Investing in a Brokerage Account: How Much Can a CTO Really Earn?

When you invest in the stock market via an ordinary securities account (CTO), one of the first questions is: “how much can it yield?”

The answer depends on three fundamental elements:

1. The assets you hold (stocks, ETFs, bonds, etc.)
2. The associated costs (brokers’ fees, fund fees, etc.)
3. Taxation on capital gains and dividends

Unlike accounts with tax advantages (PEA, life insurance), the CTO offers complete investment freedom, but without the “tax shield” of these other products. In this article, we focus on the expected return, with simple figures, concrete examples, and a realistic view of potential gains from an CTO.

Anatomy of a CTO: what can you put into it? How does this influence the yield of a stock account?

A CTO gives access to a particularly wide investable universe. This variety directly conditions the potential return of the portfolio.

Individual stocks

Stocks are the most rewarding asset class in the long run. On major global equity indices, their historical return ranges from 7% to 10% per year (including dividends). Note, however, that individual stocks can yield very large gains (+ up to 1,175% for Nvidia for example in 5 years) as well as very steep losses (- 99% for Atos for example in 5 years).

Nevertheless, because of their growth potential, stocks represent the main source of growth for a CTO.

ETFs and funds

ETFs allow you to obtain, with a single product, the return of a complete index (equity, fixed income, basket of stocks, etc.). Examples of indices and indicative historical returns:

• MSCI World : ~7–9 %/year
• S&P 500 : ~10 %/year
• Nasdaq 100 : ~12–14 %/year (more volatile)

ETFs are often the preferred option to optimize the risk/return pair.

Bonds, derivatives, etc.

Government or corporate bonds offer lower returns (2–5%/year depending on cycles) but display lower volatility, bringing stability to the portfolio.

Derivatives (options, futures) modify the risk/return profile but are not suitable for everyone. Their leverage can magnify gains… as well as losses. Beware this double-edged tool.

What the CTO enables vs other investment envelopes

Unlike the PEA or life insurance, the CTO allows investment on all global markets. Foreign securities, which are not eligible for the PEA, including the best PEA funds, broaden exposure to more dynamic economies or innovative sectors.

The stock account gives access to potentially higher returns via international markets, but taxes dividends and capital gains immediately, which impacts net yield.

Dividends and capital gains

Dividends provide a steady yield, generally between 1% and 4%/year, higher for certain sectors (listed real estate, utilities). Reinvested, they strongly boost the long-term expected gain.

Capital gains come from the rise in title prices. For diversified indices, the average annual growth sits between 5% and 10%/year depending on markets.

Compound interest: the snowball effect

The compounding effect is decisive for understanding how much a CTO can yield.
Simple example:

• Starting capital: €10,000
• Annual return: 8%
• Duration: 10 years
• Final capital: €21,589, i.e. a rise of +116%

Systematic reinvestment of gains is one of the best levers of performance.

How to measure CTO yield: simple examples

• Global equity portfolio: €10,000 over 15 years at 8%/year → ~€31,700
• Balanced 50/50 portfolio at 5%/year: €10,000 becomes ~€20,800 in 15 years
• Conservative portfolio at 3.5%/year: ~€15,700 in 15 years

These projections show that exposure to stocks is the dominant driver of return.

Stock account: how much does it yield?

We present here realistic magnitudes, based on long-term typical portfolios.

Conservative portfolio (e.g., 60/40 bonds/stocks)

• Expected return: 3% to 5%/year
• Ideal for an investor seeking low volatility
• High share of bonds: more stable return but lower

Balanced portfolio (diversified global stocks/bonds/ETFs)

• Expected return: 5% to 7%/year
• Ideal for an investor seeking the optimal risk/return trade-off
• Good balance of performance and risk

Dynamic portfolio (mostly equities)

• Expected return: 7% to 10%/year
• Ideal for an investor comfortable with risk and with a long investment horizon
• Suited for horizons of 10 years or more

These estimates are based on historical returns and are not a guarantee.

Stock account yield: what is the impact of fees and taxation?

Raw performance is one thing. Net performance in a CTO is another, because fees and taxation directly reduce the expected yield.

Brokerage fees, custody fees, ETF/fund fees

• Brokerage fees erode performance if the investor makes many transactions.
• ETF management fees range from 0.05% to 0.50%, and funds can exceed 2%.
• Custody fees (sometimes €0 depending on the broker) affect net yield.

Flat tax / social contributions

The flat tax of 31.4% includes:

• 12.8% income tax
• 18.6% social contributions

Real impact: a gross gain of €1,000 yields €694 net. The more frequent the sales, the more taxation gnaws at yield.

Stock account: how to optimize the yield of your CTO?

Optimal diversification

Diversification reduces volatility for the same level of return.

Combining global ETFs + sector-specific ETFs + bonds stabilizes the portfolio.

ETF vs individual stocks

• ETFs improve net yield thanks to ultra-low fees.
• Individual stocks can outperform, but increase idiosyncratic risk.

Passive vs active management

Studies show that passive management outperforms active management in most cases. This is largely due to lower fees, less turnover, and thus better optimization of net yield.

Arbitrage and rebalancing

Periodic rebalancing (selling what has risen, reinforcing what has fallen) helps optimize the return/risk pair over the long term.

Café de la Bourse verdict: how much does a CTO really yield?

Practical summary

• Conservative : 3–5 %/year
• Balanced : 5–7 %/year
• Dynamic : 7–10 %/year

After taxation and fees, net yields are generally 2 to 3 percentage points lower.

Stock account vs other investments: a comparison

• Livrets: 2–4% gross / net often <3%
• Life insurance euro funds: 2–3.5%
• Diversified CTO in equities → 5–7% net long term

Should you invest with a stock account? Decision checklist

• Long-term horizon (8+ years)?
• Investments in world equities?
• Acceptance of volatility?
• Plan for regular contributions with fractional shares?

If yes, the CTO can be the right investment. If, on the other hand, you primarily want to invest in ETFs and implement a dividend strategy, the PEA would be more relevant.
