Great start. Thanks for articulating your thoughts.
IMO, only few companies from your list qualify for long term of 10 years i.e. ITC, HDFC group of companies, PIDILITE. Rest all will give pain down the line… Please monitor them periodically and kick them out mercilessly if fluctuations are wide.
I have some long term holding PF for public view if you wish to look for alternatives. But do your own due diligence and research before investing.
Disc. invested is some above names.
