what's going on?, page-16

I follow both BDR and NST fairly closely (own both).
Interesting that according to Westpac Broking data they are very similar in any ways, eg:
Mkt cap BDR $629m NST $517m
Beta BDR .85 NST .80
Earnings stab BDR 69% NST 75%
Est div 2014: BDR 4.8c NST 3.5c, 2015 BDR 3.4c NST 3.5c
DEBT/EQUITY BDR 408% NST 10.2%

Perhaps the last item could be the (current and hopefuly temporary) reason for the recent marked difference in sp between the two, after tracking closely for a while recently? (IMO country risk vs Aust labour/tax/other costs are arguably balanced in these two cases....)
