Forex or the stock market — what to choose in 2026

Picture two identical sums from 2010, each of 5,000 zloty. The first goes into an ETF tracking the S&P 500 index. The second lands on a CFD account with a forex broker and starts trading EUR/USD with leverage. Fourteen years later the first portfolio, after reinvested dividends, is worth roughly 22,000 zloty. The second, in seven cases out of ten according to ESMA statistics, sits at zero or below the initial deposit. In this article I compare both paths along trading hours, leverage, long-term returns, dividends and regulation, to help you choose the right one for a European retail profile.

The stock market from a European perspective

A European retail investor has two parallel worlds to choose between. The first is the local exchange — in Poland the Warsaw Stock Exchange (GPW), with index families WIG, WIG20, mWIG40 and sWIG80. The GPW session runs from 09:00 to 17:05 Central European Time with a closing fixing. The second is foreign exchanges — NYSE and NASDAQ in the United States, Frankfurt, Paris and London — reached through a local broker (XTB, mBank Maklerski, BOSSA) or the European arm of a global one (Interactive Brokers via its Irish entity, DEGIRO).

On the stock market you trade actual ownership in a company. You hold a security, with rights to dividends, to participate in buybacks and to vote at a shareholder meeting on larger stakes. Apple paid out roughly one dollar per share in dividends in 2024 and added more than twenty billion dollars in buybacks. Microsoft, Coca-Cola, Procter & Gamble — all have distributed dividends regularly for decades. This is cash flow that lands on your account regardless of price movement. Leverage on EU equity CFDs is capped by ESMA at 1:5, and in practice most European investors never use it at all — they buy shares for the full price and hold them for years.

Forex and CFDs

The foreign exchange market is a global currency market that runs in an over-the-counter model — no central exchange, only banks and brokers exchanging liquidity through an electronic network. For European retail access happens through CFD brokers (Contract for Difference). When you buy EUR/USD with a broker such as XTB, you do not receive euros — you open a contract whose settlement depends on the move of the underlying rate between opening and closing. The mechanics of this OTC market are covered in detail in the introduction to forex basics at ForexMechanics. The underlying difference between owning an asset and holding a price-difference contract is examined in the piece on ETF versus CFD and forex — ownership versus a contract.

The market runs twenty four hours a day, five days a week — from the Monday Sydney open to the Friday New York close around 22:00 Central European Time. This is the fundamental difference compared to the stock market. You can trade EUR/USD at three in the morning, open a position on Sunday evening for the Asian session, close the last trade of the week on Friday afternoon.

Leverage on forex majors under ESMA rules is capped at 1:30 for retail — six times the leverage available on EU equity CFDs. This very leverage is the reason ESMA forces brokers to display a warning: between 74 and 89 percent of retail accounts lose money on CFDs over a single quarter. Forex pays no dividends and no buybacks — cash flow is zero until you yourself close a position. A full breakdown of why retail loses on leveraged CFDs is in the chapter on risk management.

Comparison along the key dimensions

The most important row of this table is the one on the probability of profit. Buy and hold on a broad equity index over many years statistically beats the overwhelming majority of active strategies — this conclusion is repeated by Burton Malkiel, John Bogle and every serious portfolio strategist over the last forty years. Active CFD trading over the same period has, in retail, the opposite distribution: the clear majority loses. This does not mean active trading cannot be profitable — it means it has to be treated as a trade in itself, not as a lottery ticket.

"The best way to own common stocks is through an index fund that charges minimal fees. Those following this path are sure to beat the net results delivered by the great majority of investment professionals." — Warren Buffett, Berkshire Hathaway shareholder letter, 2014.

When to choose stocks and ETFs

Stocks and ETFs are the default choice for most European retail investors. The S&P 500 returned roughly seven percent annually after inflation in 1928–2023, according to S&P Global data. Reinvesting dividends and holding for twenty to thirty years roughly doubles the capital every decade. Stocks are ownership in a real business whose value grows with the economy — EUR/USD has no analogue of fundamental growth, it oscillates around a long-term mean.

This path is right if you are saving for retirement and want capital to compound over 15–30 years. You hold a full-time job and do not want to stare at charts daily — a quarterly portfolio review is enough. You value tax simplicity — in Poland equity gains are settled on PIT-38 at a flat 19 percent rate (the Belka tax). You accept growth of 7–10 percent annually and are not chasing quick money.

European context: the Polish WIG20 as a vehicle for domestic exposure showed weakness over the long run. From its 2007 peak to the end of 2023 the nominal index value was about 40 percent lower, while on a total return basis with dividends reinvested (WIG20TR) the cumulative result is positive at roughly 30 percent. By contrast the S&P 500 tripled in the same period. If you pick a broad index, lean on a global ETF (MSCI World, S&P 500) and treat the domestic WIG as a supplement worth ten to twenty percent.

When to choose forex and CFDs

Leveraged forex makes sense for a narrow group of investors. It is not an alternative to a long-term equity portfolio — it is a separate activity that can be run in parallel, with a small fraction of capital, accepting the high beginner failure rate.

Forex is the right path if your evenings are open and you need a market outside business hours — between 19:00 and 23:00 Central European Time the New York session on EUR/USD is at peak liquidity. You enjoy comparative macro analysis (Fed against ECB, US inflation against the euro area). You accept losing your first, second, sometimes third account as part of learning a craft rather than a financial catastrophe. You treat forex as a hobby or a second profession, not a passive investment.

A practical recommendation for somebody who wants to try both worlds: 80 percent of capital in a global equity ETF as the long-term base, 15 percent in individual dividend or growth stocks whose business model you understand, and 5 percent in active forex from a micro lot with conservative leverage, after a full demo cycle. The discipline this split requires deserves at least three months of journal work before any live forex position is opened.

The most common traps when choosing

The first trap is comparing single periods. Somebody shows a chart of EUR/USD that fell from 1.13 to 1.07 in three weeks in March 2020 and claims that on forex you can earn in a month what would take five years on equities. What they leave out is that the same move in the opposite direction wipes a retail account on 1:30 leverage. Long-term statistics, not a single move, decide whether a strategy makes sense.

The second trap is treating ETFs and forex as an "either or" choice. These are two different instruments with two different risk profiles. ETFs are an investment, forex is a trading activity. A blended portfolio is the most common healthy scenario for somebody whose day job sits outside finance.

The third trap is 1:500 leverage at brokers outside the European Union (Saint Vincent, Marshall Islands, Mauritius). The price for that choice is no investor compensation cover, no regulatory oversight, regulatory and tax risk, and a much higher probability of liquidation on a single market move. A retail account at 1:500 typically wipes on a quarter of one percent adverse move — a move EUR/USD sees almost every London session.

The fourth trap is failing to distinguish between owning a share and holding a CFD on it. Ownership carries dividend rights and voting rights. A CFD gives only price exposure — dividends are booked as account adjustments, taxed differently, and broker-failure protection is lower than for shares held with the central depository.

European context — KNF, GPW and your portfolio

The Komisja Nadzoru Finansowego (KNF) supervises the Warsaw Stock Exchange and all Polish brokerage houses (XTB, mBank Maklerski, BOSSA, IPOPEMA), enforces disclosure obligations and applies the ESMA regulations on CFDs for retail clients. A Polish or other European resident has two solid options: a domestic firm with a KNF licence, or an EU broker operating in Poland under an ESMA passport (DEGIRO, eToro EU, IG Europe). Both deliver the full EU protection package, and the same logic applies in the rest of the European Economic Area through the local national regulator.

Tax settlement for a Polish investor is relatively simple. Profits from shares listed on GPW and EU exchanges are settled on PIT-38 at a flat 19 percent rate. Polish brokers issue a PIT-8C statement, foreign brokers do not — you sum trades yourself and convert into the local currency at the central bank exchange rate of the day. The same applies to CFDs on forex.

Three actions to take this week

1. Define your time horizon. Open a spreadsheet and answer three questions: how many years are you setting this capital aside for, do you need cash flow along the way, will you accept a thirty percent drawdown during a bear market. If the answers are 15+ years, no current cash flow, drawdowns acceptable, then a global equity ETF — not forex — is your primary instrument.
2. Tally your current portfolio across both classes. Write down the full portfolio and split it across shares (domestic and foreign), ETFs, cash, bonds, deposits and CFDs on forex. If the forex share of liquid capital exceeds five percent, you carry too large an exposure to a class that statistically grinds down retail accounts.
3. Open two demo accounts in parallel. One with a stock broker regulated by KNF (XTB, mBank Maklerski, BOSSA) and buy on paper one S&P 500 ETF and one WIG20 ETF. The other a demo with a CFD forex broker, where you enter a realistic position of 0.01 lot on EUR/USD. Track both for three months. This will show you in black and white which of the two worlds you actually want to work in.
4. Check the tax consequences of your plan. For shares and ETFs — does your broker issue a PIT-8C statement, or do you need to file from scratch. For CFD forex — how does the broker report swap rolls and commissions on the year-end statement, so that you can claim costs on PIT-38.
5. Write down your allocation decision. On a sticky note above the monitor or in a Markdown file: "X percent in a global equity ETF, Y percent in individual stocks, Z percent in forex from a micro lot". Without that written decision the first market wobble pushes you into irrational reallocation under emotion.
