This post is personal. We all have strategies on trading and the most important things for any trader in my opinion is to finally discover his/her strategy which suites there emotional temperament (pessimist / optimist). intellectual capacity ( children with a few simple rules trade better then many seasoned smart adult analysts/ proven back-testing results) , and their life style (how much time do you have, and the time frame you feel comfortable with).
We trade up to 25 stocks/commodities and about 10 at any given time and are on a mostly weekly cycle. VTI is one of them. 90% of the stock we trade have similar wave patterns (as this cuts down on analyzing time), we short for a hedge. The commodities we trade are more on the monthly cycle trade commodities less often. We analyze with indicators, Elliott and trendlines, we try to ignore the news media. When it comes to Elliott counting we believe the count which make you money is the "right count". Our simple rule is BUY low and SELL high, when his is done consistently you will inevitably see your portfolio go up,.... it works.
Anyway if you have thoughts please feel free to share, again I am sharing a very personalized trading plan this may not fit you temperament, style of trading or your time frame.
