You're definitely doing the right thing to hold. I would only be concern with your portfolio balance. Looks like you have too many - not just financials but banks. You did didn't post the % per counter so it's hard to know if you're over-invested in Financials. I would sell some and get at least one agricultural counter at this time when they are low. I'd propose Kakuzi or Vipingo. I'm working on getting some myself.

@2012...Im also heavily averaging down my holdings in Kakuzi.
@ KakaM....some good advice there from @2012. Diversification also involves diversifying by industry. As it is you have a huge concentration of banks, not bad this season but what about the next, food for thought.
You can put in some money say in Kakuzi, BAT and the very oversold KPLC....Just my opinion.

I hope that the money that KCB intends to put into its subsidiaries will turn them around. Equity's already have.
Kaka M, since you seem to have a fetish for banks, i would suggest KCB:EQUITY 50:50. If you decide to enter other segments, you can consider the examples stated by others

Gatheuzi, I thought you made a killing from being 100 percent in banks a while back

I admire your patience 15-20 years you will still make money but If i was in your position i would try and treat my portfolio like a shamba you have to till, plant, weed it's not a forest where you plant trees and come to harvest after 15-20 years. Try and follow what is happening in the companies you are invested in what are the long-term prospects if you feel they are good companies also follow the price movement and average down your purchase price by buying at a lower price e.g safcom 3.7, KCB 17. It's a stock market(ni soko) so you have to keep checking the prices once in while and pick bargains.
And please avoid those agriculturals unless you know how to value biological assets
