Take Minakshi Goradia who, despite a generous touch of grey in her hair, is actively monitoring her portfolio of about 200 companies. Or R. Karnad, aged 72, who spends the better part of the year following up on the 400 companies he has interests in. Chance or circumstances, say these people, have landed them in this all-consuming vocation. Goradia, an advocate by profession, took on the portfolio of her mother and uncle, themselves active investors since the '50s. Right from his teens, Mahesh Keswani took to "finding a safe avenue to invest the family money". Ajitsinh Bhatia, 62, got hooked to the business when the sale of his first investment, a single share of Thackeray & Co, earned him Rs 160 in 1954. In due course, each one of them left his profession prematurely to concentrate on stockmarkets.
