Investment analysis

Investment score 40 / 100

Each component is a percentile rank against every other HDB block in the database. This is an analytical indicator, not financial advice.

40/100

100% of the scoring weight measurable

Every bar is a percentile rank, so 70 means this development sits above roughly 70% of its peers on that factor. Factors we cannot measure are excluded and the remaining weights are rebalanced, rather than scored as zero.
