I posted earlier on this

There are 4 investing styles

1: Day Trading --- Stocks are hold for no more than a few days, and most of time postions closed within same day

2: 波段 --- Trying to get in and out of stock on the minor trend within a major trend. Timeline wise could be 1 to severak weeks

3: 趋势 --- Follow the main trend of stock and hold it until trend reverse. For example, in a typical elliot wave, you hold 12345 waves, even though wave 2 and 4 are corrective waves, and only exit position when big ABC correction starts after 5 waves. Timeline wise, this could be several months or years

4: Buy and Hold --- Never sell and trust US economy and buy at any major US market correction

My investment style is #3 above
