. These shares represent your (partial) ownership of these companies, and every share carries a monetary value.

On the stock market, companies are referred to as stocks.
A Company = A Stock

The Sole Gole:
The goal of investing is to invest in shares of companies you believe in, hoping that the value of the company increases, in turn causing your shares (holdings) to increase in value.

Throughout the year, we will discuss strategies on successfully analyzing good investments (stock choices)

Share Prices

Every share of a company has its unique price.

For example: Apple’s (AAPL) share price is $225/share. Chipotle’s (CMG) share price $56/share.

This means that to own shares of AAPL, you would need to invest $225 for each share you plan to buy.

Share Price Fluctuation:
Remember, to profit from the stock market, your shares need to increase in value.

This brings us to Share Price Fluctuation/Movement.

The value of any shares of stock are always changing. On one day they could go up 3%, on the next day they could go down 2.5%. Profit is never guaranteed, but you can take steps to improve your accuracy.

At the core, share price increases with company growth and success
We will go in-depth on the specifics in future sections

Did you know Elon Musk has 200 million shares of Tesla (TSLA)?
Companies often have hundreds of millions of shares total outstanding.

Important:
Do not compare two different stocks’ share prices. Different companies have different share prices, and comparing two different share prices of two different companies is useless.

For example, Costco (COST)’s share price is $900/share, but Apple (AAPL)’s is $225/share.
Does this mean Costco is a bigger company than Apple? No.

Market-Cap

Market-cap is an important piece of information to consider before any investment decision.

Market-cap represents the total value of the company, Market-Cap = Valuation.

Market Cap = share price * # of shares

Why Is It Important?
Market-cap determines the company’s size, based on what the stock market believes the company is worth. Paired with (*)quantitative data, it lets us measure the fair value of a stock.

*(will be covered when we discuss Fundamental Analysis)

A key thing to know:
Share price moves proportionally to market-cap
This means a +20% jump in share price means a +20% jump in market-cap

Comparing two different stocks’ market-caps is okay.

If a company has 1 million shares outstanding and the share price goes up from $100 to $120, the market-cap would increase as follows:

  • Initial market-cap: 1,000,000 shares * $100/share = $100,000,000
  • New market-cap: 1,000,000 shares * $120/share = $120,000,000

This shows how a change in the share price directly affects the market-cap.

Volume

Volume is the total # of shares traded within a day. Stocks with higher volume are more active and more well-known.

Volume isn’t all that important.

Volatitility

Volatility is important, though, as it measures a stock’s risk. A stock/company with a higher volatility moves more rapidly with bigger %change.

For example:
A stock with a lower volatility may see ~1-2% movement each day,
while a stock with a higher volatility could see >5% movement.

If you prefer your portfolio to aggressively grow VS remain stable, volatility is a key factor to consider.


Indexes

Indexes are an incredibly important part of the stock market.

Indexes generally measure the overall stock market’s performance, tracking hundreds of companies at once. You could almost think of them as a broad basket of stocks

The three major indexes are the: S&P 500, NASDAQ, and DOW
The S&P 500 tracks the 500 largest US companies.
The NASDAQ tracks technology and software companies
The DOW tracks the 30 biggest US companies

Indexes are steady and stable investments that rise slowly over time. They are a great alternative to cash if you dislike the risk associated with choosing specific stocks/companies.

We will continue to talk indexes and ETFs in the coming meetings
