One reason is good enough to own them: 5 midcap stocks from different sectors and upside potential of upto 27 %

While there are phases, where they come under pressure, the fact remains that the last ten years best returns have come from mid-cap stocks. So, probably if one is not owning then the return even in the longest of the bull run will not be very high. One of the reasons why mid-cap stocks are able to do well when an economy like India grows at a faster pace is that mid-sized companies are able to improve their operating matrix. Whether it is the cost of capital which comes down, new markets getting opened, it is mid sized companies operating in certain sectors which see faster growth. But the bigger question is which stocks to own, when to buy them and what should be the horizon for which they should be bought and last but not least there has to be one reason why one is buying that particular stock. It could be market size, company being the leader or even a company having a library which no one can replicate.
