Who are the people standing on the floor of the NYSE?

Today, not all of the trading is done on the floor of the New York Stock Exchange itself (computers help now), so it isn’t as chaotic as it once was. However, the NYSE is one of the few remaining trading floors where much active trading still happens in person.

As technology evolved, so did Wall Street

Electronic trading transformed investing, ushering in a new era for retail investors in which average Americans could research stocks online and then use early platforms like StreetSmart and E-Trade to conduct their transactions

Retail investors can get exposure to commodities via various financial vehicles

While retail investors likely won't go out and purchase a bushel of commodity wheat to trade, they can get exposure to the commodities market via commodity ETFs sold on traditional stock exchanges like the NYSE and Nasdaq and other financial vehicles. There are benefits to adding commodities to a retail investor portfolio (such as a hedge against inflation and a typically low correlation with more traditional asset prices), experts caution that commodities are usually volatile investments.

There's a grading room on the eighth floor of the New York Stock Exchange where experts loudly slurp coffee and then spit it out to test its quality

Insider trading is the practice of trading a company's securities based on material, nonpublic information

"Material, nonpublic" information is essentially any undisclosed information that could have a substantial impact on an investor's decision to trade a security. While the practice is strictly prohibited on the stock market, it's now being discussed regarding less-regulated but increasingly popular prediction markets.

Investors need a 'margin account' to short sell stock

Margin accounts are leveraged accounts through brokerage firms that allow investors to make trades without the full amount of capital on hand. Similar to a secured loan, margin accounts often require some form of collateral and typically have a cap on how much investors can borrow. However, trading with a margin account is much riskier than a traditional investment account. Fees and charged interest are due on margin accounts, regardless of trade performance, meaning it's possible for investors to lose more money than just their initial investment.

While stock options give investors the right to do these trades, they do not obligate buyers to follow through with them—sellers, on the other hand, must perform the option if it is exercised

In its early years, HBO didn't air 24/7
