What happens if I invest 700,000 one time in a mutual fund like Reliance Small-Cap?

Well, the Rs 7 lac invested grows. Had you invested it 5 years ago, it would have doubled every 2 years, an astounding growth rate! You would have receive about 34 lakh rupees by now.

However after the market correction, the fund has fallen since January. While no one can predict the future markets, small cap funds are volatile and staying invested for a longer duration can yield good results.
