Cheap vs Expensive Shares in Kenya: What Investors Should Know
TL;DR – Quick Summary
Relying on NASI alone is risky. Market breadth (advancing vs declining shares) and trading volume (actual money behind moves) reveal the true trend. This guide shows how Kenyan investors can interpret these signals using 2025–2026 NSE data, micro-stories, and sector insights.

Many Kenyans ask: “NASI is up, but why are most shares flat or falling?” From what I’ve observed, NASI’s market-cap weighting means large companies like Safaricom, Equity Bank, and KCB dominate the index. For example, on 18 Jan 2026, NASI rose 0.8% while 36 of 66 shares declined. This shows that the market rally was narrow, not broad — a critical signal for trend-spotting.

Market breadth shows the number of shares rising, falling, or unchanged. Spotting trends means comparing NASI moves with breadth:
| Date | Advancing Shares | Declining Shares | Unchanged |
|---|---|---|---|
| 18 Jan 2026 | 18 | 36 | 12 |
| 16 Jan 2026 | 17 | 26 | 15 |
| 14 Jan 2026 | 22 | 30 | 14 |
Observing breadth over several days highlights whether a NASI rally is broad or narrow. Narrow breadth signals caution — the trend may not sustain.
Volume confirms the strength of price movements. On 18 Jan 2026, total turnover was ~KES 3.8 billion, concentrated in Safaricom and Equity Bank. Many mid-cap stocks had low volume, showing that the NASI gain was driven by a few heavyweights rather than broad market participation.
Sector concentration affects trend strength:
Trends are stronger when multiple sectors participate. Narrow sector dominance signals a risky trend — essential for spotting real opportunities.
Mary, a Nairobi teacher, invested KES 50,000/month in 10 mid-cap stocks. NASI rose 2% in January 2026, yet her portfolio fell 1.2%. She learned that **tracking NASI alone hides real performance**. Observing breadth and volume would have revealed the weak trend early.
Past patterns show NASI can rise while advancing shares remain low — typical post-election years, when blue-chip speculation is high. Experts use this to anticipate corrections and identify undervalued mid-caps.

Can NASI rise when most shares fall?
Yes — NASI is weighted by market cap, not by the number of advancing shares.
Is market breadth an official NSE metric?
No, it’s derived from trading data but widely used by analysts.
Does low volume always signal weakness?
Not always, but low volume often shows lower market participation behind NASI moves.
