How Stock Exchange Works in South Carolina

What Stock Exchange Is and How It Operates

Stock Exchange is a physical or digital marketplace where shares of publicly traded companies change hands between buyers and sellers. In South Carolina, you won't find a major stock exchange headquartered here—the largest exchanges operate in New York and other financial centers—but you can participate in stock trading through brokers, investment firms, and online platforms based anywhere in the United States.

When you buy a stock, you own a small piece of a company. When you sell it, you transfer that ownership to someone else. The exchange itself is the venue where that transaction happens, setting the rules, recording the trades, and ensuring both sides hold up their end of the deal. Prices move based on supply and demand: more buyers than sellers pushes the price up; more sellers than buyers pushes it down.

The largest U.S. stock exchanges are the New York Stock Exchange (NYSE) and the NASDAQ. Both operate electronic trading systems that match buy and sell orders in seconds. Smaller exchanges exist, but most individual investors in South Carolina trade through one of these two or through over-the-counter (OTC) markets, which handle stocks that don't meet the listing requirements of major exchanges.

Key Takeaways

• Stock exchanges are marketplaces where company shares trade between buyers and sellers, with prices set by supply and demand.
• You cannot trade directly on an exchange yourself; you must use a broker or investment firm licensed to execute trades on your behalf.
• The NYSE and NASDAQ are the two largest U.S. exchanges, but most individual investors access them through online brokerage accounts.
• Trading hours are typically 9:30 a.m. to 4 p.m. Eastern time on weekdays, though after-hours trading exists with different rules and wider price spreads.
• Stock prices fluctuate constantly based on company performance, economic conditions, and investor sentiment, so past performance does not predict future results.

How to Open a Brokerage Account and Start Trading

To trade stocks, you need a brokerage account—a relationship with a licensed firm that executes your buy and sell orders on the exchange. Most brokerages operate online and let you open an account in minutes by providing your name, address, Social Security number, and employment information. They verify your identity and may ask about your investment experience and financial situation.

Once your account is open and funded, you can place an order to buy or sell a stock by entering the company's ticker symbol (a short code like AAPL for Apple or MSFT for Microsoft), the number of shares, and the type of order. A market order buys or sells immediately at the current price. A limit order lets you set a maximum price you'll pay to buy or a minimum price you'll accept to sell; the trade only happens if the stock reaches that price.

Popular brokerages used by South Carolina residents include Fidelity, Charles Schwab, E*TRADE, TD Ameritrade, and Robinhood. Many charge no commission per trade, though some may charge fees for certain services like wire transfers or account maintenance. Compare fee structures before opening an account, as they vary significantly.

Understanding Stock Prices and Market Hours

Stock prices on major exchanges update in real time during regular trading hours, which run from 9:30 a.m. to 4 p.m. Eastern time, Monday through Friday. The market is closed on weekends and federal holidays. During these hours, millions of shares trade every minute, and prices shift constantly based on news, earnings reports, economic data, and investor decisions.

After-hours trading occurs from 4 p.m. to 8 p.m. Eastern time and involves a smaller number of traders. Prices can swing more dramatically during after-hours sessions because fewer buyers and sellers are active, so the bid-ask spread (the difference between what buyers will pay and what sellers will accept) widens. Most individual investors avoid after-hours trading because of this volatility and lower liquidity.

A stock's price reflects what buyers and sellers agree it is worth at that moment. If a company announces strong earnings, the stock often rises because investors expect better future performance. If the company misses expectations or faces bad news, the stock often falls. Economic conditions, interest rates, and broader market trends also influence individual stock prices.

Different Types of Stock Orders and Execution

When you place an order, you choose how specific you want to be about price and timing. A market order guarantees execution but not price—your order fills at whatever price the stock is trading at when your order reaches the exchange, which could be slightly different from the price you saw on your screen. Market orders are best for liquid stocks (those with high trading volume) where the price is unlikely to move much between your click and execution.

A limit order lets you set a price ceiling (for buys) or floor (for sells). If you place a limit buy order for 100 shares of a stock at $50, your order only fills if the stock drops to $50 or lower. The trade may never happen if the stock never reaches your price. Limit orders are useful when you want to avoid overpaying or when trading less liquid stocks where prices can swing more.

A stop-loss order automatically sells your shares if the price drops to a level you set, protecting you from larger losses. A stop-limit order combines both: it triggers a limit order once the stock hits your stop price. These tools help manage risk but can also lock in losses if the stock rebounds after hitting your stop price.

Costs, Taxes, and What Happens When You Sell

Most online brokerages charge zero commission per trade, meaning you don't pay a fee to buy or sell stocks. However, you may encounter other costs: wire transfer fees to move money in or out, account maintenance fees (rare now), or fees for certain research tools or premium features. Read your broker's fee schedule before opening an account.

When you sell a stock for more than you paid for it, you owe capital gains tax on the profit. If you held the stock for more than one year, it's taxed as a long-term capital gain, usually at a lower rate than ordinary income. If you sold within one year, it's a short-term capital gain, taxed at your regular income tax rate. South Carolina does not have a separate capital gains tax, but the federal government does, and rates vary based on your income level.

Your broker sends you a 1099 form each January listing all your trades and gains or losses from the previous year. Keep records of what you paid for each stock (your cost basis) and when you bought and sold it, because you'll need this information to calculate your tax liability accurately.

Risks and Why Stock Prices Fall

Stock prices can fall for many reasons, and there is no may provide they will recover. A company's earnings may disappoint investors. A competitor may release a better product. The economy may slow, reducing consumer spending. A natural disaster, lawsuit, or leadership change can shake investor confidence. Broader market downturns—recessions, financial crises, or geopolitical events—can drag down even strong companies.

If you buy a stock at $100 and it falls to $50, you have lost half your money on paper. You only lock in that loss if you sell. If you hold and the stock recovers to $100 or higher, you break even or profit. But there is no rule that says it must recover. Companies go bankrupt, and shareholders can lose their entire investment.

Diversification—owning stocks in different companies, industries, and sectors—reduces the impact of any single stock's decline. Many beginners start by buying index funds or exchange-traded funds (ETFs) that hold dozens or hundreds of stocks, spreading risk across many companies rather than betting on one.

How to Research Stocks Before Buying

Before placing a trade, learn about the company. Read its most recent quarterly earnings report, available on the company's investor relations website or through your broker. Look at revenue, profit, and growth trends over the past few years. Check the company's debt level and whether it pays a dividend (a regular cash payment to shareholders).

Review analyst ratings and price targets, but remember that analysts are often wrong and may have conflicts of interest. Look at the stock's price-to-earnings ratio (P/E), which compares the stock price to annual profit per share; a lower P/E may suggest the stock is cheaper, but it could also mean investors expect slower growth. Read recent news articles about the company and its industry.

Use your broker's research tools, which are usually free to account holders. Sites like Yahoo Finance, Google Finance, and MarketWatch offer free stock data, charts, and news. Never invest money you cannot afford to lose, and consider starting with small amounts while you learn how markets work.

Frequently Asked Questions

Can I buy stocks directly from a company without using a broker?

Some companies offer dividend reinvestment plans (DRIPs) or direct stock purchase plans that let you buy shares without a broker, but most investors use a brokerage account for convenience and access to research tools. Direct purchase plans often have higher minimum investments and fewer trading options than brokerages.

What is the difference between a stock and a bond?

A stock represents ownership in a company; a bond represents a loan you make to a company or government. Stockholders profit if the company grows but lose money if it declines. Bondholders receive fixed interest payments and get their money back at maturity, regardless of the company's performance. Bonds are generally less risky but offer lower potential returns.

How much money do I need to start trading stocks?

Most brokerages have no minimum deposit, so you can open an account with as little as $1. However, some brokerages require $500 or $1,000 to access certain features. If you make more than four trades in five business days, the SEC classifies you as a pattern day trader and requires a $25,000 minimum account balance.

What happens if a company I own stock in goes bankrupt?

Your shares become worthless, and you lose your entire investment in that stock. Creditors and bondholders are paid first from the company's remaining assets; stockholders are last in line. This is why diversification matters—one bankruptcy should not wipe out your entire portfolio.

Can I lose more money than I invested in a stock?

If you buy stocks with cash, the most you can lose is what you invested. If you borrow money from your broker to buy stocks (called margin trading), you can lose more than your initial investment because you owe the borrowed amount back regardless of the stock's performance. Most beginners should avoid margin trading.
