BRT is more of an investment company than a pure active profit generating company - thus the valuations are difficult to do but it is a classic case of the sum of the parts being worth more than the current share price. If you value their underlying investments (ie Fisheries, Insurance and all BEE holdings such as MTN, LHC, OML, Nedbanck etc) then must try and get into this share. Due to the nature of investments - it may take a while to unlock value but if prepared to wait - then can reap the rewards.
I am holding LHC basically due to my holding in BRN and BRT 0 but with NHI and CC investigating - there are concerns but would prefer LHC but will wait for the uncertainties to be removed. As for the insurers - i am in OML and MMI and belive both will run - again if you hold BRN or BRT you would have some exposure to OML.
