म Mutual fund मा लगानी गर्न चाहन्नछु र यसमा लगनी कसरी गर्ने । Robinhood app फ्री छ तर यसमा Mutual fund मा लगनी गर्न मिल्दैन रहे छ तेसै ले Mutual Fundमा कसरी लगनी गर्ने ।

Just wait, magorkhe aucha advice dina.

open a account in Vanguard. They have the lowest management fees. Also the website will explain you which Ira to open.

how risky is mutual fund and what kind of return can you get? from my research i have found out that it is the most conservative form of investment and you can see return of around 11% . is that true?

Mutual Fund कती को जोखिम युक्त छ । Fedility चही कस्तो छ Mutual Fund को लागि मैले यसमा हेर्द कुनै कुनै Mutual Fund फ्री म लगानी गर्न मिल्ने रैछ ।
तेसै ले Mutual Fund को लागि Fedility राम्रो कि Vanguard ।

Mutual funds combine individual stock together and make a package. So they have different levels of risks depending on the type. As an example for Vanguard Target Retirement 2045 Fund :Asset allocation as of 09/30/2017 is 90.01% Stocks 9.97% Bonds 0.02% Short-term reserves. Meaning this fund is very aggressive so has higher risk potential. This would be best suited for people in their 30s who want to retire around 2045-2050, for them short term volatility does not matter, even if market goes down couple years like 2008 it will rebound say 2017 market. As time passes, the allocation will be changed to more bonds and less stocks.
Vanguard vs Fedility chain I cannot answer, but they are very similar in nature. It all depends on who you want to invest your money with. Best way to compare them is the management fees and how much it costs to buy funds and shares. Hope this helped. Here is the fund I used for example:

Index funds would be the closest alternative to mutual funds that you can buy on Robinhood platform. Both index and mutual funds may hold a mixture of stocks, bonds, and cash. Index funds tend to have lower management fee over mutual funds.
