How to think about finance questions
The finance problems here run on two unbreakable rules: money has a time value, and you can't make a riskless profit from nothing. Almost every question is one of those two principles applied until a price or a rate falls out.
DISCOUNT EVERYTHING
A dollar later is worth less than a dollar now, so every cash flow gets pulled back to the present at the appropriate rate before you compare anything. Bond prices, project NPVs, and fair forwards are all the same discounted-sum machine pointed at different cash flows.
NO FREE LUNCH
If two portfolios deliver the same future payoff they must cost the same today — otherwise you'd short the dear one, buy the cheap one, and pocket a riskless arbitrage. This single constraint fixes forward prices, put–call parity, and the risk-return trade-off that underpins the rest.
Work this set and two reflexes form: discount the cash flows, and ask whether any price gap lets you lock in a riskless dollar.
