Probably. They are not "marginal" billionaires. Plus they have other interests not just the NSE.

Amin Juma, arguably the wealthiest among Kenya’s stock market investors, for instance earned Sh130 million from his stakes in Nation Media Group (NMG) and Diamond Trust Bank for the year ended December 2012. The businessman has 15.6 million shares in NMG and two million shares in DTB worth Sh5 billion. People familiar with Mr Juma’s investment activities say he has since settled on publicly quoted equities as his key asset class. His 8.1 per cent stake in NMG is the second largest after the Aga Khan Fund for Economic Development’s (Akfed) at 44.6 per cent.

His DTB stake is way more than 1bn even in this market. The rest are condiments to enhance his wealth.

John Kibunga Kimani, another stock market mogul, holds more than a million shares in most of the NSE’s blue chips with a total equities portfolio of more than Sh2 billion. His 2.7 million shares in EABL is worth Sh894 million and represents his biggest stock market investment followed by the 2.1 million NMG shares worth Sh636.6 million. Mr Kimani is known to have vast business interests outside the stock market, including transport, construction, and logistics. The businessman, who was brought up in listed agricultural firm Kakuzi’s central Kenya estates, where his father worked, has 4.2 million shares worth Sh336.5 million of the company.

Kakuzi has done well for JKK at 250/- per share so he has 1bn+ just in Kakuzi. Then add the other stakes.

Baloobhai Patel, a director of Pan Africa Insurance, is invariably listed as one of the largest individual shareholders of more than 10 companies on the Nairobi bourse. The 75-year-old has major interests in Pan Africa Insurance, Barclays, Bamburi, DTB, Mumias Sugar, and Safaricom currently valued at Sh2.4 billion. Mr Patel also operates a tour firm Trans-world Safaris where he is the managing director.
Easily worth more than 1bn. Just Carbacid. And if he still has Safaricom then he is laughing all the way to the bank.

Sunil Shah, a former director of KCB, is one such investor with 53.4 million shares in the bank currently valued at Sh2 billion and from which he earned Sh107.3 million in dividends for the year ended December 2012. Regulatory fillings indicate that Mr Shah, who also serves as a director of United Millers Ltd, may be cutting his ownership of KCB.
KCB, properties, etc. I would say 1bn+

Profit taking has started with investors targeting the ksh.25bn 10-year bond which closes on Tuesday 23 August 2016.
Safaricom trading a volume of 19.52mn shares
KCB trades a volume of 11.78mn shares

Sadly money that should be going to the PRODUCTIVE (real not tenderpreneurs) private sector is going to GoK which is on a spending spree.

on 19, 20,21 and 26 july 2016 abnormal volume more than daily average volume

Why write obvious things..

There is a rout coming.
Ngoja next week Wednesday when federal reserve raises interest rates

Safaricom not going above 19 unless they come with an extra ordinary announcement.
There are no buyers above that price

The rise of interest rate means that the $ will raise in value(money will become expensive) the effect of that is, US stocks will be more valuable so there will be capital flight from emerging mkts by foreign investors.
