When are stocks vulnerable to correction

Yesterday I said solar energy sector and fertiliser sector stocks are vulnerable to correction at these level. Similarly I had warned about shipping sector before it topped. One of the easiest way to figure out which stock is vulnerable to correction is to look at "Price vs 200 Moving Average" . When the stock is up 100% or more from 200 moving average (which on Telechart sort means value of 200 plus) , it is vulnerable to correction.

IBD studis of top performing stocks show that they top at around 110% from the 200 day MA. From time to time IBD talks about this sell rule.

If you sort the All Stocks list by "Price vs 200 Moving Average" , you will notice most of the stocks with 190 plus readings are solar and fertiliser stocks.

Another thing which signals likelihood of correction in a stock is climax move. Moves of 50% plus in a month on a stock which already has been rallying, typically lead to correction in the stock in next small time frame.
