Here are some charts looking at how KLCI perform during the correction phase.
Usually I consider a valid correction phase as price violates both trendline and the 20 day MA. Hence from the chart below we see once these 2 lines are violated, the correction phase will last  9 - 47 trading days or 2 - 9 wks depending on how bearish it was.

From the findings:
2009 - no major correction as just emerged from major bear trend in 2008
2010 - 2 times
2011 - 2 times
2012 - 3 times
2013 - so far 1 time
