When is the gross profit method acceptable for inventory estimation?
Estimated COGS = Sales x (1 - GP%); Ending Inventory = Goods Available - Est COGS. Keystone's $616K estimate supports the insurance claim. Acceptable for interim and casualty loss scenarios but not annual audited statements.
What is look-ahead bias in backtesting?
Look-ahead uses data unavailable at trade time. Fenwick Strategies' 18% return drops to 11% after applying 75-day earnings lag and point-in-time data.
What is the 'growth of growth rates' concept and why does it matter for terminal value?
Terminal value sensitivity to g accelerates as g nears r — the convex relationship means small terminal-g revisions create outsized valuation swings.
How do I interpret and improve Days Inventory Outstanding?
Days Inventory Outstanding measures how many days of sales a company's inventory represents. Rising DIO without proportionate demand growth is usually a warning sign.
How does buyer concentration affect industry attractiveness?
Buyer power scales with concentration, volumes, standardization, low switching costs, and backward integration threat — reducing supplier margins.
How does multiperiod portfolio choice differ from single-period mean-variance optimization?

How does a 130/30 long-short equity strategy enhance returns vs long-only?

What are 'cookie jar reserves' in earnings management, and how can an analyst detect them?
Cookie jar reserves involve overstating provisions during strong years and releasing excess reserves during weak years to smooth earnings. Analysts can detect them by comparing provision ratios to peers, tracking provision volatility against credit metrics, and watching for sudden reversals.
What are the most common debt covenants, and how do accounting choices affect covenant compliance?
Common debt covenants include minimum interest coverage, maximum debt-to-equity, minimum current ratio, and maximum debt-to-EBITDA. Companies approaching violations may use aggressive accounting -- capitalizing costs, changing depreciation methods, or recognizing revenue earlier -- to improve reported ratios.
What is the financial reporting quality spectrum and how do analysts use it?
The financial reporting quality spectrum ranges from conservative (biased low) through neutral, aggressive (biased high), non-compliant, to fraudulent. Analysts use quantitative tools like the Beneish M-Score, accrual analysis, and peer comparisons alongside qualitative factors like footnote analysis and auditor reports to position companies along this spectrum.
How does the effective interest method work for bond amortization?
The effective interest method calculates interest expense as the bond's carrying value multiplied by the market rate at issuance. For discount bonds, interest expense exceeds the coupon, and the difference amortizes the discount upward toward par. For premium bonds, the coupon exceeds interest expense, amortizing the premium downward.
What can and can't a firm say in advertisements under GIPS advertising guidelines?
The GIPS Advertising Guidelines allow firms to reference their GIPS compliance in marketing materials without presenting the full compliant performance report. However, there are strict requirements about what must be included and what is prohibited.
What is the square root law of market impact and how is it used?
Square-root law: impact scales with sqrt(Q/ADV) times volatility. Used for pre-trade cost estimates, capacity analysis, and order scheduling across asset classes.
What are the components of market impact cost?
Market impact splits into permanent impact (information-based, sticky) and temporary impact (liquidity cost, reverts). Size, volatility, urgency, and info content drive magnitude.
How do I calculate unilateral CVA for a derivative?
Unilateral CVA assumes only the counterparty can default. The formula is UCVA = LGD × Σ[EE(ti) × PD(ti-1, ti) × DF(ti)]. Example: Calder Financial enters a 3-year interest rate swap with Northbridge Corp...
