My own opinion, these are what I call my big 5 (am not a trader, i just buy long term. Plus i disregard insurance stocks since banks can offer the same service to the big boys in the industry)
1. KCB - giant corporate and retail banking in Kenya. Growth in customer deposits is highest in the industry hence higher ability to lend more and make more money. Expansion into outside Kenya hence access to more economies and a larger population in general. This means more business. Their insurance business is growing extremely well.

2. Equity Bank - biggest retail bank in Kenya and the most innovative when it comes to technology and customer focused products. Very good growth in Tanzania and the rest of East Africa. Has plans to venture into 5 more countries in Africa with Nigeria on the list if all goes well. Banking penetration in Africa is still low 25% I think as compared to what we have in developed countries over 80% of adults. This is due to little formal employment that pays through cheques. So lots of room for growth.

3. Kenya Power - it is the only supplier of electricity in Kenya. We consume just 2000Mw while the likes of South Africa have demands of 40,000Mw. If we develop to that extent I think we should hit even 15,000Mw of power demand. That is 7 times the revenue. Currently a cheap share due to lack of high dividends but it will change eventually I believe since they are now doing so much improvements.

4. Safaricom - The telecommunication giant in Kenya. Very innovative and launches new products very early. Smartphone increase revenue per user by as much as 4 times. Currently we have 3.5 million in the network. There is the untapped home internet market plus tv subscription which they may venture into. 4G will bring faster internet and may lead to more consumption since we get things much faster. Mpesa growing trendously and the remittance market from abroad is a new growth sector in mpesa. Having the ability to send money into and out of Kenya would really bring lots of convenience.

5. Centum - has tapped into so many sectors with the latest being energy production. They have a large portfolio of real estate in and out of Kenya. They have a foot into banking through K-Rep bank and growth possibilities is endless. They also have a hold in the bottling business

I bet it's been a hell of a ride for the many who played hio mchezo ya sukari :D
