What are the modalities of investment? There are modalities of investment investors must know. If you are already investing, you might have encountered these modalities. There are three main modalities such are those that can establish a fully new operation in the host country (greenfield investment), engage in a new partnership with an existing company (a joint venture), or acquire an existing firm (through a merger or acquisition) in the host country. You might have invested through a joint venture. In my case, I only invested in Mutual Funds and Stocks under joint ventures. What about you, what is your investment modality?
