I am looking to invest for long term would like to start with lump sum investing in stock market.
I also had a very similar question but then I came across this article written by Chintan Sir who is also Sebi registered. And his answer made me think about investing in different perspective.
I am sharing his reply in Quora to a similar question which might be of interest to you.
At the same time also came across another video in which Chintan Haria explains how to be overweight and underweight between the growth stocks and value stocks.
Hope this answers all your question.
