300 resultsPrice-to-Book Ratio
P/BQuick Definition
The price-to-book ratio compares a company's market value with its accounting book value.
Full Definition
P/B can be calculated as share price divided by book value per share, or market capitalization divided by common equity. It can help compare asset-heavy companies, but it may be less informative when book values are outdated, negative, or omit important intangible assets.
Example
A stock at $30 with book value of $15 per share has a P/B ratio of 2.
Also Known As
Price-to-Earnings Ratio
P/EQuick Definition
The price-to-earnings ratio compares a stock's market price with its earnings per share.
Full Definition
P/E is calculated by dividing price per share by EPS and shows how much the market pays for one unit of reported earnings. Comparisons are usually most useful among similar companies and periods, because growth, risk, accounting, and one-time items can make ratios differ.
Example
A $100 stock with $5 of annual EPS has a P/E ratio of 20.
Also Known As
Primary Market
Quick Definition
The primary market is where newly issued securities are first sold and the issuer receives the proceeds.
Full Definition
Companies and governments use the primary market to raise new capital by issuing stocks or bonds. This differs from secondary-market trading, where investors trade already-issued securities with one another.
Example
Shares sold by a company during its initial public offering are sold in the primary market.
Also Known As
Private Key
Quick Definition
A private key is a secret cryptographic value that authorizes control of a blockchain account or its assets.
Full Definition
Wallet software uses the private key to create valid digital signatures for transactions. Anyone who obtains it may be able to move the associated assets, and a blockchain usually has no password-reset desk. It should never be shared or entered into an untrusted site.
Example
The attacker stole the private key and signed a transfer to a different address.
Also Known As
Producer Price Index
PPIQuick Definition
The Producer Price Index measures average changes in selling prices received by domestic producers.
Full Definition
PPI tracks price movements from the producer side of the economy rather than the prices consumers pay. It can cover goods, services, construction, and different stages of demand depending on the published series. Traders watch it for evidence of cost pressure that may later affect consumer prices or company margins.
Example
A sharp increase in PPI may suggest that producers are facing higher input or selling prices.
Also Known As
Profit and Loss
P&LQuick Definition
Profit and loss is the net financial result after gains and income are compared with losses, costs, and expenses.
Full Definition
For a trading account, P&L may combine realized results from closed positions with unrealized changes in open positions. The reporting period, fees, financing costs, dividends, taxes, and valuation method can all affect the number shown.
Example
A $500 trading gain minus $80 of fees and losses produces net P&L of $420.
Also Known As
Proof of Stake
PoSQuick Definition
Proof of stake is a consensus method that uses staked assets and validator incentives to secure a blockchain.
Full Definition
Validators lock or commit value and are selected under protocol rules to propose or confirm blocks. Honest participation can earn rewards, while inactivity or serious rule-breaking may cause penalties. Proof-of-stake designs differ, so their security assumptions and staking rules are not identical.
Example
Ethereum validators stake ETH and attest to blocks under its proof-of-stake rules.
Also Known As
Proof of Work
PoWQuick Definition
Proof of work is a consensus method in which miners spend computing effort to compete for the right to add a block.
Full Definition
Miners repeatedly hash candidate block data until one finds a result that meets the network's difficulty target. Other nodes can verify the work quickly and follow the valid chain selected by the protocol. Attacking a mature proof-of-work network generally requires substantial computing power and energy.
Example
Bitcoin miners use proof of work to compete to publish the next valid block.
Also Known As
Protective Put
Quick Definition
A protective put combines ownership of an underlying asset with the purchase of a put option to limit downside risk.
Full Definition
The put gives the investor the right to sell at the strike, creating a floor for the covered holding during the option's life. The protection costs the premium and can expire unused. Loss below the strike is limited for the matched quantity, but the position can still lose the amount between the purchase price and strike plus the premium and costs.
Example
An investor holding shares at 100 buys a 90-strike put to protect against a large decline before expiration.
Also Known As
Public Key
Quick Definition
A public key is the shareable part of a cryptographic key pair used to verify digital signatures.
Full Definition
A private key creates a signature, and the matching public key lets others verify that signature without learning the secret. Blockchain addresses are often derived from public keys, although the exact method varies by network. A public key should not be confused with the private key that authorizes spending.
Example
The network used the public key to verify that the transaction signature was valid.
Also Known As
Pullback
Quick Definition
A pullback is a temporary price move against the direction of a broader trend.
Full Definition
In an uptrend it usually means a short decline from a recent high, while in a downtrend the opposite move may be called a bounce or countertrend rally. A pullback can develop into a full reversal, and the difference is clear only with later price action.
Example
A stock rising from $40 to $50 and then slipping to $47 before resuming higher has experienced a pullback.
Also Known As
Purchasing Managers' Index
PMIQuick Definition
A Purchasing Managers' Index summarizes survey responses from business purchasing managers about whether activity is improving, unchanged, or worsening.
Full Definition
PMIs can cover manufacturing, services, construction, or the combined private sector. A headline diffusion index above 50 commonly signals expansion from the previous month, while below 50 signals contraction, but it does not measure the exact growth rate. Methodology and coverage depend on the survey provider.
Example
A manufacturing PMI of 53 generally indicates that more survey evidence points to monthly improvement than deterioration.
Also Known As
Put Option
PutQuick Definition
A put option gives the holder the right to sell the underlying interest at the strike price under the contract's terms.
Full Definition
A put buyer may use the contract to seek profit from a decline or to protect an existing holding. The put writer receives the premium but may be required to buy or cash-settle the underlying exposure if assigned. The buyer's expiration payoff depends on how far the underlying price is below the strike, less the premium and costs.
Example
An investor buys a put on a stock index to reduce the damage from a large market decline.
Also Known As
Quantitative Easing
QEQuick Definition
Quantitative easing is a monetary-policy program in which a central bank buys financial assets to ease broader financial conditions.
Full Definition
QE is often used when short-term policy rates are very low or when market functioning needs support. Purchases increase central-bank asset holdings and typically add reserves to the banking system, with the aim of lowering longer-term yields or supporting credit conditions. Its effects depend on expectations, asset choice, scale, and economic circumstances.
Example
A central bank buys government bonds each month to put downward pressure on longer-term borrowing costs.
Also Known As
Quantitative Tightening
QTQuick Definition
Quantitative tightening is a monetary-policy process that reduces a central bank's asset holdings and usually withdraws reserves from the banking system.
Full Definition
The central bank may allow securities to mature without full reinvestment or may sell assets under a stated plan. QT can tighten financial conditions and affect market liquidity, although its impact is not simply the exact opposite of QE. The pace, reserve level, and communication surrounding the program matter.
Example
The central bank caps the amount of maturing bonds it replaces, causing its balance sheet to shrink gradually.
Also Known As
Quote Currency
Quick Definition
The quote currency is the second currency shown in a currency pair.
Full Definition
The quote currency is the currency used to express the price of one unit of the base currency. In EUR/USD, USD is the quote currency. Selling the pair normally means selling the base currency and buying the quote currency.
Example
In AUD/USD, the US dollar is the quote currency.
Also Known As
Rally
Quick Definition
A rally is a sustained or sharp rise in the price of a security, market, or asset class.
Full Definition
A rally can occur during an uptrend or as a temporary recovery within a bear market. The term describes past price action and does not prove that a new long-term bull market has begun.
Example
An index rising 8% over two weeks after a selloff is experiencing a market rally.
Also Known As
Realized Profit and Loss
Realized P&LQuick Definition
Realized profit and loss is the gain or loss recognized when all or part of a position is closed or disposed of.
Full Definition
It is generally based on the sale proceeds compared with the assigned cost basis, adjusted for applicable costs. The precise accounting and tax result can depend on which purchase lot is treated as sold and on local rules.
Example
Buying a share for $40 and selling it for $50 realizes a $10 gain before fees and taxes.
Also Known As
Recession
Quick Definition
A recession is a broad and meaningful decline in economic activity that lasts beyond a very brief period.
Full Definition
Analysts examine measures such as real output, income, employment, production, and sales to judge recessions. Two consecutive quarters of falling real GDP is a popular rule of thumb, but it is not a universal official definition. Dating methods and declarations differ across countries and institutions.
Example
Falling production, employment, income, and spending across several months can indicate a recession even before final GDP data are available.
Also Known As
Relative Strength Index
RSIQuick Definition
The Relative Strength Index is a momentum oscillator that compares the size of recent gains with recent losses on a 0-to-100 scale.
Full Definition
Traders commonly describe readings above 70 as overbought and below 30 as oversold, but these are conventions rather than automatic trading signals. RSI can remain at an extreme during a strong trend, so it is usually considered with price action, trend, and risk controls.
Example
An RSI reading of 75 shows strong recent upward momentum but does not guarantee that the price will fall next.
Also Known As
Resistance
Quick Definition
Resistance is a chart area where selling has previously been strong enough to slow or reverse a price rise.
Full Definition
Technical traders look for resistance near earlier highs, trend lines, moving averages, or other price patterns. Resistance is not a guaranteed ceiling, and a decisive move above it is often called a breakout.
Example
If a stock has failed several times near $60, traders may watch $60 as a resistance area.
Also Known As
Retail Sales
Quick Definition
Retail sales measure sales by retail and food-service businesses over a stated period.
Full Definition
The release is used as a timely indicator of consumer spending on goods, although it does not cover all household services. Headline values are commonly reported in current money terms and can be influenced by both price and quantity changes. Traders also examine category details, revisions, and measures excluding volatile sectors.
Example
A 0.8 percent monthly rise in retail sales means reported sales value increased from the previous month before later revisions.
Also Known As
Return on Equity
ROEQuick Definition
Return on equity measures net income relative to shareholders' equity.
Full Definition
ROE is commonly calculated by dividing net income by average shareholders' equity for the period. It can help compare profitability among similar companies, but heavy debt, share buybacks, or very small equity can make the ratio look unusually high.
Example
Net income of $15 million on average equity of $100 million produces a 15% ROE.
Also Known As
Return on Investment
ROIQuick Definition
Return on investment compares an investment's net gain or loss with the amount invested.
Full Definition
A simple ROI is calculated as net result divided by initial investment, usually expressed as a percentage. It is easy to understand but does not by itself account for how long the investment was held, the timing of cash flows, or the risk taken.
Example
A $200 gain on a $2,000 investment is a 10% simple ROI.
Also Known As
Revenue
Quick Definition
Revenue is the money a company earns from selling goods or services before expenses are deducted.
Full Definition
Revenue appears near the top of the income statement and is often called the top line. Growth in revenue can show expanding activity, but investors must also examine costs, profitability, cash collection, and the accounting policies used to recognize sales.
Example
A company that sells 100,000 subscriptions at $10 each records $1 million of revenue before related expenses.
Also Known As
Risk Management
Quick Definition
Risk management is the process of identifying, measuring, and controlling the chance and size of investment losses.
Full Definition
It can involve diversification, position limits, liquidity planning, hedging, exit rules, and matching investments to time horizon and loss capacity. Risk management cannot remove uncertainty, but it can reduce the damage from an adverse event or a wrong decision.
Example
A trader limits each position to 2% of the portfolio so one loss cannot dominate the account.
Also Known As
Risk-Reward Ratio
R:RQuick Definition
The risk-reward ratio compares a trade's planned loss with its planned gain.
Full Definition
A trade risking 1 to seek 3 has a risk-to-reward ratio of 1:3. The ratio should be considered with the probability of winning, trading costs, slippage, and how consistently exits are followed. An attractive target ratio alone does not make a strategy profitable.
Example
Buying at 100 with a stop at 98 and target at 106 plans 2 of risk for 6 of reward, or 1:3.
Also Known As
Roll Yield
Quick Definition
Roll yield is the part of a futures-based return associated with replacing an expiring contract with a later contract and with prices converging over time.
Full Definition
A long position may face negative roll yield when it sells a cheaper nearby contract and buys a more expensive later contract in contango. It may receive positive roll yield when the later contract is cheaper in backwardation, all else equal. Actual results also depend on when the roll occurs, how the curve moves, transaction costs, and the spot-price change.
Example
A fund sells a nearby future at 70 and buys the next contract at 72, creating a 2-unit roll cost before later price changes.
Also Known As
Rollup
Quick Definition
A rollup is a scaling system that executes many transactions away from a base blockchain and posts compressed data or proofs back to it.
Full Definition
Optimistic rollups assume batches are valid unless successfully challenged, while zero-knowledge rollups submit validity proofs. By sharing settlement or data with the base layer, rollups can reduce fees and increase throughput. Security also depends on factors such as data availability, proof systems, upgrade keys, sequencers, and withdrawal mechanisms.
Example
The rollup combined hundreds of user transactions into one batch submitted to Ethereum.
Also Known As
Rug Pull
Quick Definition
A rug pull is a crypto scam or abusive exit in which project insiders remove value or abandon a project after attracting users' funds.
Full Definition
Operators may drain liquidity, mint and sell hidden tokens, misuse privileged contract controls, or simply disappear with funds. Some failures are poor management rather than deliberate rug pulls, so evidence matters before using the label. Anonymous teams, concentrated ownership, unlocked liquidity, and unaudited admin powers can increase risk but do not prove fraud by themselves.
Example
The developer withdrew nearly all pool liquidity and buyers could no longer sell, which was described as a rug pull.
