Stocks vs CFDs: why they're not the same in Spain

If you've ever seen an ad saying "invest in Apple shares from €10" or "trade the world's largest stocks commission-free," you probably weren't sure if you were being offered an actual share or a derivative based on its price. This is no small matter: the difference between shares and CFDs (Contracts for Difference) determines whether you own something or are simply making a bet on how a price will move.

In this article, we explain what a CFD is, how it differs from a real stock, why leverage completely changes the risk profile, and what signals you can use to understand what each platform is really offering. It's not about simply stating that one product is better than another; it's about ensuring you understand what you're signing up for before investing your money.

What is a CFD and how does it differ from a stock?

A CFD is a contract between you and a platform in which both parties agree to exchange the price difference of an asset between the time you open the position and the time you close it. The name says it all: Contract for DifferencesYou don't buy anything physical, you don't acquire any title, there is no transaction involving the asset itself.

This has a consequence that many novice users don't understand until they've already traded: if you open a CFD on a company's shares, you never actually own a single one of those shares. You have a contract with the platform, and that platform is your counterparty in the transaction.

The fundamental difference with an actual share is one of ownership, not a technicality. When you buy a share, you become the owner of a tiny fraction of that company. This shareholder status comes with specific rights: receiving dividends if the company distributes them, voting at shareholder meetings, and receiving the financial information that the company is required to publish.

When you open a CFD, on the other hand, you only have a speculative position on how the price of that underlying asset will move. There are no shareholder rights, no ownership, and no actual dividend, although some platforms try to artificially replicate their effect.

This is the root of the difference between stocks and CFDs, and it's important to understand it clearly before proceeding: A stock is an asset you own, a CFD is a contract you sign.

Leverage: Why CFDs Amplify Gains and Losses

If there's one feature that most clearly distinguishes CFDs from real shares, it's leverage. When you buy a share, you pay 100% of its value: if you want €1.000 worth of shares, you put down €1.000. With a CFD, however, you only deposit a fraction of that total value, known as margin, and the platform allows you to control a much larger position.

Let's take an example with leverage of 1:5. You put in €200 of margin to control a €1.000 position. If the asset rises by 5%, your profit is not 5% on the €200 you deposited, but 25%: €50 profit on your actual capital.

It sounds appealing, and in fact, that's how CFDs are often presented in aggressive advertising. But the mechanism works exactly the same way in the opposite direction.

If that same asset drops by 5%, your loss also multiplies: You don't lose 5%, but 25% of your capital, that is, those same €50 out of your €200 deposited. Leverage amplifies gains and losses symmetrically. There is no version of leverage that only works in your favor.

This amplification is not an opinion or an exaggerated warning: it is a fact that regulations require us to disclose. CFD providers operating in Spain are obligated by CNMV and ESMA regulations to clearly display the percentage of retail clients who lose money trading these products. This figure varies depending on the platform and the period analyzed, but the range typically observed in the sector is broad and significant.

Four differences that the basic investor should know

Beyond leverage, there are four key areas where real stocks and CFDs differ significantly. Understanding these areas gives you a clear framework for understanding what you're actually trading on each platform you consider.

Ownership is the most important aspect of this comparison: with a physical stock, you own something that exists independently of the platform where you bought it. With a CFD, your position only exists as long as the contract with that specific platform exists.

Rights derive directly from ownership. If you're a shareholder, you receive the dividends the company distributes, you can vote at shareholder meetings, and you have access to mandatory financial information. None of these rights exist in a CFD, even though some platforms offer an "adjustment" that simulates the dividend effect on your account.

In terms of costs, buying physical shares usually involves a purchase commission and, in some cases, a custody fee for holding the shares. CFDs, on the other hand, generate revenue for the platform through a wider spread between the buy and sell price, as well as a daily financing cost for positions held overnight.

Finally, regulation. Both types of platforms may be authorized to operate in Spain, but under different frameworks. Entities offering real shares are registered as investment services firms with the CNMV (Spanish National Securities Market Commission). CFD providers are authorized as financial institutions, but operate under specific regulations for derivative products, with particular transparency obligations, such as the loss notification mentioned earlier.

The specific risks of CFDs

Before trading CFDs, it's important to be aware of four specific risks that go beyond leverage. The aim here is not to cause alarm: CFDs are a legitimate and regulated product, with their own risks, just like any other complex financial instrument.

The first risk is the loss of capital, which can reach 100% or even exceed that amount if the market moves against you with leverage. Regulated platforms in Europe are required to offer negative balance protection for retail clients, preventing you from ending up owing money to the platform. Even so, it's advisable to verify that this protection is active before subscribing to any service.

The second risk is the overnight maintenance cost, also known as swap. Each day a CFD position remains open incurs an additional financing cost. For trades lasting only a few hours, this cost is marginal. However, for positions held for weeks or months, the accumulated cost can become significant and eat up a large portion of the potential profit.

The third risk relates to the dividend. Some CFDs include a "dividend adjustment": When the underlying company distributes a dividend, the platform credits or debits your account with the equivalent amount. However, this is not, under any circumstances, the same legal instrument as an actual dividend derived from being a shareholder of the company.

The fourth risk is counterparty risk. When you trade a CFD, you're not in the real market buying and selling the underlying asset: your counterparty in the trade is the platform itself. This means that the financial strength and reputation of that platform are an additional risk factor that doesn't exist when you buy a share through a broker who simply executes your order in the market.

How can you tell if a platform offers real shares or CFDs?

With all this information, you can now apply some practical signals to identify what each platform is really offering you before registering.

• If the platform advertises that you can "invest in stocks" with leverage, it is almost certainly offering you CFDs on stocks, not the stocks themselves.
• If you see a visible notice about the percentage of retail clients who lose money, that's a clear sign that the platform trades CFDs: it's an ESMA regulatory obligation for this type of product, and real shares don't carry it.
• You can check the CNMV registration directly at cnmv.es: entities authorized to manage and transmit orders on real securities are listed in a different register than providers of derivatives such as CFDs.

If you're looking for real shares, the recommendation is simple: specifically look for authorized platforms such as investment services firms, or tied agents of investment entities registered with the CNMV (Spanish National Securities Market Commission). This regulatory nuance is, in practice, the most reliable way to know what you're buying before putting your money on the table.
