Extended explanation
In practice, Gamma refers to rate of change of delta. The exact application depends on context — the country, the type of account or contract, and, where applicable, the tax year or accounting framework. Because the term shows up across contracts, filings, and everyday reporting, understanding both the definition and where it appears is more useful than memorising it in isolation.
Why it matters
Derivatives compress complex payoffs into short names. Understanding the vocabulary is a prerequisite for evaluating risk before entering a position.
Where you'll see it
You'll most often encounter Gamma in research reports, brokerage statements, and product prospectuses. Look up the term in the specific document you're reading, since providers occasionally use slightly different conventions.
