I blame the Abbott Precipitous decline on it's CEO as well as other top echelon people. We who have nothing else in our 401K other than Abbott stock which we have accumulated over so many years, are losing our shirt because of the jerks at the top; damn you pieces of garbage for ruining our future. Get you acts together and fix the problem.
Probably many started diversifying after the Enron debacle. The performance of the laggard didn't help either. Before that most peons were concentrating on the company stock, especialy through the roaring nineties.
DODIX is a good fund, up 12% YTD.
I just posted the link to the guide in my reply to Kiki.
According to the book, Abbott matches 5% of salary for a minimum of 2% contribution (that's 250% match - damn, that's good!) The match goes to the same investments as those chosen for the employees money.
I'm not a participant either. Guess you'll need to find someone who can carry out your query. By the way, the Abbott 401K plan has no only four Putnam funds -- the other 9 are Vanguard, Dodge and Cox, and American Funds. You can find the prospectus online -- publicly viewable - at https://literature.putnam.com/dc_literature/pdf/224490_Abbott_G2.pdf
My colleagues who are in the plan tell me that they average less than 25% ABT, and many they know keep ABT below 10%, especially as they approach retirement age.
