An investment in the stock market is based on the purchase of financial securities (stocks, bonds, fund shares) with the aim of growing capital over a defined period. Savings, on the other hand, refers to the placement of sums in regulated or contractual supports, often with guaranteed capital. Combining the two requires understanding what each mechanism produces and what it actually costs.
ETFs and PEA: What the wave of new investors changes in 2026
The AMF published a report on September 23, 2026, marking a turning point. Nearly 900,000 individuals bought or sold ETFs during each of the first two quarters of 2026, representing a 39% increase compared to the second half of 2025. The number of new ETF investors reached its highest level since 2018.
This acceleration does not mean that all these investors master the product they are buying. An ETF replicates a stock index (CAC 40, S&P 500, MSCI World), but the replication method changes the risk profile. A physical replication ETF directly holds the stocks of the index. A synthetic replication ETF uses a swap contract with a banking counterparty to replicate performance without owning the underlying securities.
International synthetic ETFs remain eligible for the PEA. On August 26, 2026, the Minister of Public Accounts confirmed that the government would not propose to exclude them. This decision is reassuring, but the framework remains politically uncertain, as the subject has already been debated several times.

Portfolio allocation between stocks, secure savings, and life insurance
Placing the entirety of capital in stocks exposes one to volatility that most savers underestimate until they have experienced it. The allocation between asset classes is the main lever for risk management, much more than the choice of an individual security.
Three pillars to articulate according to the horizon
- Emergency savings (regulated savings accounts, term accounts): guaranteed capital, immediate or short-term liquidity. This base covers unforeseen events and avoids selling stocks during downturns to finance an urgent expense.
- Stocks and ETFs via a PEA or a securities account: long-term performance driver. The recommended horizon generally exceeds five years, as markets go through sometimes prolonged downturn cycles.
- Life insurance in euro funds and unit-linked accounts: a tax-efficient wrapper that combines a secure compartment (euro funds, capital guaranteed by the insurer) and a compartment invested in the markets. It also serves wealth transmission thanks to its specific inheritance regime.
The weight of each pillar depends on the ability to withstand a temporary loss. An investor who will need their capital in two years does not have the same allocation as a saver preparing for retirement in twenty years.
Fees and taxation: the costs that erode real performance
Comparing two investments without including fees is like comparing two gross salaries in two different countries. The management fees of an ETF range from a few hundredths to a few tenths of a percent per year. Those of an actively managed fund are often several times higher, without any guarantee of outperformance.
The PEA exempts capital gains from income tax after five years of holding (excluding social contributions). The ordinary securities account, on the other hand, subjects each gain to a flat tax. Life insurance benefits from a tax allowance after eight years on withdrawals.
A point rarely quantified by savers: the trading fees and custody fees charged by some traditional brokers. On a modest portfolio, these recurring charges can absorb a significant portion of the annual return. Checking the fee schedule before opening an account avoids surprises at the end of the year.
Behavioral biases and social media: the risk that markets do not measure
The AMF has been warning for several years about the growing influence of social media on investment decisions. Short, often oversimplified content presents stock market strategies as accessible and almost infallible. The problem is not the information itself, but the lack of context regarding the risk of capital loss.
The AMF has also initiated work to make pre-contractual documents more readable. The regulator notes that key information documents (KIDs), intended to allow comparisons between products, remain too technical for the majority of savers. An unreadable KID protects no one.
Two concrete reflexes limit the impact of biases:
- Do not invest an amount whose partial loss would prevent covering current expenses for several months.
- Automate periodic contributions to a broad ETF rather than trying to choose the right entry moment. Smoothing the purchase price reduces the weight of short-term fluctuations.
- Systematically check if an online recommended product has AMF approval and an accessible KID before any commitment.
Facilitated access to financial markets is an advancement. The risk lies in the confusion between ease of access and simplicity of the product. A synthetic ETF eligible for the PEA remains an instrument that carries counterparty risk, even if the subscription interface takes three clicks. Keeping this distinction in mind protects better than generic advice on diversification.
