How are these peers chosen?

Peers are every company that BQ-MICS, our own multi-industry classification system, places in the same industry group as Biolargo, Inc.. Unlike a single-label scheme, BQ-MICS assigns each company a primary industry and any secondary industries it genuinely operates in, and records the reasoning behind every assignment. Tap the info icon beside any ticker to read it.

What does "2nd" next to a ticker mean?

It marks a secondary match: the company operates a real business in this industry group, but it is not its largest. Tick "Primary business only" above the table to compare against pure plays alone.

How often is this peer comparison updated?

Prices, market caps and valuation figures refresh with each session's close. The classification itself is reviewed whenever a company's filings change what it does, such as a new segment, a disposal or an acquisition.
