Owning 100 shares, often called a "round lot," is primarily required to efficiently trade options, specifically to sell "covered calls" for income. It represents the standard contract size for options, allowing you to use shares as collateral to hedge positions or generate premiums. Additionally, it simplifies ownership tracking.
Each contract represents 100 shares of the underlying stock. Investors don't have to own the underlying stock to buy or sell a put. A reminder: Just like call options, put options are considered derivatives because their value is derived from another security (e.g., stock, bonds, index or currency).
An investor buys shares of stock in a company. The stock represents the company, and is sold in units called shares. Thus, an investor can own a certain number of shares of a company's stock: e.g., they might own 100 shares of Company A. But it's incorrect to say an investor owns 100 stocks in Company A.
A standard option controls 100 shares of the underlying stock or ETF. Therefore, you must have enough buying power to purchase 100 shares for each contract you exercise. Although you have the right to exercise your option, it may not always make sense to do so.
A covered call is a basic options strategy that involves selling a call option (or “going short,” as the pros call it) for every 100 shares of the underlying stock that you own. It's a relatively simple options trade to set up, and it generates some income from a stock position.
If the call is ITM—below the stock's current price—on or before expiration, the likelihood that the option buyer will exercise their right to buy the underlying at the strike price increases. If this happens, the covered call seller is required to deliver the stock—100 shares for each options contract sold.
The 3-5-7 rule in trading is a risk management guideline: risk no more than 3% of capital on one trade, keep total risk across all trades under 5%, and aim for winning trades to be at least 7% larger than losing trades (or a 7:1 ratio) to ensure profits outweigh losses and protect capital. It promotes discipline, reduces emotional trading, and balances potential high rewards with controlled risk, making it great for beginners.
Stocks are most commonly sold in round lots, or lots of 100 shares or more. A lot of less than 100 shares is called an odd lot; odd lot transactions generally have greater commission costs associated with them. Financial professionals advise having enough money to buy a round lot of shares in one company.
A high-yield savings account is a risk-free way to grow your investment. Some of the best high-yield savings accounts offer interest rates as high as 5%. The catch is that it can take time for wealth to accumulate. If you deposit only $100 in an account with 5% interest, it will take 47 years to reach $1,000.
The 7% sell rule is a stock trading guideline to cut losses quickly, advising you to sell a stock if it drops 7-8% below your purchase price to protect capital, remove emotion, and prevent small losses from becoming catastrophic, a strategy popularized by William O'Neil's CAN SLIM method for growth investing. It assumes that truly strong stocks typically don't fall much below their buy point, so a dip signals something is wrong, requiring you to exit the trade to preserve funds for better opportunities.
Round lot. A round lot (or board lot) is a normal unit of trading of a security, which is usually 100 shares of stock in US. Each stock exchange has its own regulations regarding round lot sizes: they can range anywhere from 1-100 shares, depending on the exchange.
You don't need thousands of dollars or decades of experience. With just $100, you can take your first step into the market. And that first step is far more important than waiting until you have more to invest.
You make money on a put option primarily by profiting from a decrease in the underlying stock's price, either by buying puts (betting the stock falls) and selling them for more or exercising to sell high, or by selling (writing) puts (betting the stock stays flat/rises) and keeping the premium if the stock stays above the strike price. Profits come from the difference between the strike price and market price (minus premium) for buyers, or by collecting the premium for sellers when the option expires worthless.
The "24-year-old trader making $8 million" refers primarily to Jack Kellogg, a successful day trader who reported over $8 million in gains from trading in 2020 and 2021, starting with just $7,500 and leveraging key indicators like VWAP, support/resistance, volume, and linear regression for simple, adaptable strategies. His story highlights achieving significant returns by weathering different market conditions, learning from losses, and sticking to core principles rather than overcomplicating things.
The "7-3-2 Rule" refers to two main concepts: a financial strategy for wealth building, suggesting it takes 7 years for the first major savings milestone, 3 years for the next, and 2 years for the third, driven by compounding and increasing investments; and a trucking rule (7/3 split) allowing drivers to split their 10-hour mandatory break into 7 hours in the sleeper berth and 3 hours of off-duty rest, offering flexibility.
