one thing that irks me about gava firms is handling of rights issues. there's always a push and pull, rumours. announced like 2 yrs before causing share to suffer in open market. look at uchumi, ken gen. nbk. a real major shareholder would never let his shares lose value like this.
also how gava company react to losses. would a gava run firm for example react the way Kenol Kobil reacted to its major 6.2b loss. a major aggressive restructure. and overhaul of management. an almost immediate move.
A gava firm would be slower to react, leading to a situation like Uchumi, kplc and KCB a few years ago.
speculatively yes you will make a lot of profit if u play it right.
long term... it's just a matter of time before they crash the party.
The investor's chief problem - and even his worst enemy - is likely to be himself
