The NSE 20-Share Index slipped 1.03% on Monday while the broader market eked out a slim gain, leaving the session split between heavy-cap banking weakness and resilience further down the board.
The NSE 20 closed at 3,488.27, off 36.43 points. The NSE All Share Index (NASI) finished at 205.77, up 0.17 points (+0.08%). Market capitalisation actually rose by KES 2.85 billion to KES 3,412.64 billion — confirming the day's split tape: large-cap banks dragged the headline index while breadth across the rest of the listings stayed positive.
Activity stayed solid. Equity turnover came in at KES 196.39 million across 9,511 deals on 12.03 million shares traded. Deal count climbed from the prior session even as volume thinned, pointing to smaller average tickets and broader participation rather than block-driven trade.
The banking sector index lost 2.80 points to 234.05, with Stanbic Holdings (-6.03%) leading the large-cap weakness. Eaagads (-6.13%) and Uchumi Supermarket (-5.20%) rounded out the bottom three.
On the upside, Umeme (+7.65%) topped the gainers, followed by Longhorn Publishers (+6.01%) and Sasini Tea & Coffee (+4.04%). Mid- and small-caps did the day's lifting.
Volume concentrated in financials and utilities: Kenya Re-Insurance led at 4.87 million shares, ahead of Absa Bank Kenya (1.35M) and Kenya Power & Lighting (1.33M).
Takeaway: Index optics hid a two-track day. The NSE 20 still sits about 7% below its 52-week high of 3,758.73 yet holds an 11.12% YTD gain — Monday's drop looks more like name-specific bank selling than a broad risk-off rotation.
