This is not just something from yesterday it like this for long time.
Most of investors know this but sometimes focusing on something small can be huge profit. Probably most popular thing in this is "Focus on the Long Run". One of the biggest traits is to have an uncanny ability to focus only on long term performance. Off course these things are easier said than done. From time to time we hear or read from many investors about their philosophy of investing for the long term, from this every one have some point of view on this. Short is also there but this is for experience investor with huge experience, at least this is my point of view. Some play on for me think its old school model "Quantitative Vs Qualitative". For this type research is the most widely used tool to increase and brush-up the stock of knowledge about something and someone, possible investment. In the field of investments there are two standard ways of conducting research qualitative or quantitative. Qualitative relies on verbal narrative like spoken or written data, while the quantitative uses logical or statistical observations to draw conclusions.
With so many possible techniques or help tools how days, it could come to conclusion that its much easier how days then before. So many are going for this big risk big results.
