Can I buy & sell open-ended mutual funds any time?

#3
Yes. Open-ended funds work almost like a Bank Account. You can invest on any working day in any scheme you want to & you can take back the investments in part or in full on any working day from most of the schemes within 72 hours – by cheque.
This kind of information is available on the websites of all of the major AMC’s. you can check out Reliance Mutual Funds website. They have all of the required information on buying and selling mutual funds.
