Vijay told CNBC-TV18, " Subex is perhaps most difficult company to understand in the midcap IT space because they are essentially a product company and apart from most of the other Indian companies which are sort of a garage where people come and park their cars and get it serviced type of thing. So Subex has gone ahead and done a very risky business model - it is totally into product."
He further added, "Risk with these types of companies is that they are going to have very volatile topline and bottomline. So you have to admit that but I should give it to Subex that in the financial services space, that product is perhaps second only to Infosys."
