The Nairobi Securities Exchange (NSE) All Share Index, which tracks all stocks listed and market cap weighted, is having its strongest year since its inception in 2008, lifted by record index gains, expanded market capitalization, and renewed foreign investor flows.

Foreign investors returned strongly in August. After a July outflow of KSh 524.1 million, August posted a net inflow of KSh 1.65 billion—the highest monthly inflow since August 2021.

The rebound included KSh 393 million in the last two trading days, reinforcing bullish momentum.

The combination of record-breaking index gains, broad-based stock rallies, and the return of foreign inflows signals a rare upcycle for the NSE, last seen in the early 2010s.

The rally has been wide, with ten stocks more than doubling in 2025. Sameer Africa has surged +576.95%, while Home Afrika (+210.81%), Kenya Power (+196.26%), TransCentury (+187.18%), and Kenya Reinsurance (+182.81%) also feature among the top movers.

Express Kenya, CIC Insurance, HF Group, KenGen, and NSE PLC round out the list of counters above 100%.

Seven stocks remain negative this year. Umeme leads the losers at -43.04%, followed by Nairobi Business Ventures (-19.90%) and Bamburi Cement (-14.18%). Limuru Tea, Nation Media, Kenya Airways, and Africa Mega Agricorp are also in the red.
