What is the strategy to buy back a stock (ETF) once it dips below its 200 day moving average and was sold??

Congratulations ETF Trends. You are right and were right from the get go.

I am trying to make this point be understood in real estate also where sellers still do not do their homework.

Great question Charles!

We did a post on it to answer your question, hope this helps.

Thanks, Tom

Thanks for all the great information given at ETF Trends.
However I strongly disagree.
I used to follow the IBD rules as well and sell when it dropped 8 % from what I paid for the ETF.
Then within a month after I sold it 9/10 times it came back higher than what I paid for it.
Now since I am a long tem investor I do not follow those rules I follow my own.
Even with the sell off recently, February 2007, summer 2006 etc all my ETF's without me selling.
Some of them were down 15 % last week only to recover where I am only down 5 % this week even with Monday-Tuesday sell-off.
I learned never to panic , wait for market to come back(it always does) and buy when most people run for the exits.
I don't know what happens short term but long term I feel market is going much higher.
I am in my mid 40's and I have time to wait.
Market will always be their.
You can buy 10 ETF's and they all can go down 8 % within a week.
You panic sell and then in 2 weeks storm clears and the ETF's have come back.
Remember why you bought the ETF in the first place and don't let the short term trading alter your decision.
This has worked very well for me.
Just my 2 cents.
