Sources and evidence
Sources are shown with the role they play in this guide. Historical or style-sensitive claims are kept within the evidence boundary described above.
A “bull market” is a period in which share prices or financial investments are generally rising. The term describes a broad market condition; do not use it for a single asset rising briefly or claim a universal numeric threshold from this dictionary definition.
A “buyer’s market” is a market where supply exceeds buyer demand, typically giving buyers more bargaining power and keeping prices lower. It can apply in housing and other markets; the phrase describes the balance between supply and demand rather than guaranteeing a particular price outcome.
An “economic moat” is a durable competitive advantage that helps protect a company from rivals over an extended period. Morningstar also uses formal moat ratings with its own methodology; do not treat every casual claim that a business has a moat as equivalent to a specific Morningstar rating.
In corporate finance, a “poison pill” is a defensive measure a company uses to make a hostile takeover less attractive or harder to complete. The guide treats it as a specialized current business term rather than inventing an origin story.
A “race to the bottom” describes competitive pressure that pushes participants toward ever-lower costs or standards. The guide keeps current meaning separate from unsupported origin claims.
A “seller’s market” is a market where demand exceeds available supply, typically allowing sellers to charge more or sell more easily. The phrase describes an imbalance favoring sellers; it does not guarantee that every seller or item will achieve a higher price.
Regulation NMS defines best available displayed price by comparing the national best quote with the best disseminated odd-lot order on the relevant side, with a timing rule for midpoint-or-better limit orders. This is a U.S. Regulation NMS term with side- and timing-specific conditions; do not reduce it to a generic synonym for the best visible market price.
Executed Outside the Best Available Displayed Price is a current Regulation NMS defined term. This guide preserves the rule-specific benchmark and direction instead of replacing it with informal trading shorthand.
