I know that STCG for debt funds applies if we sell within 3 years. But from when is this 3 years calculated if a person did not purchase all of his mutufal fund units at once but purchased at random intervals?
Say a person purchased 100 units in 2017 January, consider this as A and purchased another 100 units in 2017 February, consider this as B. If he wants to sell 50 units in 2020 February, which 50 units would he be selling? from A or B? How to determine from which installment he is redeeming? Installment A completed 3 years, installment B completed 2 years and 11 months. So is he redeeming A? or the 3 years time starts from the day he made his first installment to the day he is selling and the later installment dates do not matter?
Thank you.
