What about the 8 week rule (if stock is up 20% or more in less than 3 weeks you must hold for 8 weeks)

I figure that the 8 week hold rule is for tip top stocks with great earnings and sales growth with strong projections, coming out of first and second stage bases.

TWTR seems to me to be a real brand new game changer in the info-entertainment world.  Lots of revenue and subscriber growth and connections with legacy media, politics and entertainment, so I really want to be a part of this new media.  Now a few months later it is clear that TWTR needed to work through some issues.  Similar to FB during it's first six months.  

CAN SLIM says that we should wait for a 30% rally and then a base.  Then we can assess the base to see if the institutional interest is really there.  As of today TWTR has rallied 21% from the low and the accumulation has been good.
