Successful share trading is not a promise of profit: it means making informed choices, controlling avoidable costs and understanding the risks you take. These 10 practical tips can help you approach buying and selling company shares more deliberately. The guidance cited here is from U.S. SEC and Investor.gov materials; readers elsewhere should check their local regulator, tax rules and broker terms.
1. Set a goal and time horizon
Be clear about why you are buying or selling a share and when you may need the money. A decision that suits a long-term goal may not suit money you expect to use soon. Your time horizon helps shape how much volatility and potential loss you can tolerate.
2. Match decisions to your risk tolerance
Consider how you would respond if a share fell in value, and whether you could afford to lose the money invested. All investments carry risk; you can lose some or all of your money. In general, higher potential returns come with greater risk, not certainty of a better outcome. Investor.gov explains investment risks.
3. Research the company and what can affect its share price
Before trading, learn what the company does and consider the factors that could affect its business and the value of its shares. Know why you are buying or selling rather than acting on a headline, tip or sudden price move alone. Investor.gov’s Online Investing guidance puts it plainly: “Online trading is quick and easy, but online investing takes time.”

4. Diversify where it fits your plan
Putting all your money into one company exposes your portfolio to that holding’s fortunes. Diversification means spreading money among investments with different risk and return characteristics; it may lower overall portfolio risk, but it cannot guarantee against losses. Whether and how to diversify depends on your circumstances and investment plan. See Investor.gov’s introduction to investing and its overview of investment products.
5. Accept that a trade can lose money
A share can fall, and an investment may be worth less when you sell than when you bought it. Do not treat a hoped-for gain as guaranteed or trade money you cannot afford to lose. A sound process can help you make informed decisions; it cannot remove market risk or ensure profit.
6. Check the full cost of the account and trades
Fees reduce the money in a portfolio that remains available to earn returns. Brokerage firms’ charges vary, so read the fee schedule and account terms rather than comparing accounts on a single headline commission. Check for:
- Transaction charges or commissions, plus markups or markdowns where relevant.
- Platform, maintenance, inactivity or minimum-balance fees.
- Transfer or account-closing charges.
- Account features and policies that may affect how you trade.
The SEC’s fee bulletin, dated July 23, 2025, explains how fees affect a portfolio. Its hypothetical illustration assumes a $100,000 starting investment, 4% annual growth and 20 years; it is not a forecast of investment performance. Investor.gov’s brokerage account guide also outlines account considerations.
7. Consider liquidity before trading
Liquidity affects how readily you may be able to buy or sell a share. Think about whether you can enter or exit a position when you intend to, and how much uncertainty you can accept about the price. A desire to trade quickly does not mean a particular order will fill at your preferred price.
8. Choose an order type by its trade-off
Order types differ in how they balance the chance of execution against control over price. A market order generally seeks execution, but the execution price is not guaranteed. A limit order sets a price boundary, but it may not execute. Stop orders trigger into market orders; stop-limit orders add a limit condition and therefore may remain unfilled.
| Order type | What it prioritizes or sets | Main trade-off |
|---|---|---|
| Market | Seeks execution at the best available price when the order reaches the market. | Execution price is not guaranteed. |
| Limit | Sets the price boundary at which you are willing to buy or sell. | The order may not execute. |
| Stop | When triggered, becomes a market order. | Execution price is not guaranteed after triggering. |
| Stop-limit | When triggered, becomes a limit order. | The limit condition can leave the order unfilled. |
Availability and trigger policies can differ by firm and venue. Check your broker’s explanations before placing an order. The SEC’s Understanding Order Types bulletin was originally dated July 12, 2017; search results report an update on August 18, 2026. Investor.gov also describes types of orders.

Where and how an order is executed can affect transaction cost and the price you receive. Broker practices and policies matter, so understand how your firm handles orders and what order instructions it offers. After placing an order, check whether it executed; if you request a cancellation, confirm that it was canceled before placing another order. A cancellation request is not the same as a confirmed cancellation. See Investor.gov’s guidance on executing an order and online investing.

Do not let urgency or an unverified claim substitute for research. Be cautious of investment pitches built around pressure to act quickly or promises that a trade is certain to pay off. Verify claims and the identity of the people or firms involved, and consult your local regulator’s resources and warnings. The SEC and Investor.gov guidance cited above is U.S.-focused; account protections, rules and remedies differ by jurisdiction.
