Smart Trading | Buying makes you an apprentice; selling makes you a master! Essential short-term and long-term exit strategies for beginners

"The stock is up 10%; should I sell half now? But if it rises further after I sell, wouldn't that be a huge missed opportunity?"

"It's already down 25%. As long as I don't sell, it's not a real loss... I'll just wait for it to break even."

If you've only been in the market for a year or two, these two mindsets should sound familiar.

Many novice investors spend extensive time researching "which stock to buy," "when to buy," and "at what price to enter," yet rarely ask themselves one question before pulling the trigger:

"How will I exit if things don't go as planned? And if I make a profit, when should I take profits?"

In reality, buying is just the beginning; selling is where investment discipline is truly tested.

Why is selling stocks harder than buying them?

Buying stocks might rely on conviction, narratives, recommendations from friends, or even impulse.

But selling stocks involves navigating more complex human psychology:

– When in profit, fear of selling too early and missing out on further upside;

– When at a loss, reluctance to admit mistakes, clinging to the hope that "it will eventually break even";

- It keeps rising, and greed makes you want to hold on for more;

- It keeps falling, yet you console yourself with 'long-term investment.'

More importantly, the logic behind selling varies significantly across different investment strategies.

If you apply short-term trading stop-loss rules to a high-quality long-term stock, you might be shaken out by normal volatility. Conversely, if you adopt a long-term value investing mindset and stubbornly hold a momentum stock intended only for a quick trade, you risk turning a 'short-term flip' into being 'stuck in a losing position for the long haul.'

Therefore, before selling a stock, the first step is not to look at charts, but to recall your original reason for buying.

Ask yourself first: What was my initial reason for buying?

Please categorize your investments into two main types.

1. Long-term Value / Fundamental-based

You buy because you believe in the company's long-term value, such as:

- Stable profitability;

- Clear industry outlook;

- Reliable management team;

- Healthy cash flow;

- Possesses a competitive moat;

- Attractive dividend policy;

- Relatively reasonable valuation.

In short, you are buying the "company" itself.

2. Short-term Momentum / Trend Trading Style

You buy because the stock price is forming a strong trend, for example:

- Breaking through resistance levels;

- Supported by trading volume;

- Strong demand from market capital;

- Technical patterns are strengthening;

- The sector has short-term catalysts.

Simply put, you are trading the "price trend."

Long-term value investors: Focus on the company, not daily stock price fluctuations.

If you are a long-term investor, you should not sell stocks solely due to price pullbacks, nor should you panic over short-term news volatility.

The real questions long-term investors should ask are:

"Has the company's fundamentals deteriorated? Is the valuation already too expensive? Are there better uses for the capital?"

1. The original investment thesis has changed.

If you bought a stock due to its stable earnings, high growth, strong brand, or industry advantages, you should reassess whether it is still worth holding when these conditions disappear.

For example:

- Declining competitiveness of core products;

- Continuous deterioration in earnings;

- Persistent decline in gross profit margins;

- Sharp increase in debt;

- Industry being displaced by new technologies;

- Issues with management integrity or corporate governance;

- The original high-growth narrative no longer holds true.

Example: Berkshire Hathaway completely liquidated its stakes in the four major U.S. airlines in April 2020. Buffett admitted he "made a mistake," pointing out that the pandemic fundamentally changed the airline industry, rendering it inconsistent with the original investment thesis.

However, be cautious when analyzing fundamentals; do not mistake seasonal fluctuations for a deterioration in company performance. Industries such as retail and tourism naturally have peak and off-peak seasons. When comparing revenue or earnings, focus more on year-over-year comparisons, quarterly trends, and management guidance, rather than looking at a single quarter in isolation.

2. Valuations are overheated; consider taking profits in tranches.

A good company does not mean it is worth holding at any price.

When market sentiment is extremely euphoric, and stock prices rise far above reasonable valuations—even pricing in growth for the next few years—long-term investors may consider reducing their positions in tranches.

The benefit of this approach is that you don't need to guess the absolute peak, nor will you miss out on subsequent gains by selling your entire position at once.

3. Selling is also a reasonable choice when better opportunities arise.

Selling does not necessarily mean you are bearish on a stock.

Sometimes, it is simply because better options have emerged in the market.

For example, if you hold a company with slowing growth and an expensive valuation, while another company with stronger finances, more attractive valuation, and higher risk-adjusted returns appears in the market, switching positions may be a reasonable asset allocation decision given limited capital.

Investing is not about collecting stocks, but about managing capital. Investors must consider their investment horizon and risk tolerance, as exceeding their capacity to withstand volatility may lead to selling at inopportune times.

Example: Berkshire Hathaway has been reducing its Apple stake in tranches over the past few years. At the shareholders' meeting, Buffett clarified that Apple remains an exceptional company. The primary reasons for the reduction were to lock in profits ahead of potential future increases in U.S. corporate capital gains tax rates, manage the risk of an overly concentrated position, and optimize overall cash allocation.

Short-term momentum traders: Focus on price; discipline is more important than insight.

If you are buying momentum stocks, thematic stocks, or breakout stocks, or if you only intend to trade short-term, do not use "long-term investment" as an excuse for yourself.

The most important aspect of short-term trading is not being right every time, but losing less when you are wrong and earning more when you are right.

1. Set your stop-loss level before buying.

The biggest taboo in short-term trading is "calculating after buying."

Before buying, you should write down three things:

– What is the reason for buying?

– If the judgment is wrong, at what price should you exit?

– If it rises, how will you take profits in batches?

A common practice is to set a tolerable stop-loss range, such as -7% to -10%. However, this is not an ironclad rule; the actual range should depend on the stock's volatility, position size, market conditions, and individual risk tolerance.

Using stop-losses isn't an admission of poor judgment; it's an acknowledgment that the market always carries uncertainty.

2. Use trailing take-profits and let go of the desire to sell at the absolute peak.

The biggest challenge with short-term momentum stocks is that they rise quickly but also fall just as fast.

If you sell too early, you might miss a major rally; if you get too greedy, you risk giving back all your profits.

A more practical approach is to combine "scaling out" with "trailing take-profits."

For example:

– When the stock price rises 15% to 20% above your entry price, sell a portion to recover your capital or lock in some profits;

– Manage the remaining position with a trailing take-profit, such as reducing your position or exiting entirely if the price pulls back 5% to 8% from its high;

The core of this strategy isn't about selling at the highest point, but rather allowing you to hold while the trend remains intact and providing a mechanism to exit when the trend weakens.

3. Respect market signals when key technical levels are broken.

Short-term trading focuses on price action. If a stock breaks below key support, it suggests that the market's short-term outlook for that stock may have changed.

Common warning signs include:

– Falling below the 20-day or 50-day moving average;

– Breaking below the bottom of the previous consolidation range;

– Declining on heavy volume;

– A sharp pullback following a failed breakout;

– Broad weakness in the sector;

– Rising market-wide risk.

Technical levels are not crystal balls, but they help you maintain discipline and prevent small losses from turning into large ones.

Make good use of order tools, but don't rely on them blindly.

NiuNiu offers various types of orders. For beginners, knowing how to use these tools can help reduce emotional trading.

1. Limit Order: Controls the minimum selling price, but execution is not guaranteed.

A limit order allows you to sell at a specified price or better. The advantage is that you can control the minimum acceptable selling price; the downside is that if the market price does not reach your limit, the order may go entirely unexecuted or only partially filled.

2. Market Order: Easy to execute, but the price may not be ideal.

A market order does not require specifying a price and executes at the current market price, making it easy to fill. However, during sharp price drops, widened bid-ask spreads, or low liquidity, the execution price may be worse than expected.

3. Stop-Loss Order: Helps you control losses.

A stop-loss order automatically triggers a sell instruction when the stock price falls to a preset level, helping investors control losses and preventing small losses from turning into large ones due to hesitation, reluctance, or wishful thinking.

Common types of stop-loss orders include: Stop-Market Orders and Stop-Limit Orders.

A Stop-Market Order prioritizes execution; once the stock price hits the trigger price, the system will sell at the market price as quickly as possible (with no guarantee on the execution price). A Stop-Limit Order, upon triggering, will sell at the specified limit price or better, prioritizing the execution price.

4. Touch Order (Take-Profit): Helps you lock in profits.

A touch order automatically triggers a sell instruction when the stock price rises to the target level, helping investors lock in profits and avoid missing out on gain opportunities due to greed or hesitation.

Common trigger orders include: Trigger Market Orders and Trigger Limit Orders.

Trigger Market Orders prioritize execution; once the stock price reaches the target price, the system will sell at the market price as quickly as possible (execution price is not guaranteed). Trigger Limit Orders, on the other hand, will sell at the specified limit price or better after being triggered, prioritizing the execution price.

5. Trailing Orders: Help you let your profits keep rolling

Trailing orders allow users to set a trailing amount or trailing percentage, defining a specific price spread. The system automatically calculates the stop-loss trigger price based on market price movements. As the stock price rises, the trigger price moves up with the highs; when the stock price falls from its high by the preset amount, the system triggers a sell order, helping investors protect their existing profits.

Common trailing orders include: Trailing Stop Market Orders and Trailing Stop Limit Orders.

Trailing Stop Market Orders prioritize execution, suitable for those who want to exit quickly when an uptrend weakens; Trailing Stop Limit Orders will execute as a limit order after being triggered, prioritizing the execution price.

Must-do before selling: 3 seconds of perspective-taking

When facing stocks that are trapped in losses and you're unsure whether to sell, ask yourself this highly effective question:

If I held cash instead of this stock today, would I still be willing to buy it at the current price?

If the answer is "Yes," you must be able to state your reasons:

– Fundamentals remain healthy;

– Valuation remains reasonable;

– Long-term returns remain attractive;

– Technical trends remain intact;

– The rationale for holding still holds.

If the answer is "no," you need to be honest with yourself: your decision to continue holding may simply stem from unwillingness to accept loss, fear of admitting defeat, or the influence of sunk costs.

Not selling does not mean there is no loss. Although paper losses are unrealized, your capital is already tied up, meaning you have missed out on other investment opportunities.

Do not ignore your investment records

Keeping detailed trading records is essential to know whether you are truly making or losing money. Therefore, it is recommended to record every transaction:

– Purchase date;

- Entry price;

- Exit date;

- Exit price;

- Transaction costs;

- Rationale for entry;

- Rationale for exit;

- Final outcome;

- Post-trade review.

Remember not to try to pick the top; instead, exit with discipline.

A truly mature investor doesn't buy at the absolute bottom and sell at the absolute high every time, but rather knows before each entry:

- Why buy;

- Under what conditions to hold;

- Under what conditions to reduce position;

- Under what conditions to exit completely.

For long-term investing, focus on the company; for short-term trading, focus on the price. The biggest mistake is entering a trade with a short-term mindset, then pretending it’s a long-term investment after the price drops.

Remember, selling is not a failure but part of capital management. You truly evolve from knowing how to buy to knowing how to sell only when you replace emotions with clear rules and luck with discipline.
