Valuation

IV
Intrinsic Value

An estimate of what a business is genuinely worth, based on the cash it can generate over time — independent of its current share price. If the price sits below intrinsic value, the stock may be undervalued.

DCF
Discounted Cash Flow

A valuation method that estimates intrinsic value by forecasting a company’s future free cash flows and converting them into today’s money. Because cash in the future is worth less than cash now, each year is “discounted” by a rate that reflects risk.

WACC
Weighted Average Cost of Capital

The blended rate of return a company must pay its lenders and shareholders, weighted by how much it uses of each. In a DCF it is the discount rate — a higher WACC (a riskier business) produces a lower intrinsic value.

RV Score
Relative Valuation Score

Oak Growth’s 0–99 score for how cheap or expensive a stock is versus its sector, blending P/E, P/FCF, P/Book and EV/EBITDA against the sector median. A higher score means cheaper relative to peers.

MOS%
Margin of Safety

The gap between a stock’s price and its intrinsic value, shown as a percentage. The wider the discount, the more room you have to be wrong about the future and still invest soundly — the core idea of value investing.

P/E
Price to Earnings Ratio

The share price divided by earnings per share — roughly how many years of current profit you are paying for the business. A high P/E implies the market expects strong growth; a low one implies caution, or value.

Business quality & the Oak Growth screen

Moat
Competitive Moat

A durable advantage — brand, scale, network effects, switching costs or patents — that protects a company’s profits from competitors for years. Wide-moat businesses sustain high returns far longer.

4 Pillars
The Buffett 4-Pillar Screen

The four tests a company must pass to appear in Oak Growth’s screener: Moat, Value, Financials and Management. Only companies that clear all four make the cut.

US Quality
US Quality Screener — why different thresholds

The S&P 500 version of the Buffett screen: the same philosophy, but recalibrated thresholds. Large US companies typically carry higher valuations and different balance-sheet norms than UK or European peers, so identical cut-offs everywhere would unfairly screen them out.

ROE
Return on Equity

Net profit divided by shareholders’ equity — how efficiently a company turns its owners’ money into profit. Consistently high ROE, without leaning on excessive debt, is a hallmark of a quality business.

D/E
Debt to Equity Ratio

Total debt divided by shareholders’ equity — how much a company leans on borrowed money. Lower is generally safer, though the healthy level varies a lot by sector.

FCF
Free Cash Flow

The cash left after a company has paid its running costs and reinvested in itself. It is the money genuinely available for dividends, buybacks and paying down debt — and it is much harder to manipulate than reported profit.

EPS
Earnings Per Share

A company’s profit divided by its shares outstanding. Steadily growing EPS over time is the engine of long-term share-price growth.

DPS
Dividend Per Share

The cash paid to shareholders for each share held. A sustainable, growing dividend is often a sign that reported earnings are backed by real cash.

Goodwill
Goodwill

An intangible asset recorded when a company pays more than book value to acquire another. Large or rising goodwill can flatter the balance sheet and sometimes signals overpaying — worth watching, as it can later be written down.

Reading the financial statements

Balance Sheet
How to Read a Balance Sheet

A snapshot of what a company owns (assets), what it owes (liabilities) and what is left for shareholders (equity) at a point in time. The two sides always balance: assets = liabilities + equity.

Income Statement
How to Read an Income Statement

The profit-and-loss account: revenue at the top, costs subtracted line by line down to net profit at the bottom. It shows whether the business made or lost money over a period.

Cash Flow Statement
How to Read a Cash Flow Statement

Tracks the actual cash moving in and out across operations, investing and financing. Often the most honest of the three statements, because cash is far harder to massage than accounting profit.

Company reporting & news

Full Year
Full Year Annual Results

A company’s most comprehensive report, covering the full financial year — audited, detailed, and usually published two to four months after the year-end. The key event for assessing a business.

Half Year
Half Year Interim Results

A mid-year update covering the first six months. Less detailed and often unaudited, but important for tracking whether a company is on course.

RNS
Regulatory News Service

The official wire for announcements from UK-listed companies, run by the London Stock Exchange — where market-moving news such as results, deals and guidance is released. Oak Growth surfaces only the announcements that actually matter.

Price & momentum signals

RSI
Relative Strength Index

A momentum indicator from 0 to 100. Readings above about 70 suggest a stock may be overbought; below about 30, oversold — a gauge of whether a recent move has run too far.

MA 20/50/200
Moving Averages

The average closing price over the last 20, 50 or 200 days, which smooths out daily noise to reveal the underlying trend. When a shorter average crosses a longer one it signals a shift in momentum — the basis of the golden cross and death cross.

Volume
Volume

The number of shares traded in a period. High volume confirms conviction behind a price move; a move on thin volume is far less reliable.

Commodities & funds

Gold
Gold — the fear gauge

Gold tends to rise when uncertainty, inflation or dollar weakness increase, because investors treat it as a store of value. It often moves opposite to confidence in the wider economy.

Oil
Oil — the economic pulse

Oil prices drive energy-company profits and feed into transport and manufacturing costs across every sector, making them a barometer of global economic activity.

ETF
Exchange Traded Fund

A basket of investments — often an entire index — that trades like a single share, giving instant diversification at low cost.

ETC
Exchange Traded Commodity

Like an ETF, but it tracks the price of a physical commodity such as gold, silver or oil — letting you get exposure without owning the physical asset.

Why Vanguard?
Why Oak Growth Chose Vanguard

Vanguard is among the world’s lowest-cost ETF providers and is owned by its own funds, and therefore its investors, rather than outside shareholders — so its incentives align with keeping costs low for ordinary investors.
