For long term investment, is it better to...
1) Time the market and invest on stable blue chips for substantial dividend payout
or
2) Apply DCA on ETF
I'm talking about sg context
You've sort of got two questions conflated into one here.
Option 1 is "time the market, and buy a narrow basket of stocks"
Option 2 is "don't time the market, and buy a broad basket of stocks"
Those are two different things, though they reflect two main priorities:
Option 1 is "I think I can trade better than the market as a whole"
Option 2 is "I don't think I can trade better than the market as a whole, so I'll be satisfied with an average return".
The problem is that option 1 is sort of self-defeating! Think about it like this:
1) Before fees, the average investor in option 1 is going to earn the same as the average investor in option 2.
Why is it so?
The total money invested in the market is going to earn the average market return, and the money invested in option 2 is going to earn that same return. So the money invested in option 1 is, on average, going to earn that same return. Before fees.
2) After fees, the average investor in option 1 is going to earn less than the average investor in option 2.
Why is it so?
Actively managed funds, and active individual traders, tend to trade more often: so they run up higher transaction costs and more spread costs. If they have the same average return before fees, and option 1 has higher fees, then after fees, option 1 will have less money.
3) You are probably an average investor - in fact, probably below-average.
Why is it so?
The reason banks' trading desks and market-making companies are so fabulously profitable is that most of their retail customers systematically lose money. Active trading, especially for individual traders, is basically a firehose of cash from your pocket to the banks' trading desks.
So option 1 doesn't just start with the same returns before fees - it starts with lower returns before fees, and has higher fees.
4) Therefore, you will probably end up with less money in option 1 than in option 2.
5) So why not just skip straight to option 2 and save yourself some time?
