About this question’s source match

Title, subcategory and exact catalogue slug were used in public-source searches. The exercise applies the standard method in a newly authored scenario. The catalogue title does not reveal its inaccessible numerical statement. No hidden Trading Interview statement or solution is claimed recovered. Numbered scenarios do not identify their original setup; all legs and conventions here are explicit. For546 the title/slug orientation conflict is disclosed.

Interpret long put spread as a European debit bear-put spread: buy strike 110 put for 12 and sell strike 100 put for 5, one unit each, same expiry. Report maximum net profit as main answer; give maximum loss, breakeven and P&L at 90,105,120. Explain the title/slug ambiguity.

Assumptions and constraints

  • All prices, probabilities and contract terms are fictional practice inputs.
  • No fees, taxes or financing costs apply except where expressly stated.
  • Use the given horizon, cash-flow timing, compounding and settlement conventions.
  • Give the main numerical result as well as the requested interpretation.

Examples

S 105, long 110 put, short 100 put, debit 7
→ P&L -2

Intrinsic 5 minus debit 7.
