Why Fundamental Factor is Required if The Technical Factor is Enough to Determine Market Bottom?

Absolutely not. Earnings and market fundamentals often don’t turn around until well after the market has hit bottom. That means taking those factors into consideration would cause you to be very late to the party. Remember, there has never been a new bull market without a follow-through confirmation preceding it on one of the three major indexes. Therefore, taking underlying earnings and fundamentals into consideration is not only unnecessary but could be very costly.
