12.1 Equities

Cash equities open Section Nine: Comparative Market Analysis in the 2026 CMT Program Guide. That section sits inside Cross-asset Analysis, part of Advanced Techniques (26% of CMT Level I—the 132-question, 2-hour sitting, 120 scored plus 12 unscored pilots). A technician who already reads bars still has to know what is on the chart: an ownership claim, a price history that corporate actions can break, and a name that may be too thin to trust. Independent OpenExamPrep teaching for these CMT Level I cash-market topics is not a CMT Association publication and does not claim partnership with the Association. Independent CMT Level I practice by OpenExamPrep is at /practice/cmt.

Earlier Theory and History work named four broad asset classes (equities, debt, currencies, commodities) and the instruments that trade them. This unit stays on cash equity securities. Index construction is the next section. Bonds follow. Futures, exchange-traded products, and foreign exchange are the following chapter. Do not import those later definitions here.

Defining equity securities

An equity security is a claim on the residual ownership of a business. Employees, suppliers, tax authorities, and creditors get paid first. What remains of earnings and assets belongs to the owners. That residual can be large, or it can be zero in bankruptcy. That is the economic contrast with a bond: the bondholder's claim is contractual; the stockholder's claim is what is left.

Two listed forms dominate Level I language.

Common stock is the ordinary residual claim. Common holders typically vote for directors, share in residual profits through dividends (which the board may reduce or skip), and keep the upside if the firm grows. In liquidation they stand behind creditors and preferred holders.

Preferred stock is a hybrid. It usually pays a stated dividend and has priority over common for dividends and liquidation, but it typically has limited or no voting power and limited upside. Many preferreds trade more like long-duration credit than like common equity. When a stem says equity without an adjective, it usually means common unless it specifies preferred.

Related claims still show up as stock on a chart. An American Depositary Receipt (ADR) is a U.S.-listed claim on a foreign company's shares. REIT shares are equity from a charting standpoint even though the cash-flow story is property. Tracking stocks and dual-class shares (Class A versus Class C) can print as two prices for one economic firm. Exchange-traded funds (ETFs) are exchange-traded products, not the issuer's own residual claim; they belong in the next chapter. Do not call an ETF the stock of its largest holding.

Benefits of equities for investors

Investors hold equities for economic reasons that also explain why technicians spend so much time on them.

1. Residual upside. A successful firm's earnings can grow without a contractual cap. A 5% coupon bond will not pay 5% of a doubled firm; common equity can.
2. Limited liability. The shareholder can lose the purchase price, not the firm's unpaid debts.
3. Income optionality. Dividends can rise with earnings. They are not a legal promise the way a coupon is.
4. Transferability. Listed common stock can be bought and sold during the session, which is why OHLC and volume exist as a public tape.
5. Voting (common). Governance rights explain some activist headlines; they are not a plotted series.
6. Growth engine in a portfolio. Over long historical samples, diversified equity indexes have outpaced cash and many bond indexes, with deeper drawdowns. That sample is not a promise for the next decade.

For the technician the practical benefit is data. Equities supply long, public, high-frequency price and volume histories on which classical charting was built. That only helps if the history is the economic series per current share, not a raw tape riddled with split cliffs.

Critical market data a technician needs

Unit 2.3 asked which market characteristics technical analysis needs. For a single stock, this unit wants a short list of fields, not a vendor catalog.

OHLC. The open is the first recognized print of the bar; the high and low are the extremes; the close is the last recognized print (for U.S. equities, often the official closing auction). Those four points are the same four the chart-construction chapter used to build bars and candles. Intraday bars have their own OHLC. A line chart that plots only closes throws away the range. Unofficial prints, extended-hours crosses, and halt reopens can differ from the session OHLC your platform labels as daily. If a stem gives a daily candle, use that session's four prices.

Volume. Share volume is a flow of activity, not a second price. Dollar volume (price × shares) compares a $10 name to a $400 name. Relative volume compares today to that name's own typical session. A breakout on a fraction of average volume is a suspect event, not a crowd. Cash equities do not have futures-style open interest; shares outstanding are a corporate statistic, not a tape statistic.

Corporate-action-adjusted series. Raw exchange prints are correct as history of the tape. They are often wrong as history of economic value per current share. After a split, yesterday's $200 close is not support on today's $50 chart unless you restated yesterday. Most professional technical work uses a split-adjusted (and, when the distribution is large, spinoff-adjusted) OHLC series. Dividend adjustment is a separate choice: many price charts leave ordinary cash dividends in as small gaps; total-return charts remove them or reinvest them. Know which series you are on before you call a gap a breakdown.

Float and liquidity. Shares outstanding is the corporate count. Free float excludes shares that are not readily available—insiders, strategic holders, governments, locked-up stock. Index providers such as S&P Dow Jones Indices apply an investable weight factor so cap-weighted indexes use float, not the full share count. A technician uses float because a 20 million-share count with 15 million held by one founder is not a 20 million-share trading vehicle. Liquidity is the market's ability to absorb orders: tight bid–ask spreads, displayed depth, and consistent dollar volume. Classical patterns assume you can transact near the charted price. That assumption fails in many micro-caps and in halted names.

Exam trap: treating market capitalization (price × outstanding) as a liquidity number. A large-cap with a tiny float can be harder to trade than a smaller, fully floated name. Cap tells you size in the index. Float and dollar volume tell you whether the chart is usable.

Effect of corporate actions on price data

A corporate action is an issuer event that changes the number of shares, the economic package attached to one share, or both. The tape will print a new price. The technician's job is to decide whether that print is a market opinion or a mechanical restatement.

Splits and reverse splits

A forward split (for example 2-for-1 or 4-for-1) multiplies the share count and divides the price by the same factor. Market capitalization is unchanged. A holder of 100 shares at $80 becomes a holder of 200 shares at $40. On an unadjusted daily chart the session after the split looks like a 50% crash. Support at $75, a trendline into $80, and a 50-day average near $70 all become nonsense unless history is scaled.

Adjustment rule of thumb: multiply historical OHLC by 1 / split factor. After a 4-for-1, a prior high of $120 becomes $30 on the adjusted chart. Historical volume is often multiplied by the split factor so share counts stay comparable. Reverse splits do the opposite: a 1-for-10 reverse split turns $2 into $20 and can create the optical illusion of a moonshot on an unadjusted chart.

Worked numbers. Close $180. 3-for-1 split. Post-split reference price $60. Unadjusted percent change: −67%. Economic change from the split itself: 0. Any trendline, measured move, or percentage trailing stop that used the $180 close without adjustment is invalid.

Dividends

On the ex-dividend date the buyer is no longer entitled to the declared dividend, and the share price typically drops by about the dividend amount (taxes and microstructure can make the gap a little different). A regular quarterly dividend of $0.40 on an $80 stock is a 0.5% gap—easy to ignore on a weekly chart, enough to fake an intraday breakdown. A special dividend of $10 on a $50 stock is a 20% gap. That is not a 20% verdict on the operating business; it is cash leaving the firm.

Vendors differ. Some adjust historical closes for all dividends (a total-return-style price). Some adjust only for special dividends above a threshold. Some adjust only for splits. If two platforms disagree on a 2018 low, check the adjustment policy before you argue about the pattern.

Spinoffs

A spinoff distributes shares of a subsidiary to the parent's holders. After the distribution, the parent is a smaller economic package, so its price drops by roughly the value of the spun company. An unadjusted parent chart looks like a crash or a gap down. Combined wealth (parent plus spinoff) may be little changed.

To keep the parent chart usable, data vendors typically back-adjust the parent's history by the spinoff factor, or they offer a spliced series. If you study the spun company, its pre-spin history may be a when-issued stub or may not exist as a listed tape. Do not treat the parent's unadjusted gap as a classical breakdown without checking the distribution.

Other actions that rewrite a series include stock dividends (economically close to a split), rights offerings, mergers that retire a ticker, and reverse splits used to meet listing-price rules. Mergers and delistings also feed survivorship bias in the next section: the name disappears from today's list even though it was on yesterday's chart.

Why adjusted charts matter. Trendlines, moving averages, percentage retracements, measured pattern objectives, and any backtest that uses percent returns will lie if a split or spinoff is left as a raw cliff. The 2026 Program Guide asks you to explain the effect of corporate actions on price data because a technician who cannot tell a 4-for-1 restatement from a 75% panic will misread every subsequent indicator.

Classifying equities: sectors, capitalization, and other segments

Comparative market analysis is classification plus relative strength. You do not need every taxonomy. You need the ones Level I uses to segment the market.

Sectors

The Global Industry Classification Standard (GICS), maintained by S&P Dow Jones Indices and MSCI, is the sector map most U.S. equity work uses. GICS currently has 11 sectors: Energy; Materials; Industrials; Consumer Discretionary; Consumer Staples; Health Care; Financials; Information Technology; Communication Services; Utilities; and Real Estate.

Real Estate became a standalone GICS sector in 2016 (it had lived under Financials). Older materials that say 10 sectors are stale. GICS then splits into industry groups, industries, and sub-industries; Level I items usually stop at sector or a named industry group (banks versus insurers, hardware versus software).

Sector work matters because leadership rotates. A strong index high led only by Information Technology is a different tape from a high led by Energy and Financials. Breadth and relative-strength chapters will operationalize that. Here, remember that a stock is also a sector citizen. Other maps exist (ICB, vendor custom groups). If a stem names GICS, use the 11.

Capitalization

Market capitalization = last price × shares outstanding. Float-adjusted cap uses float instead of outstanding. Size buckets are conventions, not a natural law, and dollar cutoffs drift as the market rises. Do not memorize one blog's $10 billion large-cap line as a CMT Association number. Do memorize the index families that practitioners use as size proxies:

FTSE Russell reconstitutes its U.S. size indexes on a published calendar (semi-annual beginning in 2026). Membership changes can gap a small-cap product when names migrate. That is an index event, previewed here because it hits the stock you are charting.

Other segments

Beyond sector and size, Level I language includes:

• Style: growth versus value (Russell and S&P style indexes).
• Geography: domestic versus international; developed versus emerging; ADRs as a U.S. tape on a foreign issuer.
• Listing venue: NYSE, Nasdaq, and other listed markets versus thin OTC names.
• Cyclical versus defensive: discretionary, industrials, and energy versus staples and utilities—a business-cycle cut that overlaps GICS.
• Share class: dual-class votes can chart as two prices for one firm.
• Payers versus non-payers: dividend streams versus total-return behavior.

The point of the list is not to recite every label. It is to answer a stem that asks how else the equity universe is segmented once sector and cap are named: style, geography, listing quality, and cycle sensitivity.

Exam habits for this unit

When a question shows a stock gapping 50% overnight, ask whether a split, special dividend, or spinoff hit. When a question asks what data a technician needs, list OHLC, volume, an adjusted history, and float/liquidity—not the firm's PE ratio. When a question asks how to classify names for comparative work, start with GICS sectors and capitalization, then add style or geography if the stem requires a third cut.

Key Takeaways

• Equity is residual ownership; common stands behind creditors; preferred is a hybrid
• Listed equities give investors upside, limited liability, and a public OHLC/volume tape
• Critical fields: OHLC, volume, corporate-action-adjusted history, float, liquidity
• Splits, dividends, and spinoffs restate per-share value; unadjusted cliffs fake panics
• Segment by GICS's 11 sectors, cap proxies, then style / geography / listing / cycle
