Dear Raunak,
You views are baised depicting that for delivery based trading (investing) one has to necessarily follow FA and have a thorough knowledge of the economy, sector, industry, company etc (the top down approach etc etc). A good grasp of PE, EPS, PBV, earnings, discounted cash flow etc etc.
This is just a one sided view, delivery based investing can be done even with TA and just zero knowledge of FA or anything about the ecomony and other stuff. The monthly, quarterly, yearly charts can still give you patterns, trends, break outs, resistance, support and all what we follow for intraday, swing trade and all. Taking delivery means you want to hold it for a large period of time than what the dervatives contract would allow and without levearging so there is no pressure of MTM losses / margin calls.
The charts talk : irrespective of what TF we look at.
On your comment on deciding what TF a trader wants to trade. Refer AW10 comment that short term trading (Intraday, swing) can help meet your living expenses but cannot create wealth. Big money is made in big time frame.. So as the fund size increases, one will have to allocate funds to higher TF investing / trading, which is essentially nothing but delivery based investing, which could be for a period of 6 months, a year or two or more too. e.g. as a day trader, say I have a method which is scalable to use upto 20 L of trading capital, for swing trading I may scale up to use another 50 L, but what if I have 2 - 3 -5 Cr ...at my disposal, I cannot deploy them to day trade because my method and resources are not scalable to handle this amount. Hence necessarily I will have to invest it for larger period (and also 'safer' assets - by not leveraging) through delivery based trading. And there is no conflict in ones mind as you need not track such investments daily, probably once a month or twice a month is good enough.
To sum it up, as I have quite often written elsewhere, it is the fund allocation which is the key for success even for day traders to create wealth. So even for a day trader or a jobber his bread may come from his daily activity, his butter will come from long TF investments / trades.
Regards,
