I've seen answers here recommend index mutual funds and want to know what are some mutual funds available in my market (Mexico). I'm interested in funds available on the Mexican stock market (BOLSA) or available in Mexico and holding BOLSA-listed securities.
The recommendations you read were, very probably, talking about US listed funds in US dollars.
The mexican Bolsa de Valores says that they list over 600 mutual funds so "Yes" you can invest in Mexico using Pesos if that is what you want. You need a Corredor de Bolsa or mexico broker. Here they are.
Most international investors use exchange traded funds ETF because theirs fees are cheaper than mutual funds. The ETF are mostly listed and traded in us stock exchange. Here they are.
US mutual funds are in dollars and, because you are living in Mexico, you will have a currency risk and probably taxes. Mexico mutual funds in Pesos do not carry any currency exposure unless the companies involved do business in the United States. You have to think about your currency exposure.
