Low severity#

  • W3 — “### Risk economy with arrow securities” (line 343) — “arrow” should be “Arrow” (proper noun: Arrow securities); minor.

  • W1 — A few two-sentence paragraphs (e.g. lines 113–117).

  • [qe-code-002] — beta = 0.95 (line 327) and subsequent usages use spelled-out beta instead of unicode β. Count: 3 occurrences.
