Weekly market wrap — 11 to 15 May 2026
It's not often you read a market report where the All-Share Index rose more than 2% in a week and the NSE 20 fell. This was one of those weeks. The reason it happened — and what it tells you about how to read Kenyan equities — is worth a few minutes of your time, whether you own a single share or run a CDS account that pays your school fees.
One stock did almost all the work
The dominant story of the week of 11 to 15 May was Safaricom. The company published its FY2026 results, and the numbers were the kind that make analyst desks recalibrate models. Attributable profit of KES 95.61 billion. A final dividend declaration of KES 80.13 billion — the largest single corporate dividend ever announced by a Kenyan-listed company. The stock responded by rallying 8.42% on the week and dragging the NASI up with it.
That last part is the lesson. The NASI is a market-capitalisation-weighted index, which means a stock's influence on it is proportional to how big the company is. Safaricom is roughly 30% of the NASI's total weight on its own. When a company that big rallies 8%, you don't have to do much arithmetic to see how the headline index ends up green for the week. By close of business Friday, the NASI sat at 209.65, up 2.10% week-on-week, with total market capitalisation rising to KES 3.477 trillion.
Why the NSE 20 told a different story
The NSE 20 is a different beast. It tracks twenty large, liquid blue chips and weights them very differently from the NASI. In particular, the NSE 20 carries a heavier exposure to Kenya's banking sector — and Kenyan banks had a rough week.
The Banking sub-index lost 1.74% across the five sessions. ABSA Kenya fell 7.87%. Co-operative Bank gave up 6.07%. Even names that didn't make the bottom-five lost ground quietly. The result: the NSE 20 closed the week at around 3,525, down 0.42% on the week, sitting roughly 234 points below its 52-week high.
That gap between the NASI and the Banking Index — two and a half percentage points in five days — is the widest divergence we've seen in 2026 so far. It is not, by itself, an alarming signal. But it does tell you something important about who is buying what. Pension funds and local institutional investors were almost certainly piling into Safaricom to capture the dividend. Foreign investors, meanwhile, were doing something different.
The foreign flow story
Look at one statistic and it gets sharper. Foreigners were net sellers to the tune of KES 751.19 million for the week, and they accounted for over 40% of total turnover. On a week where the headline index rose, foreigners chose to take money off the table.
This is the thread to pull. Foreign selling on a rallying market often means the rally is being held up by domestic flows alone — and domestic flows, in Kenya, can be lumpy and event-driven (a dividend ex-date, a pension fund rebalance, a fund manager taking profits). If foreign selling continues into next week without a corresponding domestic catalyst to replace it, the rally is more fragile than the index level implies.
It's also worth noting what foreigners were selling. The sector mix of the week's turnover was telling: banking accounted for 61.23% of value traded, telecoms (largely Safaricom) accounted for 27.42%, and everything else split the remaining 11%. In other words, the foreign selling was concentrated in the banks they had been overweight, and the local buying was concentrated in the Safaricom dividend trade.
Winners and losers worth knowing
