I live in India, I've invested in some equity mutual funds (that invest in the domestic market). Each of them has some money in mid-cap stocks and some in large-cap. In fact, one of my funds was primarily mid-cap when I started investing, but now has a substantial large cap component.
Keep in mind that there aren't consistent definitions of where the boundaries lie. So I'll go with the one BSE uses:
Eligible universe shall comprise of companies aggregating 98.5% of average market capitalization. This list shall be categorised under large-cap, mid-cap and small-cap segment based on 80%-15%-5% market capitalization coverage respectively.
Given all this, how do I find out what percentage of my money is in large-, medium- or small-caps? The reason I ask is that if I find that more than 80% of my corpus is large-cap, I'll make further investments in mid-cap. Conversely, if I find that less than 80% of my corpus is large-cap, I'll make further investments in large-cap.
I want to rebalance my portfolio to not have a bias towards or against large-cap. I can do that only if I know what percentage of my portfolio is large-cap.
