Stock market: Is Investing in Equity is more about EQ(Emotional Quotient) than IQ(Intelligence Quotient)?

I shall keep this answer short.

Investing in markets is about knowing a whole bunch of things.

1. Fundamentals
2. Technicals (Very Important)
3. Business cycles
4. Manipulation of markets, news and fraud practices.
5. Market cycles. When bullish market discounts all bad news and when bearish it discounts all good news.
6. General health of economy.
7. Ability to differentiate between bad news and real bad news.
8. Art and science of averaging, pyramiding etc.
9. Investing psychology

Thus not just EQ, IQ but a whole bunch of things. Remember earning money in markets is simple (Just click of a button) but not easy.
