Taiwan stock market dividend yield distribution

Per-ticker snapshot values, with nothing borrowed across days

Every input is the value that was available on the snapshot date itself, so the decile boundaries are the ones that were genuinely computable that day rather than a recomputation using today's data. This is the site-wide point-in-time rule applied to a cross-section.

Meaningless observations are dropped, and the drop is disclosed

P/E and P/B include only readings above zero. A value at or below zero means a trailing-four-quarter loss or negative book value — that is not the cheapest bucket, it is the ratio losing its meaning. Including them would turn the bottom decile into a bin of loss-makers and pull every boundary down. The excluded count is stated in the coverage note.

Zero yields are kept, not discarded

A cash dividend yield of zero is an observation: the company paid nothing for the period. That is a fact, not a gap. Dropping the zeros would lift the median yield and describe a market that does not exist. Only tickers with no disclosure at all count as missing.

Linear interpolation, and nothing published below fifty observations

Percentiles are taken by linear interpolation over the sorted sample, matching the default method in common statistical packages, so the figures can be recomputed independently. Below fifty valid observations the metric is not published at all — deciles of a small sample describe coincidence, not market structure.
