You cannot remove these risks, but you can decide how much of each you accept. In Malaysia, you also pay trading costs such as brokerage, clearing fees and stamp duty on each transaction, and these reduce returns, particularly for frequent trading. Check your broker’s current schedule.

Step 2: Set a maximum loss per idea. Decide what share of your investment capital you are willing to lose on any one position. Many educators suggest keeping it to a small single-digit percentage, but the right figure depends on you.

Step 3: Size the position from the loss, not the hope. Work backwards. The amount you are prepared to lose, divided by the loss per share if your exit is triggered, gives the number of shares. Round down to Bursa’s standard board lot of 100 units.

Step 4: Write the exit before the entry. Decide the price or condition at which you will accept that the idea is wrong. This might be a level based on chart structure, such as below a volume support zone, or a fundamental reason, such as a failed earnings expectation.

Step 5: Diversify sensibly. Spread positions across sectors that respond to different drivers. Avoid holding many stocks that are effectively the same bet, such as several glove makers or several banks.

Step 6: Check liquidity. Before buying, look at average daily turnover. If your intended position would be a large part of it, exiting could be difficult.

Step 7: Keep a cash buffer. Cash lets you act on opportunities and avoids forced selling when markets fall.

Step 8: Review regularly. Revisit each position after every quarterly report and at least once a quarter in your total portfolio.

Step 9: Keep a diary. Record why you bought, what you felt, and what you learned. Patterns in your behaviour are often a bigger risk than patterns in the market.

The investor is considering a hypothetical Company A at RM2.00 per share. The chart shows a heavy volume support zone at RM1.85, and the investor decides that a close below RM1.85 means the idea has failed. The loss per share if the exit is triggered is RM0.15.

The position is sizable at 26.4% of capital, even though the loss is limited to about 2%. A cautious investor may feel that a single stock at over a quarter of the portfolio is too much concentration, and could decide to cap any position at, say, 15% of capital. At RM7,500, the investor would buy 3,700 shares and the loss at exit would be about RM555. This shows that risk management has two layers: a limit on the loss per idea, and a limit on the size of any single holding.

Also note what the table ignores. If the stock gaps down overnight to RM1.75, the actual loss is larger than planned. Brokerage and stamp duty add to cost. The plan shrinks the risk, but it does not remove it.

• Emergency fund and short-term needs kept outside the market.
• Maximum loss per idea defined in ringgit.
• Position size calculated from that loss.
• Exit condition written before entry.
• Cap on single-stock and single-sector exposure.
• Liquidity checked against intended position size.
• Costs considered, including brokerage and stamp duty.
• Cash buffer maintained.
• Diary entry made for each decision.
• Review scheduled after each quarterly report.

• Averaging down without a reason. Adding to a falling stock because the price is lower is not analysis.
• Moving the exit. Lowering your stop when price approaches it defeats the purpose.
• Confusing diversification with owning many stocks. Look at how holdings behave together.
• Using borrowed money without a plan. Margin can magnify losses beyond your capital.
• Ignoring gaps and suspensions. Bursa can suspend trading, and prices can open far from the previous close.
• Skipping the diary. Without it, you repeat the same emotional mistakes.
• Believing a good company is always a good entry. A good stock is not always a good entry.
