I have done some analysis on Renuka Group companies (COCO, RHL and RAL).
Please refer the link into research section :
http://research.srilankaequity.com/t352-valuations-of-renuka-group#405
* Renuka group is mainly export driven and hence sustainable in local inflation conditions.
* They will benefit immensely from Rupee depreciation.
* Asset valuations are due in 2012.
* Shares are bit difficult to collect, but prevailing conditions might provide some opportunities.
***** Open for discussion *****
