I suspect any responses you get will be from legacy investors like Maurice and myself. Though unlike Maurice, I did invest in a Columbia fund ages ago, when Columbia was a boutique shop in Oregon with a few good growth funds. Got rid of that in 1997 when
Columbia was acquired by Fleet Boston (later called Fleet Financial).
The Acorn lineage that Maurice is referring to is almost completely separate.
Liberty acquired a bunch of fund companies including
Stein Roe (Young Investors fund, Stein Roe Special), Newport Pacific (Newport Tiger Fund), Wanger (Acorn Funds), and others.
Fleet Boston brought these Liberty lines together with Columbia in 2001 (when it acquired Liberty). BofA in turn acquired the whole mess in 2004, subsequently merging some Nations Bank funds into it. (BofA had merged with Nations Bank previously.)
Regarding Excelsior funds - they were acquired by US Trust (which was acquired at some point by Schwab, but sold to BofA in 2007), and
rebranded Columbia when BofA acquired them.
BofA has since sold the Columbia line to Ameriprise.
The Acorn funds have been kept somewhat separate, but otherwise, I don't have a clue what "Columbia Funds" means anymore. It's certainly not the low cost growth-oriented boutique I bought years ago.
I do know that they make it exceedingly difficult for "eligible investors" (those who are allowed to purchase noload Z shares like SMGIX). Can't seem to open an account online, can't even find an application to download that includes Z class shares.
Columbia has closed off access to Z shares via supermarkets - you can buy their A shares, but Z share accounts are frozen (no buys allowed, even for grandfathered customers).
You put all that together, and maybe Columbia is of interest for hard-to-find types of funds, but it's not a family I'd be looking to for most categories. All that said, Pope seems to be doing a fine job at SMGIX. It's natural that this resembles the current incarnation of UMBIX, since Pope manages that as well (albeit with others there).
But as M* opines, it's a different style now - not the same as the value-oriented fund you sold off. If that's what you're looking for, it seems you may still need to keep looking.
