It depends..!
It’s easy to say depends but difficult to give accurate figure at any given point of time and the reason being each fund house or an Asset Management Company (AMC) like SBI Mutal has the freedom to charge a maximum of 7% on the invested amount as exit load (now that the entry load is scrapped)
So each of these AMCs have the freedom to define exit load for each of their schemes and the duration till which they expect the investor to stay with them popularly called as lock-in.
So, always know the exit load and the lock-in period before investing into a mutual fund. It will be a available on AMCs website or some popular websites.
This way, they are safeguarding interst of their other clients who stay invested because every time there is a withdrawl or redemption from a customer, that fund house has to sell shares in effect bringing down the share price. Now the problem is..when you wanted to sell, people ask for a lower price and when you wanted to buy, they demand higher price.
With lot’s of complications on Mutual funds, it may be wise for a short term investor to buy Index funds or even better ETFs where commissions are less and easy to transact.
