it's just a rule, it ain't a guarantee. That's why stop rules always apply.

Not sure here Abe.  Where are you in @...

@ I - Right, it is just a rule.  CAN SLIM 101 might say - enter ORCL on  9/16/87 with the 71% inrease in volume Then after it runs 20% in less than 3 weeks, plan to hold for 8 weeks. Exit  after 5 weeks as the stock broke hard through it's it's 50 dma on 10/1987 with a small loss.

CAN SLIM 102 might say avoid the stock altogether because the handle is 15% deep - more than the 1-12% advised.

Advanced CAN SLIM might say "Hey there is a big September rally and we need to be a part of that" - lets make buy 1 on 9/16/1987 even with a deep handle, because the 275,000 share rally is bigger volume than any sell off in the last 8 weeks - add buy 2 on  9/23 with follow on accumulation and pocket pivot volume, add buy 3 at the the new high on 9/25 with "even greater volume".  Plan to hold for 8 weeks due to the 20% rally.  Spot the the Railroad track nature of all the way up and all the way down on 10/6.  Then sell on a 2nd component of weakness within 1 week as the stock closes below the 10 day on 10/9/1987.  Walk away with 17.4% gain.

I stumbled onto this search for 20% up, hold for 8 weeks. We're talking about the biggest market crash in history. It's probably not a fair analysis of the situation.
