Asset class

Cash Equities

Direct ownership instruments — shares and the funds that wrap them. The simplest claim on a company's future.

The market at a glance

Cash equities are the ownership layer of capitalism: roughly $100+ trillion of global market capitalisation spread across some 50,000 listed companies, traded on exchanges from New York (NYSE, Nasdaq — together about half of world market cap) to Tokyo, Shanghai, London and Frankfurt. "Cash" distinguishes buying the actual share — settled and owned — from derivatives that merely reference it.

The participants form a food chain: retail investors and their advisors at the base, index funds and ETFs (now ~half of US fund assets) as the passive middle, active managers, pension funds and sovereign wealth funds allocating at scale, and market makers and high-frequency traders supplying the liquidity everyone else consumes. Companies themselves are major buyers via buybacks — in many years the single largest source of net demand for US equities.

What actually drives share prices

  • Earnings and expectations. In the long run, share prices follow earnings per share; over months, they follow revisions to expectations more than levels.
  • Discount rates. Equities are long-duration assets: when bond yields rise, future profits are worth less today — the mechanical link between rates and stock valuations.
  • The equity risk premium. Stocks have returned roughly 4–6% per year above government bonds over the last century — payment for enduring drawdowns that regularly exceed 30–50%.
  • Flows and positioning. Index rebalances, buyback windows, options-hedging feedback and fund flows move prices with no news at all.

How the products fit together

Start with common stock — the atom. Preferred stock trades equity upside for bond-like income and priority. ETFs and mutual funds wrap diversified baskets into single tickets — the difference is intraday tradability and the creation/redemption machinery. ADRs/GDRs import foreign shares to your home exchange, and REITs push property cash flows through the equity wrapper.

Key concepts to master

Valuation always reduces to discounting. Whether dressed as P/E multiples, DCF models, or dividend yields, every valuation asks: what are future cash flows worth today? The dividend discount model is the cleanest teaching version — try it below and watch how brutally sensitive fair value is to small changes in the growth/discount gap. That sensitivity is equity volatility, explained in one formula.

$$ P_0 = \frac{D_1}{r - g} \qquad \text{— the Gordon growth model} $$
What the symbols mean
  • Pa price, or a present value
  • Dduration: how far a bond's cash flows sit in the future
  • rthe interest rate, per year
  • ga growth rate, per year

Educational model with heroic assumptions (constant growth forever). Real analysts use multi-stage versions — but the sensitivity you see here is real.

Risks the brochure understates

Single stocks can and do go to zero — diversification is the only free lunch here. Drawdowns arrive clustered, not smoothly. And valuation discipline matters most exactly when it feels most irrelevant: buying "great companies at any price" has repeatedly cost investors a decade of returns. The product pages below give each instrument's specific risk profile.

Gains as share of final value

Assumes a constant return with monthly compounding — real markets deliver the average by way of violent detours, and costs and taxes take their cut.

Interactive: drawdown & recovery mathStarter

Losses and gains are not symmetric, and the asymmetry gets worse fast. This is the arithmetic behind every risk-management rule.

If the drawdown doubles

Recovery gain = d/(1−d): −30% needs +42.9%, −50% needs +100%, −80% needs +400%. Avoiding the deep hole is worth more than catching the sharp rally.

Interactive: lump sum vs. spreading it inStarter

The question every inheritance, bonus and house sale raises: invest it all now, or feed it in monthly?

Reading

Assumes a constant return, so lump sum mathematically wins whenever expected returns are positive — the historical evidence agrees about two thirds of the time. What spreading in actually buys is a smaller worst case and a much smaller chance of regret, which is a real benefit the arithmetic can't price.

Deep diveWhy equities compound — and what it costs to collect

Broad equity indices have out-compounded every mainstream asset class over long horizons — but the excess return exists because holding through the drops is hard.

Stylised long-run growth of 100: equities out-compound bonds and cash — via a much rougher ride.
EquitiesBondsCashTime (decades)Growth of 100 (log scale)
  • The premium is payment for pain — no drawdowns endured, no excess return earned.
  • Time in beats timing — missing the handful of best days (which cluster next to the worst) destroys decades of edge.
  • Fees compound like returns — 1.5% extra annual cost eats roughly a third of final wealth over 30 years (calculator above).
  • The real risk isn't volatility — it's being forced, financially or emotionally, to sell at the bottom.
Deep diveBear markets: the price of admission

Roughly once a decade equities fall 30–50%, and every time it feels like new, permanent information. It never has been — yet.

A stylised index path around its long-run trend: the trend is only visible afterwards; the bears are what you feel at the time.
BearBearIndex pathLong-run trendTimeIndex level
  • The track record: 1974, 1987, 2000, 2008, 2020 — different causes, same shape, trend eventually reclaimed.
  • "Eventually" varies wildly — months (2020) to a decade-plus in real terms (2000).
  • Rule 1: money needed within a few years doesn't belong in equities — forced sales convert temporary loss into permanent loss.
  • Rule 2: judge any strategy by worst peak-to-trough and recovery time, not average return.
Deep diveHow an order becomes a trade

Between "buy" and owning shares runs a machine: broker → venue → order book → clearing → settlement. Knowing it saves real money.

  • Order book: resting limit orders stacked by price; the bid–ask gap is the toll — pennies on large-caps, real money on small-caps.
  • Market order = execute now at whatever the book offers. Limit order = your price or nothing.
  • Settlement follows at T+1 (US) / T+2 (most of Europe) via clearing houses you never see.
  • US retail flow mostly goes to wholesalers ("payment for order flow") — banned in the EU, debated in the US.
  • Practical: use limit orders for anything illiquid, at the open, or in turbulence; liquidity is worst at the open, strange in the closing auction (~a quarter of daily volume).
Deep diveMilestones: how equity markets got here

Today's market structure is scar tissue from four centuries of episodes:

  • 1602 — the Dutch East India Company issues freely transferable shares in Amsterdam: the first stock market.
  • 1792 — 24 brokers sign the Buttonwood Agreement: the NYSE's founding document.
  • 1929–34 — the Crash, then the Securities Acts: disclosure, the SEC and the modern regulatory template.
  • 1971 — NASDAQ opens as the first electronic quotation market.
  • 1976 — Bogle launches the first retail index fund; "just buy the average" becomes investable.
  • 1987 — Black Monday: −23% in one day; circuit breakers follow.
  • 2010 — the Flash Crash: algorithms meet thin books; audit trails and kill switches follow.
  • 2020s — zero-commission retail, options mania, T+1 settlement (2024): the market's newest experiment runs live.

Three numbers, one sanity check: what return does this P/E imply, and does it beat just owning a bond?

Reading

Crude by design: earnings yield plus growth is a back-of-envelope expected return, not a valuation model. It exists to catch the cases where the envelope already says no.

Deep diveWho runs this market

Knowing the institutions is half of reading the news about them:

  • Venues: NYSE, Nasdaq and Cboe in the US; Euronext, Deutsche Börse (Xetra), the LSE, SIX in Europe; JPX, HKEX and the Chinese exchanges in Asia. Most now run several order books plus auctions.
  • Liquidity providers: electronic market makers — Citadel Securities, Virtu, Jane Street, Optiver — quote the bulk of continuous volume; the old floor specialists are a museum exhibit.
  • Index providers: S&P Dow Jones, MSCI, FTSE Russell and STOXX decide what "the market" is. Their rulebooks move billions on rebalance days — index membership is itself a price-moving event.
  • Post-trade: DTCC clears and settles almost all US equity trades; Euroclear and Clearstream do the European heavy lifting. Custodians (BNY, State Street, JPM, Citi) hold the assets.
  • Regulators: the SEC and FINRA in the US; ESMA plus national authorities (BaFin, AMF, CONSOB) under MiFID II in the EU; the FCA in the UK.
  • Where the data lives: exchange feeds and the consolidated tape; company filings (EDGAR in the US, national registers in Europe); index factsheets — all free and more reliable than any aggregator.
Deep diveNumbers & conventions worth memorising
ItemConvention
SettlementT+1 in the US and Canada since May 2024; T+2 across most of Europe and Asia
QuotingPrice per share; US options-linked names in cents, European names in local currency
Typical spreadAround 1–3 basis points on mega-caps; tens of basis points on small caps and wider still in stress
Closing auctionRoughly a fifth to a quarter of daily volume in developed markets
Index rebalanceUsually quarterly, announced in advance — the flow is predictable and heavily traded
DividendsQuarterly in the US, mostly annual or semi-annual in Europe; the price drops by roughly the dividend on the ex-date
Free floatIndex weights use tradable shares only — founder and state stakes are excluded

The one rule of thumb worth more than the rest: a stock's liquidity, not its story, sets your realistic position size. If your intended trade is a meaningful share of a day's volume, you are the market, not a participant in it.

Analysis

AnalysisThe analyst's checklist

Six questions, in this order. Skipping straight to valuation is the most common way to be precisely wrong.

  1. What does it sell, to whom, and why do they keep buying? If you cannot state the revenue model in one sentence, nothing downstream is reliable.
  2. Does it earn more than its cost of capital? Return on invested capital above the weighted cost of capital is what separates a compounding business from a treadmill.
  3. How is it financed? Debt maturities, interest cover, and share count over five years — dilution is a cost that never appears on the income statement.
  4. What is already priced in? A P/E is a forecast in disguise: work out what growth and margins the price implies, then ask whether that is a bet you want.
  5. Who else owns it and why? Index membership, crowded positioning and a thin free float make the price about flows, not fundamentals.
  6. What would make me wrong? Write it down before buying. If you cannot name the disproof, you have a belief, not an analysis.
AnalysisRed flags
  • A dividend yield that is high because the price collapsed — the market is forecasting the cut, and it is usually right.
  • Earnings rising while operating cash flow does not — the gap is where accounting choices live.
  • Perpetual "adjusted" earnings: if restructuring charges recur every year, they are not one-offs, they are costs.
  • Buybacks that only offset dilution — the share count tells you which it was.
  • A valuation that needs a decade of perfection to make sense; great companies and great investments are different questions.
  • Your position versus daily volume: if exiting takes days, you own an illiquid asset regardless of the listing.
Market mapWho is on the other side of your trade

Prices are made by participants with different jobs, different constraints and different reasons to trade. Knowing whose need you are meeting explains more about a market than any indicator.

  • Index funds are now the largest holders in most developed markets. They do not have a view — they buy what the index says, on the day it says. That makes index inclusion and exclusion a real, dated flow event.
  • Market makers quote both sides and want to end the day flat. They are not your opponent; they are renting you immediacy, and the spread is the rent.
  • Active managers are measured against a benchmark, which makes them structurally reluctant to deviate far from it. Much of what looks like conviction is tracking-error budgeting.
  • Corporates themselves, through buybacks, have been among the largest net buyers of their own market for a decade. That flow is pro-cyclical: it is largest when cash is plentiful and prices are high.
  • Retail is a small share of volume and a large share of the narrative. In individual small-caps that reverses, which is why those are the names where crowding matters most.
Costly mistakesThe five mistakes that cost the most here

Not a list of ways to be clever — a list of the errors that recur, why each one is structural rather than careless, and which tool on this site settles it.

  • Judging a company by its share price history. The price says what other people paid, not what the business is worth. Every valuation question starts after the chart is closed.
  • Confusing dividend yield with return. A yield that rises because the price fell is a warning. Read it alongside the payout ratio and the cash flow that funds it.
  • Ignoring the currency. A foreign holding is two positions. Over a decade the currency can be the larger one, and it was never the decision you thought you were making.
  • Buying an unfamiliar index because the name sounds broad. Country, sector and single-stock concentration inside an index vary enormously — read the top ten holdings before the fact sheet's headline.
  • Trading with market orders in thin names. A market order takes liquidity at any price. In a thin book that is a real and avoidable cost.
