Saul's trading returns

I've heard the Gardner brothers talk about how their portfolios would have better 
returns if they never sold a position, they talk about 5 year hold periods, etc.  
This made me wonder what Saul's portfolio would look like if he had a similar 
approach.  i.e. Does his trading add to or subtract from his returns.  So I looked 
at this for calendar 2018 (yeah, it's just 1 year, but I have a life!)  I compared 
Saul's 12/31/17 port from his post, using the then actual allocations, to the value 
those same stocks would have yielded if still held in the same proportions at 12/31/18 
(see below).  The result?  An impressive 34.5% return vs the S&P's (6.6%).  But that 
pales in comparison to his actual return for 2018 of 71.4%!  Considering many of the 
2017 names are still held by Saul and others here and that none of these companies blew 
themselves up, this is quite impressive for sure!

I hope this is not too off topic thus posting on a weekend.  I've been following this 
board since May '18 and to me this really validates the concentrated portfolio/highest 
conviction approach followed here.  So what am I doing?  I've reduced my portfolio from 
59 stocks in May to 30 as I write this, although 7 of them are pretty small holdings so 
it's more like 23.  I'll probably knock a few more off before I settle in on a long term 
number I'm comfortable with.  The hard part is having the conviction necessary to have 
10+% positions and I'm not yet sure how I'd feel holding many smaller cap companies if 
a bigger bear hits (though I held up just fine during the recent 20% drop).  So, big 
thanks to all that contribute here!!
