Omicron reference note

This page belongs to a controlled crawl-diff experiment on PortfolioHQ. It carries ordinary prose so that a crawler measuring overlapping word sequences has something real to compare between two runs.

A portfolio report is only as good as the record behind it. When a holding is entered once and never revisited, the reasoning that justified it fades, and what remains is a number without a rationale. Keeping a short written note against each position costs little at the time and saves a great deal at the next review.

Concentration is the risk that hides most easily. A portfolio can look balanced by count while two or three positions carry most of the value, and sector exposure can drift a long way from where it started without any single decision having felt wrong. Measuring allocation on every refresh is what turns that drift into something visible.

Currency, timing and fees all shape a result that a headline percentage will not show. A gain quoted before costs is not the gain that reached the account, and a figure taken on a single day can flatter or punish a position that has not actually changed. Reports should be read with those caveats in mind.

Read every figure here as a description of one file at one moment, not as a live valuation.
