>What is the P/E ratio?
P/E is share price divided by earnings per share. It shows how much investors pay for each unit of current profit.
>What is the P/B ratio?
P/B is market value divided by net assets. It compares stock price to the book value on the balance sheet.
>What is ROE?
ROE is net profit divided by average shareholders' equity. It measures how efficiently a company uses shareholder capital.
>What does market capitalization mean?
Market cap equals share price times total shares outstanding. It is a quick way to size a listed company.
>What is inflation and why does it matter?
Inflation is a broad rise in prices over time. It erodes purchasing power and affects interest rates, valuation, and asset returns.
>What is the difference between nominal and real returns?
Nominal return is your headline gain. Real return is nominal return minus inflation, which reflects true purchasing-power growth.
>What is an index fund?
An index fund tracks a target index by holding a basket of securities. Its goal is to replicate index performance, not beat it.
>What is the difference between ETF and mutual fund?
ETFs trade intraday like stocks, while mutual funds are usually priced once per day. They can track similar strategies with different trading mechanics.
>What is expense ratio?
Expense ratio is the annual management and operating cost charged by a fund as a percentage of assets.
>What is tracking error?
Tracking error measures how far a fund's returns deviate from its benchmark index over time.
>What does diversification mean?
Diversification means spreading investments across assets, sectors, or regions so a single loss does not dominate your portfolio.
>What is dollar-cost averaging?
Dollar-cost averaging means investing a fixed amount regularly. It reduces timing pressure and smooths entry cost across market swings.
>What is the relationship between risk and return?
Higher expected return usually requires taking higher uncertainty. The key is whether the risk is understandable and affordable for you.
>What are the three core financial statements?
Income statement, balance sheet, and cash flow statement. Together they show profitability, financial position, and cash movement.
>What does a balance sheet tell me?
It shows assets, liabilities, and equity at a point in time. It helps you assess leverage, liquidity, and capital structure.
>What does an income statement tell me?
It shows revenue, costs, and profit over a period. It helps you evaluate a company's profitability trend.
>What does a cash flow statement tell me?
It tracks operating, investing, and financing cash flows. It shows whether profits are turning into real cash.
>How are the three statements connected?
Net income flows into equity, and cash changes appear in the cash flow statement then reconcile to balance-sheet cash. They should be consistent.
>What is free cash flow?
Free cash flow is operating cash flow minus capital expenditure. It represents cash that can be used for debt repayment, dividends, or reinvestment.
>What is the difference between gross margin and net margin?
Gross margin focuses on production economics before operating expenses, while net margin includes all costs and taxes to show final profitability.
>Why do accounts receivable and inventory matter?
Fast growth in receivables or inventory can signal weaker demand quality, slower cash conversion, or potential write-down risk.
>What is debt-to-asset ratio?
Debt-to-asset ratio equals total liabilities divided by total assets. It is a basic indicator of leverage and solvency pressure.
>What does goodwill represent on the balance sheet?
Goodwill usually comes from acquisitions when purchase price exceeds identifiable net assets. Large impairments can hurt future earnings.
>Can a company be profitable but still short on cash?
Yes. Profit is accrual-based, while cash flow is timing-based. Slow collections, high inventory, or heavy capex can create a cash squeeze.
