Learn Investing in a Minute: Core Investment Skill - Position Management (10 Fundamental Concepts)

Position Management

A core skill in investing. It's a science and also an art. The essence of investing is not about being right every time, but about making more when you're right and losing less when you're wrong.

The size of your position directly affects your investment psychology. When heavily invested, even minor fluctuations can make you nervous; while with a light position, you can remain calm even during significant market volatility. Managing emotions through position sizing can help avoid poor decisions driven by panic or greed.

According to the "China Investor Behavior Report," over 65% of losing investors have issues with improper position management.

Empty Position, Light Position, Half Position, Heavy Position, Full Position

The proportion of funds invested in assets like stocks or funds relative to the total investment amount.

No holdings is an empty position. Below 30% is a light position. 30% to 50% is a half position. Above 50% is a heavy position. 100% in stocks is a full position.

Empty Position

The investor is in a wait-and-see state. When the market is at a high level with excessive valuations, choosing an empty position can avoid significant losses during a market correction. One should hold an empty position when facing stocks whose prices have already run up excessively.

Light Position

Less than 30%, with more remaining funds and a higher proportion of cash. It's suitable when the market is unstable and the investor cannot confidently predict its direction, representing a conservative approach. A light position helps maintain a steady investor mindset. Because losses are relatively small, they don't impose excessive psychological pressure, allowing for more rational decision-making.

Full Position

All funds are invested in the stock market, reaching the maximum holding. Blindly going all-in is inadvisable; novices often impulsively enter with a heavy position, only to suffer heavy losses from a slight market pullback.

Which stocks can be bought with a full position?

First, the stock hasn't risen in recent years or has seen little increase,

Second, the stock price has undergone a long-term decline and sufficient consolidation. Buy in batches based on the position of the pattern formation until all funds are used.

Opening a Position, Adding to a Position, Averaging Down, Reducing a Position, Closing Out a Position

Opening a Position in Batches

Open a position in batches; don't invest all funds at once. You can buy in 3-5 batches at different price points to diversify risk. The lower the price, the larger the proportion of the addition (pyramid averaging), which helps lower the average cost.

Opening a position all at once, going all-in, is not advisable.

Adding to a Position

Continuing to buy on top of an existing holding, increasing the position size. This is done when optimistic about the prospects of a particular stock or fund, hoping to amplify gains. Timing is crucial when adding; avoid buying large amounts at price peaks. Seeing a rise, you think it can go higher, and you buy more—this is adding to a position. Seeing a drop, you think it's an opportunity, buying more to lower the average cost—this is called averaging down.

Reducing a Position

Selling a portion of the holdings. When market volatility increases your perceived risk, you can lock in profits (take money off the table) or control losses by reducing your position. If you feel the risk is too high or need cash, selling a portion is called reducing a position.

Higher returns come with higher risk; consider reducing your position in batches. For example, one of my funds achieved a 20% return in less than a month. Failing to reduce the position in time, it immediately faced a sharp decline, wiping out more than half the profits.

Closing Out a Position

Selling all holdings. This typically happens when you judge the market trend has reversed or when you need cash urgently. Closing out is a complete exit strategy requiring decisive courage.

Margin Call Triggered

Losing all invested capital, possibly even owing money. The most terrifying scenario. Exercise extreme caution.

Take Profit, Stop Loss

Making a profit, selling a portion to secure gains—this is taking profit.

Losing money, reaching your preset psychological loss threshold, decisively cutting losses and selling to prevent further losses—this is a stop loss. Stop-loss actions are counterintuitive but can preserve some principal.

I am currently mostly in a light position, with no stop-loss point set (even though the maximum loss reached 20%), only a take-profit point (expected return 5%~10%, must not be too greedy).

Chasing Rises and Selling Drops

Chasing a rise means watching a fund or stock keep rising, unable to resist following the trend and buying, often buying at the peak.

Selling on a drop means panic-selling during a sharp decline, selling regardless to avoid further losses, often selling at the bottom. Buying high and selling low—a classic money-losing move. Exercise extreme caution.
