Thediversificationplays a central role in securing your finances and business: it avoids dependence on a single source of income or investment. Through concrete examples and advice adapted to the different stages, it becomes possible to organise itsdiversification strategywithout increasing the risks, while opening the door to new opportunities – whether you're a starting entrepreneur, parent or investor. (Some professionals sometimes find that the click comes by watching the neighbor who dares to broaden his horizons.)
Definition and basic principles
When it comes to diversification, it is ultimately about expanding its activities, products, markets or investments to avoid relying on a single option. This reflex is as much business prudence as financial management: it is often used to limit the consequences if a sector encounters difficulties or if the situation becomes unstable.
Take the case of a bakery that decides to go into the pastry: if the sale of bread ever decreases, the sale of cakes can take over. In finance, having both shares, bonds and real estate gives the possibility to avoid a single market drop affecting your entire savings. According to some institutional guides, it is better to choose between three and six major supports on a multi-support life insurance – this is a concrete illustration, accessible even to beginners!
Finally, diversifying simply means refusing to depend on one lever and giving yourself a chance to bounce back. But then, do we have to imitate big companies, or do there exist several ways to achieve this?
Major types of diversification
The methods vary by sector, but on the whole several large families of diversification are emerging. A trainer recently mentioned that many project leaders are asking: should we innovate in the current field, or should we buy a complementary activity?
Internal and external diversification
Internal diversification consists of developing new offers, markets or products from within existing resources. For example, an SME decides to invest in the manufacture of electric bicycles after producing only conventional bicycles. This change requires, on a regular basis, between 12 and 24 months before having a real impact on turnover, according to the BDC.
Conversely, external diversification is based on partnerships, buybacks or acquisitions of existing companies and products. This is the quick way, often chosen by major groups: in 2023, just over 40% of the diversification strategies of CAC 40 companies were acquisition-based, according to a sectoral study. For a small business, this can mean large costs and administrative complexity. (Sometimes a manager is surprised by the regulatory burden of a buyback.)
Horizontal, vertical, conglomerate and geographical
Some benchmarks to find in these sometimes blurred notions:
- HorizontalTo expand the supply in its main business, e.g. a new product expanding with fresh juices.
- Vertical: integrate an additional step into the chain of activity – a furniture manufacturer who decides to open his own wood shop.
- Conglomerate: adventure in a field without obvious link (some bakers have for example opened a micro-creche!).
- Geographical: to set up its services in another region or internationally.
On the finance side, diversifying its portfolio consists in allocating its investments to different types of assets: equities, bonds, real estate, raw materials, etc. According to an AMF study, a diversified allocation over 5 to 10 years has reduced annual yield volatility by over30 %in relation to a portfolio composed solely of shares. (Some managers point out that this type of distribution brings a significant serenity in times of turbulence.)
Is it really complicated? Sometimes, starting in a simple way – especially for an SME or a less experienced person – remains the most cost-effective strategy in the medium term.
Why diversify?
To secure your future, go through crises without too much damage, and seize the new window opportunity. Changing course can impress, but remain static, often exposes to more severe risks. (A seasoned entrepreneur recalls that it is often small changes that avoid big falls.)
Reducing dependency and volatility
To bet on a single option is to be exposed to the slightest turbulence. Sometimes it is better to distribute sources of income and smooth variations: diversification is used to compensate for seasonal activity or to cushion economic shocks. During the Covid-19 crisis, companies with two major sources of income observed25% decrease(source: Bpifrance).
For an investor, this choice reduces potential losses and ensures better long-term portfolio stability. To be remembered: diversification never promises maximum yield, but it protects, in concrete terms, against the most difficult scenarios. (Some people note that periods of uncertainty are less stressful with a diversified portfolio.)
Fostering growth and resilience
Sometimes diversification allows access to unsuspecting markets: a textile company also offering zero waste accessories can conquer a new customer base. It is regularly observed that this also serves as a springboard to bounce back during a crisis or to quickly adapt its offers to new regulations.
On the part of individuals, placing their money in different asset classes makes it possible to benefit from various growth engines, without however falling into excessive caution. A reasonable balance remains one of the fundamental keys; Some advisors mentioned that the fatigue of the "all or nothing" disappeared with several options.
Concrete examples of diversification strategies
Field experience sometimes brings more than theory. Recently she accompanied a family-owned SME in the construction sector: to temper the hollow season, she joined a partner and proposed the rental of equipment, in the same territory. Less than18 months, the share of turnover related to this complementary activity reached22 %the annual total. (A store manager admits that it is not uncommon to discover a new carrier segment, by testing simple ideas.)
Sectoral examples and application to investment
Here are some examples to move from theory to practice:
| Situation | Diversification strategy |
|---|---|
| Neighbourhood Bakery | Adds a catering activity to its initial offer (horizontal diversification). |
| Beginner investor | Divides its portfolio between shares, real estate and bond funds (multi-asset). |
| Industrial SMEs | Implements a new production site abroad (geographic + vertical). |
| Farmers | Open a transformation shop to sell in short circuits. |
A benchmark for families: in the area of food, diversification is regularly recommended between4 and 6 monthsin the baby, evidence that the principle applies in many areas, from common sense to investment. (Sometimes a parent discovers the interest of varying proteins during the first purées...)
You're not sure? A "mini audit" of the revenue sources of your business or portfolio can help identify where a second rope to your bow would be relevant.
Limitations and points of vigilance
Diversifying attracts, but this does not exclude certain dangers: it is better not to confuse thoughtful diversification with anarchic dispersion. (A specialist consultant pointed out that the excess of activities regularly harms the whole...)
Dilution risks and increased complexity
A common problem is to scatter. Too many activities without clear strategy can blur your skills, disorient customers or generate hidden costs. The feedback from the field shows that in SMEs, more than half of the60% of failuresdiversification is linked to a lack of prior preparation.
As regards regulation, vigilance remains to be exercised: certain financial products (life insurance, UCITS, ETF) require a minimum level of information on risks, liquidity, and careful selection. It is not uncommon for a multi-support contract to impose a limit ofSix main assetsto avoid the trap of over-diversification. (Some platforms now offer simulators to check the proper balance of allocations.)
It is often recommended to evaluate the consistency between your new projects and your core business. It may also be relevant to take advantage of decision support tools, such as investment simulators or comparative guides available on many specialized portals.
