How to read a market-cap sector breakdown (and its blind spots)
Sector-weight charts are a useful first glance at a market — as long as you remember what they leave out.
Pulsights' Markets page includes a sector breakdown showing how the Tracked-20 composite's combined market capitalization splits across banking, telecoms, industrials and the rest. It's a useful first-glance tool, with a few caveats worth keeping in mind.
What it shows well
Market-cap weighting is a reasonable proxy for which sectors currently command the most investor capital among the tracked names, and shifts in sector share over time can reflect either price performance or new listings/delistings changing the composition.
What it can't tell you
A sector's large weight doesn't mean every company in it is performing well — a single mega-cap name can dominate a sector's total market cap while smaller peers in the same sector tell a very different story. It's a composition view, not a performance view; pair it with the gainers/losers table for that.
A note on the Tracked-20 composite itself
Pulsights tracks 20 NGX-listed companies — a meaningful but partial slice of the exchange's full list of 150+ listed companies. The Tracked-20 composite is an equal-weighted average of those 20, not the official NGX All-Share Index, and the two will diverge. We label this clearly rather than imply otherwise.
