MaB investors

Am I a MaB investor?

Investors need to find out about the company they wish to invest in, what their forecasts are, future projections and possible risks.

The first decision a saver must make when deciding where to invest, is exactly how much risk they are prepared to take on, bearing in mind that the highest returns usually go hand in hand with the highest risk.

Investments in small companies with growth projects are normally associated with higher  risk levels than investments in larger companies whose business  activity is more consolidated in their respective markets.

In order to be able to assess all investment opportunities on the alternative market, investors need to find out about the company they wish to invest in, what their forecasts are, future projections and possible risks. This way the investor can ascertain which securities portfolio fits their investment profile.

If we take into account the investor's profile at all times, we will be able to make the best, most logical and strategic decisions when establishing and managing an investment portfolio.

Diversification is an investor's ally, regardless of their profile. By having a diversified portfolio of financial products, our investment will be exposed to less risk.   

Investors must see that  MaB is a market for growth companies with medium- to long-term business projects and often with higher growth forecasts than consolidated companies in each sector.

All companies listed on the MaB provide detailed information on their business and forecasts in the Information Document they are required to submit. This Document is available to investors on the MaB website. Investors are advised to read the Information Document carefully and in its entirety before making any investment decision on MaB securities.

MaB companies are smaller than those which are listed on the stock market and are looking to raise finance on the market for their growth projects. Various MaB companies have successfully undergone significant growth processes and are now larger than those on the stock market. So that the size of the securities does not affect a minimum liquidity level on the market, the MaB has liquidity providers.

These intermediaries provide sales and purchase positions during the market session under conditions which are supervised by MaB and are totally independent from the company itself. Its main objectives are: to guarantee transactions are liquid, ensure sufficient trading frequency and reduce fluctuations in price which are not caused by market trends.

MaB is open to all kinds of investors: private and institutional investors, residents and non-residents.

How to invest

The process of investing in securities listed on MaB is just the same as with securities listed on the stock market: the same intermediaries are used and the costs are the same.

Who should I contact?

Investing in MaB companies is very straightforward. These securities are traded on the Spanish market's electronic platform. So, just as we can invest in Telefónica or Inditex on the stock market, we can invest in these securities.

The best way to invest in MaB securities is to contact a market member (MaB members), as they are specialist intermediaries with direct access to the MaB.

Our usual intermediary can channel purchase and sale orders for securities listed on MaB. First you must open a securities account. This account will be used to administer the investor's securities portfolio (sales/purchases, subscriptions, dividends, GSM attendance, etc.). All cash movements associated with market trades will be carried out in this account.

When the investor signs the contract to open this account they must be made aware of the applicable fees and commissions and the services offered by the intermediary (type or orders, how these orders can be sent: internet, phone, etc).

How much does it cost?

The cost charged to the investor when buying/selling on MaB comprises the following three items:

  1. Trading costs: these range from 0.20 to 0.35% of the cash amount for each trade. Fees tend to be lower for intermediaries offering online services. A minimum amount per trade is often included.

    Pursuant to prevailing legislation, all intermediaries must publish their fees and inform the CNMV. This way investors are aware of what fees they will be charged from the start.

  2. MaB fees: these are the same as those applied on the stock market; the amount is proportional to the cash value of the transaction. A fee of €1.10 is applied for transactions under €300, rising to €13.40 for transactions over €140,000.
  3. Settlement fees: These are also the same as those applied to transactions involving stock market listed securities. A fixed fee of 0.0026% on the cash value of each transaction, with a minimum of €0.10 and a maximum of €3.50


MaB securities are traded on the SIBE electronic platform.

Depending on their size and trading volume, securities can be traded on the continuous market or on the Fixing system. Under this modality, securities remain under auction during the entire session, with two closing periods, one in the morning (12:00) and another in the afternoon (16:00).

The trading modality is included on the information file available for each security on the website.

How can I track my investment?

MaB website offers prices for all companies along with other significant information to be able to track your investment and make relevant decisions: financial information and other information released by companies, research and valuations by professionals and investment portfolio management tools.


The market section on MaB website shows both the session and the historical prices.

It is also common practice for an intermediary to offer investors the possibility of checking session prices on their own website.

The main financial media also offer detailed market information online.
