I wonder if anyone can share from personal experience ... if there is a such thing as simple portfolio Allocation Strategy? Here is a sample scenario. Type of account - equities, strictly ETFs Amount - $100K portfolio Hold time - anywhere from few weeks to a 1 year of holding. Industy - any/all Broker/fees - IB No leverage of any kind. Without going into weighted averages, sharp ratios, etc...I wonder if three is simpler method that anyone has used/using. I know some funds or investors do not invest more than 2-3% of the portfolio in a single position. So in case my scenario...it's $2-3K...not sure how practical in my case...just an example. I also read about Mehmet Okumus in one of the wizard books where he maintains a top 10 positions only...in other words if he wants to add another stock, say 11th candidate then one position must be liquidated to make room. But I can't recall how that top 10 was allocated...if equally divided up or... Anyway...thanks for any suggestions and good feedback.
