  • Earnings per share

    Net income attributable to each outstanding common share; diluted EPS also reflects common-share equivalents from potentially convertible or exercisable securities.

  • Easy to Borrow (ETB)

  • ECN (electronic communication network)

    An electronic trading system that displays orders entered into it and lets other participants trade against them. Traders also use "ECN fees" loosely for the per-share fees and rebates venues charge or pay on each fill.

  • F-1

    Registration statement for foreign private issuers. The form alone does not identify a PIPE, equity line, completed sale, or effectiveness status.

  • F-3

    Short-form registration for eligible foreign private issuers. Verify the offering structure, registration evidence and applicable limits separately; the form is not a measure of available shelf capacity.

  • F-10

    Registration form for certain Canadian issuers under the multijurisdictional disclosure system. It is a separate form family, not an S-3 or F-3 filing.

  • Failure to Deliver (FTD)

    An FTD occurs when securities are not delivered when settlement is due. Fails can arise from short sales, long sales or processing issues; they differ from outstanding short positions (short interest).

  • Gap fill

    A return of price to the prior session's close after an opening gap. A gap-fill count states whether it means a full or a partial fill (such as the gap midpoint) and whether an intraday touch or the session close is the basis.

  • General Partner

    The person or entity that raises capital for, controls, invests, and manages a private fund organized as a limited partnership.

  • General Solicitation

    Broad marketing activity that conditions the market for a securities offering; some exemptions allow it under conditions while others prohibit it.

    In U.S. intraday equity trading, LD commonly refers to the lower side of the Limit Up/Limit Down price-band mechanism. It addresses executions below the lower band, separately from SSR.

  • Limit Up (LU)

    In U.S. intraday equity trading, LU commonly refers to the upper side of the Limit Up/Limit Down price-band mechanism. A band indication is not itself a confirmed trading halt.

  • Limit Up / Limit Down (LULD)

    LULD is the U.S. NMS equity plan preventing executions outside upper and lower price bands during regular hours. Under specified conditions, a limit state can lead to a trading pause.

    A contractual right giving an investor priority payment in a sale, winding-up, or similar event, often expressed as a multiple of invested capital plus specified dividends.

    The short code on Level 2 that labels which exchange, market maker or other participant is displaying a quote. FINRA's rules call it a market participant symbol (MPID).

    A period with measurably different trading conditions (for small caps: gapper counts, volume, the share of gappers holding gains), labelled with a rule known before each session.

  • Marketable limit order

    A buy limit order priced at or above the national best offer, or a sell limit order priced at or below the national best bid, when the order is received. It can trade at once, but only up to its limit price.

  • Maturity Date

    The contractual date by which a borrower must make the final payment on a loan or other debt instrument.

  • Non-Accelerated Filer

    A reporting company that does not meet accelerated- or large-accelerated-filer criteria, often because of float, revenue eligibility, or limited reporting history.

  • Off-exchange (TRF) print

    A trade executed away from the exchanges, for example by a wholesaler, an alternative trading system (dark pool) or another broker-dealer, and reported afterwards to a FINRA facility. On the consolidated feed for Nasdaq-listed stocks it carries market center code D.

  • Opening cross (opening auction)

    The auction that sets a stock's official opening price by matching eligible orders at a single price at the start of regular trading. Nasdaq calls its version the Opening Cross.

    Overhead costs of running the business, often called selling, general, and administrative expenses, excluding direct production or service-delivery costs.

  • Outcome bias

    Judging the quality of a decision by how it turned out rather than by what was knowable and controllable when it was made.

    Tuning a rule's parameters until it fits the noise of one sample, so its in-sample result overstates what it does on new data.

    Trader shorthand for a price run that steepens, with bars climbing faster and ranging wider than before. It is measurable only through stated rate and range-expansion rules.

  • Performance Fees

    Adviser compensation linked to investment performance, commonly a percentage of profits above defined terms; carried interest is a common private-fund form.

  • Public Offering

    An offering made to public investors. It may include securities sold by the issuer, existing holders, or both; public versus private and primary versus resale are separate classifications.

    An investment that counts toward a venture-capital fund's qualifying-investment requirement, generally direct equity in eligible private operating companies rather than debt, secondary, or fund interests.

  • Qualifying Venture Capital Fund

    A venture capital fund that can use the expanded 3(c)(1) owner limit when it stays within the SEC page's owner, capital, and venture-fund conditions.

  • Queue position

    Where a resting limit order stands among the orders waiting at the same price on one venue. Orders ahead of it trade first, so a touch of the price is not the same as a fill.

  • R-multiple

    A trade's result divided by its planned risk. 1R is the amount a trader planned to lose if the stop was hit; a result of +2R made twice that amount.

  • Risk/reward ratio (R:R)

    A trade's planned target distance divided by its planned stop distance, such as 2:1 for a 10-cent target and a 5-cent stop. The realized version is average net win divided by average net loss.

    A transaction fee set by the SEC under Section 31 of the Securities Exchange Act, charged on the dollar value of covered sales. Brokers usually pass it through on each sell.

  • Secondary Market

    A market where investors trade securities that already exist, rather than buying newly issued securities from the company.
