CFD or Spot Market: The Differences That Matter

Buying a stock directly and trading a CFD on that same stock might look like the same thing at first glance: both track the asset's price. But the mechanism behind each one is quite different, and understanding that difference avoids surprises when calculating gains, losses, and costs.

What the spot market is

In the spot market, you actually buy the asset. By acquiring a stock, you literally become the owner of a fraction of that company. Payment is usually made in full, with no built-in leverage by default, and settlement happens within a period set by the exchange.

That means to buy R$ 10,000 worth of stock in the spot market, you actually need to have the R$ 10,000 available. If the price rises 10%, your holdings in that stock become worth R$ 11,000. If it falls 10%, they become worth R$ 9,000.

What a CFD is

A CFD (contract for difference) is a derivative instrument that lets you speculate on an asset's price change without buying the asset itself. When you open a CFD, you and the counterparty agree to exchange the difference between the opening price and the closing price of the position.

In practice, this means you never actually own the referenced stock, currency, or commodity: you're only trading its price change, which also lets you trade both rises and drops in the asset with equal ease.

The difference that matters most: leverage

CFDs are usually traded on margin, which lets you control a larger position with a smaller initial capital. This amplifies the result, both up and down, in the same proportion.

Here's a simple comparative example, using a hypothetical stock trading at R$ 100.00, with a 5% rise over the period:

• Spot purchase of R$ 10,000: with the 5% rise, the result is a gain of R$ 500.00, or 5% on the invested capital.
• CFD with 20% margin on the same R$ 10,000 exposure: the capital deposited as margin is R$ 2,000.00. With the same 5% rise in the asset, the gross gain is still R$ 500.00, but now it represents 25% on the deposited margin.

The same logic applies to a 5% drop: in the spot market, the loss would be R$ 500.00 (5% of the invested capital). In the leveraged CFD from the example, that same R$ 500.00 loss would represent 25% of the deposited margin. It's this amplification, on both sides, that demands extra attention to risk management when trading CFDs.

Ownership and asset rights

Another relevant difference: someone who buys a stock on the spot market actually becomes a shareholder, entitled to any dividends and to voting at shareholder meetings, depending on the type of share. Someone trading a CFD on that same stock doesn't acquire any of those rights, since they're only speculating on the price change, without holding the actual asset.

Costs and holding period

Spot positions, once paid for in full, usually don't generate additional costs just for being held over time, aside from any custody fees. CFD positions, being leveraged, usually involve an overnight position-holding cost, charged when the position stays open from one day to the next, which makes CFDs an instrument more associated with shorter-term trades.

Which one to choose

There's no single universal answer, only what fits each person's goal. Investors who want to build a long-term position, receive dividends, and not worry about daily margin adjustments tend to prefer the spot market. Traders looking to trade both rises and drops over shorter periods, with less capital tied up per position, tend to be drawn to CFDs, like the ones offered on Astron.

In both cases, there's real risk of capital loss. With CFDs, because of leverage, that risk can include losses greater than the amount initially deposited as margin, depending on the contracted conditions, which demands even more discipline in setting loss limits before opening any position.

One simple practice helps a lot with this: before opening any position, write down the maximum acceptable loss for that trade and the position size compatible with that limit. This applies both to spot buyers and to CFD traders, but it becomes even more important when leverage is involved.
