Take the time to keep his actions Over time, this is a practice that offers, has many investors, a form of serenity and regular solid performance especially when you adjust your strategy with a minimum of method and setback. I like to decode the scholarship for beginners illustrating with real examples and tools accessible to all. Understanding the dynamics of the market and identifying the real levers to sell allow us to invest without fear and, gradually, gain that confidence that makes the difference, even when emotion is gaining ground.
Never sell your shares: a strategy that makes a difference?
Building on the long term is often successful, according to the stock exchange's teachings and scientific studies: holding shares for several years is the most profitable choice for most individuals. However, it is better to apply this logic with discernment and to remain selective: it is neither an unchanging rule nor an idea received to follow closed eyes! By observing the results and the testimonies, we find that patience ends up paying in near 80% cases... but exposes to certain risks that must be taken into account.
Analyses on Capital.fr and Tikr.com reveal that more 60% days of vigorous rebound follow strong declines, making the "perfect timing" almost inaccessible, even among experienced professionals. Portfolios consisting of quality shares retained 20 to 30 years show a superiority in 90% simulated scenarios for those who go back and forth. There is regular observation among experienced investors: selling is necessary in some specific cases, and this deserves attention on these exceptions.
A "buy and hold" strategy raises many questions – why does the patient approach generally outperform sales? Have you ever feared being trapped when the market dives? This guide offers you an overview, talking numbers and concrete tools to refine your arbitrations in complete peace.
Why keep your actions in the long run?

Before embarking on the "hold forever", it is best to examine what makes this strategy's real strength. It is noted that stock markets reward those who show patience: for example, on 30 years, the S&P 500 index has an annualized performance exceeding 9%, while those who multiply sales usually lack the best sessions.
Imagine: 10 000 € in 1990 in a basket of diversified actions, left "forgotten" and therefore without intervention, would have achieved more than 180 000 € on average 30 years later. Why this result? The compound interest mechanism, amplified by the reinvestment of dividends and the regularity of the increases, works in your favor, while transaction costs and taxation inevitably snack any profit generated by the market timing.
Exceptional days make all the difference
One of the figures intriguing: 85% yields on 20 years are born in less than 20 marked stock exchanges. According to Capital.fr, close to 60% of these days occur within two weeks following marked falls. It is clear that an early sale just after a drop often means missing the expected rebound.
- A return of 7% Year on year 20 years transform 10 000 € in addition to 38 000 €without active intervention.
- Recurring sales can cost up to 2% per year in fees and taxes, significantly impacting overall performance.
- To take off, many institutions only intervene beyond 100 million or 1 billion € This promotes and rewards waiting.
So, is it better to bet on this "snowball effect" or try to overperform by opportunistic sales? According to the opinion of several experts, the second option seems much more uncertain.
Hold, but not everywhere: not all actions are worth
When one holds a solid title, has fundamentals in growth, the logic of waiting becomes clear. But be careful, focusing on small values or investing in declining sectors can put your capital at risk. According to sectoral returns (Euodia.fr, Tikr.com), leaders who have crossed certain capitalisation thresholds outperform the market most generally... provided they maintain a reasonable PER ratio and a real dynamic of activity. As one trainer interviewed during a webinar points out, "nothing is guaranteed in the long term if the company cannot reinvent itself".
Situations where selling becomes a necessity

To insist on "never sell" as a universal principle would lack nuance. Some contexts require action, and it is worth discerning those times when sales protect rather than penalize. A wise investor quickly learns to thwart false loyalty to his securities: sometimes selling is beneficial.
Identify signals that make detention risky
Keeping shares blindly can be expensive when a company:
- Shows signs of weakness over several quarters (decrease in business, rising debt...)
- Facing regulatory disruption or losing a strategic license
- Displays a PER ratio that flashes suddenly (attention: if the PER climbs from 15 to 40 without improving profits, it is often a serious warning)
- Out of a sector dynamic or loses its main competitive advantages
The seasoned investors search their portfolio, use analytical tools and arbitrate in case of a manifest break. Moreover, "never sell" results in: not being dictated by emotion, but responding rationally if the indicators so require. For example, some individuals have avoided significant losses simply by being vigilant about weak signals.
Reallocation, arbitration, new opportunity: selling to strengthen its strategy
When an emerging company has a twofold increase in profitability or growth prospects, it becomes wise to calculate arbitration with the help of a simulator. The options now make it possible to obtain projections of 5 to 20 yearsoften free.
- A wealth balance sheet is generally available upon opening an account or upon request – some providers guarantee a response less than 24h.
- You can contact an advisor directly to validate your decision, mostly by chat or phone.
Sales should never respond to temporary nervousness, but rather to sustained reflection and objective analysis of fundamentals. Moreover, several professionals share that this type of approach prevents many later regrets.
Managing your emotions to invest better
Everyone has already felt this tension in the face of a fall in 20% on a title, hesitated, or feared losing everything. Mastering investor psychology becomes essential. To keep in the long run is also to know how to "disconnect" during turbulences and refuse the trap of sudden stress: some evoke emotional "noise" as their main obstacle.
Cognitive Bias–the real challenge of duration
Research in neurofinance, supported by thousands of individual routes, shows that selling too early often comes from loss bias or fear of the crash. More 70% individuals lose on average 2 to 3% annual performance due to over-emotional reactions.
To get out of this fragile zone, a few markers are required:
- Write down your allocation plan with clear rules (only if fundamentals change, never on a price drop).
- Compare your portfolio with benchmarks: most platforms offer the opportunity to analyze any significant discrepancies in real time and understand their cause.
- Joining a masterclass or a community of investors: sharing experience and human encouragement help overcome times of crisis, as several members found during the last market correction.
If some of these fears seem familiar, be reassured: they are regularly observed and it is possible to learn to control them gradually.
Building resilience: useful tips and methods
A small gesture can make the difference: program a monthly alarm to reread its heritage objectives. It's an idea slipped to Noah (my 11-year-old son), just to prevent him from selling his first stock too quickly after a low day. We can also take advantage of portfolio simulators: see, with supporting figures, the impact of a temporary decrease on the long-term calm result, often instinctive reaction. Some professionals recommend this practice to young investors in order to anchor a long-term vision.
Fit with the right tools to keep your mind quiet
Implementing a "hold" strategy inevitably requires the right instruments. Today, between interactive simulators, offered balance sheets and masterclasses, everyone can equip themselves to choose what suits them.
The simulator: a precious companion
