    Investing through ETF

    ETF (Exchange Traded Funds) are investment funds that are listed, and therefore offer great liquidity, and which replicate an index. An index is a transparent investment methodology. In other words, ETF are basket of securities, equities or bonds, already diversified and which makes portfolio management much easier. ETF are also very competitive in terms of management fees.

    ETF are baskets of securities which follow a transparent methodology called index. It makes investing very transparent. One knows at every moment which securities are amongst the basket. It makes it easier to run a diversified portfolio. For example, with an ETF on the financial sector, you only have to buy one ETF and you get exposure to 17 securities of the financial sector.

    A complete selection of ETF

    There is a mechanism well known and used by the fund managers which allows to monitor the risk : bonds and equities are moving in opposite direction depending on the market conditions.

    With equities, one owns part of a company. With bonds, one lends to a state or a company. When the economy is doing well, equities are going up and so do the interest rates. It means that bonds, which are mechanically evolving with interest rates, are going down. On the contrary, when one fears for the wellness of the economy, one seeks for a safe heaven, in a flight to quality. The « real money » (pension funds, insurance companies, sovereign wealth funds, etc.) is a big player in this game. That is why the mechanism has been so persistent over the decades.

    At Marie Quantier, we have divided the market conditions into four states. The first, called « expansion » is when economy is improving and equities are undervalued. With no surprise, it’s when we recommend investing mostly in equities. The second one, called « Panic », is when economy is deteriorating and equities are overvalued. Again, quite easy, we recommend not to invest one penny in equities in such a market condition and to protect one wealth by investing in sovereign bonds. Finally, there are two transition states called « euphoria » and « recovery ». In those market conditions, we recommend having half ones wealth invested in corporate bonds.

    It’s now easy to understand why one needs a complete set of ETF amongst all the asset classes to correctly risk manage one portfolio. And that’s what you get with the platform Marie Quantier.

    Investir au moyen des ETF

    Les ETF sont des fonds d'investissement côtés en bourse qui suivent un "indice" qui est une méthodologie transparente. En d'autres mots, les ETF sont des paniers de titres qui permettent de construire facilement des portefeuilles d'investissements diversifiés à un coût compétitif.

    Cela permet de connaître exactement, à chaque instant, les titres qui composent l'ETF. Par exemple, au lieu d'acheter les 40 actions du CAC40 pour diversifier ses investissements dans toutes les grandes entreprises françaises, il suffit d'acheter un seul ETF sur le CAC 40.

    Les ETF présentent les frais de gestion les plus compétitifs de l'industrie financière. C'est plus équilibré pour les investisseurs particuliers, surtout si l'on compare aux frais pratiqués par les fonds classiques ou les produits structurés.

    Une sélection d'ETF minutieuse en parfaite indépendance des groupes bancaires

    Notre infrastructure nous permet de définir les phases pendant lesquelles l'économie s'améliore et les actions sont sous-valorisées : "expansion" (allocation en faveur des actions), les phases pendant lesquelles l'économie se détériore et les actions sont sur-valorisées : "panique" (allocation en faveur des obligation d'États qui sont des prêts aux États) et les phases de transition : "Euphorie" et "Récupération". Pendant ces phases de transition, les obligations d'entreprises présentent les meilleures perspectives.

    Marie Quantier sélectionne des ETF qui couvrent toutes les classes d'actifs en euros et en dollars : Obligations de court terme, obligations d'États, obligations d'entreprises solides ("Investment Grade") et les ETF actions. Pour les ETF actions, nous couvrons tous les ETF sectoriels commercialisables en France.

    Nos équipes effectuent une présélection rigoureuse des ETF : versements des dividendes, réplication des indices dont les variations peuvent être estimées avec succès par des analyses quantitatives, liquidité suffisante sur le marché, spread bid/ask suffisamment étroit. Surtout, il faut que l'information financière concernant l'ensemble des composants des ETF soit disponible et fiable.
