Mmm interesting. Both are good companies to have in yr portfolio.
While the recent SML SP chart may look better from a TA perspective, when you compare 2yr historical SP performance as per the following chart, ATM has performed about 350% better than SML
Attachment 9789
What will happen in the future?
IMO SML's potential is more capital intensive and tied to its NZ production facilities. By comparison, ATM's less capital intensive potential is tied to multiple production facilities in NZ, AUS, UK, and USA with the benefits of any Frontera production as yet untapped. ATM seems to be disrupting traditional diary production/marketing methods.
Which share will perform best in the longer term? It's going to be interesting to see.
