How to use this archive

Follow the source

Events and descriptions are reported by The Zen of Investing. Coverage is not exhaustive. Historical tickers and transaction plans may change; the listed timing and links should be checked against current filings. Some rows describe partial separations or spin-mergers. Inclusion alone says nothing about investment merit.
