What's New

October 15, 2026

• The Decision Card shows Peers: up to six other names in the same industry with a call on the Decision Record, with their verdict, durability, demandingness, return on equity and price to book. It also shows when the verdict last changed, and a Trend falling marker beside the verdict when the return it reads has been falling. Neither changes the call.
• Analyzing a symbol no longer adds it to the active portfolio. The symbol appears below the holdings with an Add shares button, and a row exists only once you enter shares. A removed row stays removed when your devices sync, and each browser opens on the portfolio you last picked in it.
• Email link sign-in asks only for your email when you already have an account, and the sign-in page says Restoring your session while it restores a stored sign-in instead of showing the form.

October 13, 2026

• The Monitor can show an adjusted cost for a stock that has earned option premium. Sell a 325 put for 2.00 against 100 shares bought at 350.00, let it expire worthless, and the stock reads an Adjusted cost (includes option premium) of 348.00, with the original 350.00 and the 200.00 collected listed beneath it. Premium counts only once the option has expired or been bought back; one still open shows as Premium pending. An assigned put puts its premium on the shares it delivered (strike less premium), and an assigned call shows its premium as added to the sale proceeds.
• A Basis switch on the Monitor stock table moves between Adjusted and Original cost. The adjusted figure is an economic view and is never used for tax lots, holding terms, wash sale marks or realized gains, which stay on the original records. Log premium, in the expanded stock row and on any option row, records an option; a Confirm option outcomes list asks what happened to options whose expiry has passed rather than assuming.

October 9, 2026

• Every yield on the site now comes from one checked calculation, the TTM distribution yield: the cash distributions per share with an ex-dividend date in the last twelve months, divided by the price. It replaces a figure the data provider pre-computed, which for a Treasury bond fund read about 2.8% where the fund's own distributions add up to about 5.0%. The Fundamentals dividend card, the Compare table, the Monitor and the Annual Div figure in Portfolio Analytics all read it, and the Monitor column sorts by the figure it shows.
• A yield appears only when the distribution history has been checked. If a payment looks missing, or the history cannot be verified, the row reads Unavailable with the reason on hover, instead of a number that only looks right. A 0.00% means the full twelve months were covered and a second signal agreed that nothing was paid. Hover any yield for its formula, window, price, source and age.
• The forward yield (the latest regular payment, annualised) and the 30-day SEC yield are separate rows, and one is never shown in place of another. The 30-day SEC yield is the fund issuer's own figure and is not available from our data sources, so it reads Unavailable; it is never calculated from payment history.
• An ex-dividend date is shown on the day the provider names. It could read one day early in the United States.

October 8, 2026

• Your Notes keep earlier versions. When a save deletes the note, cuts it to under half its length, or changes it after ten quiet minutes, the text it replaced is kept (the sixty most recent), and an Earlier versions link under the box lists them with their time, size and first words. Restore puts one back, and the text it replaces is kept too, so a restore can be undone. Your browser also keeps the text another copy replaced, for example when a note from another device arrives, and lists it as kept on this device. The box is read only, saying Loading your notes, until your saved note has arrived, so nothing typed in that moment can replace it.
• Adding shares for the first time includes a purchase date. It starts at today, and you can change it before you save. Saving stores that date, so the position list shows the day bought. A position imported without a purchase date stays not on record until you enter one.
• The Value Graph's normal multiple line now runs through the live date, the same span as the price and the fair value. It applies this stock's own normal multiple to forward earnings per share. The multiple is still the average of the reported years only.
• On the Value Graph, the last segment of fair value is dashed and the last segment of the normal multiple is dotted, and both live points are diamonds. That segment multiplies forward earnings per share, so a jump there is a change of earnings. The price line stays solid.
• The intrinsic value box names its earnings as trailing, and shows when growth was held between minus 4% and 25% and what the rate on record was. When an earnings growth rate is not on record, it says the rate is revenue growth.
• Research Deep Dive has a Suppliers tab. It lists up to ten companies that supply the company on screen, each with its stock symbol (the word Private when it is not publicly traded) and what it supplies. A row marked Annual report is named in the company's own annual report, and its sentence opens when you tap the label. Rows marked General knowledge are widely reported relationships added to fill the list, and carry no amount. Companies rarely publish what they spend with one supplier, so an annual purchase amount, and the next three years projected from it, appear only where a filing gives one: the company's own annual report, or a supplier's annual report stating what share of its sales this company is (marked from the supplier's report, with the sentence and the sum one tap away); every other cell reads Not disclosed. The company's total purchase commitments, from all suppliers together, sit above the table.
• The Value Graph chart shows in full on a phone, and the price chart keeps its height after a visit to the Value Graph. Right after a site update, when a source has not answered yet, the figures read Loading and try again by themselves, or use an earlier reading with its date, instead of reading Unavailable.
• An administrator can mark a specific account so email and password finish the sign-in, with no authenticator code, on the website and in the mobile app. Every other account is unchanged.

October 7, 2026

• The Portfolio Analytics header shows P/L beside Net Liq: the open profit and loss on the positions held, current value minus cost, in dollars and percent. The day's move stays, labeled Day.
• The Decision Card heading stays with the symbol being read. Switching symbols clears the previous company's name and figures, and a failed filing fetch asks for a retry instead of showing insufficient evidence.
• Research Deep Dive's competitor table fills market value, revenue growth, margins and free cash flow yield from the same figures as the Fundamentals cards when that first read came back empty. A report already on file is updated in place.
• Research Deep Dive has a Notable Holders tab. It lists up to ten hedge funds and well known investors with a substantial position, and each row shows whether the latest filing increased or decreased the shares, by how many, and the report date. Index funds, banks and pensions are left off.
• Flagged orders and the out-of-the-money put board are kept in memory. A site update clears them until the next Scan now, or until the weekday 10:45 Eastern put scan. Opening the put section also builds it once if it is empty.
• Portfolio X-Ray price history is kept in memory and fetched again after a site update. The first open of a large book after an update takes longer while those prices are read.
• After a site update, and until the next weekday morning scan, the EFM board shows the names from the signal journal (those at or above the threshold) rather than the full scored list. Signal history is unchanged.
• Opening a news headline now names the article and includes the stocks and facts the article states. The reading links the article. A headline about specific stocks is answered from those names, and a page that cannot be read says which article could not be read.

October 6, 2026

• Value Graph now prices the live quote against forward earnings per share for the next twelve months, and keeps each earlier year on that year's reported earnings per share and the monthly close nearest that period. The summary says how far the share price sits from that fair value (overvalued, undervalued, or fairly valued). A year with no reading is left blank, and the normal multiple is left off when there are not enough reported years to support it.

October 5, 2026

• Decision Card rules version 4 (v4, bank-v4 and insurer-v4). For banks and insurers, the return on equity a call is built on is now weighted toward the latest of the last three filed years (half the latest, three tenths the year before, a fifth the oldest) instead of a plain average, and the card prints the latest year, the average, the weighted figure and the direction in its reasons. Operating companies are still scored on their latest year's return on invested capital, with the three-year average and the direction printed beside it as a reading. An input that looks wrong beside the income statement (a grade of B or better with a return under 4 percent) is now checked against the company's own filed statements before a call is issued: confirmed, corrected, or the card reads Input under review and gives no call. A card no longer issues a call on stale filings, and says so: awaiting the next quarter's filing when it has not been filed, or that the filing is out but not yet in our data when it has. Bank of America and Cincinnati Financial are now priced on their June 30 balance sheets instead of March 31 (preferred stock carried forward while its share count is unchanged, and the report's cover share count). Every card now states the period its filings run through, prints "Grades rate the business. The verdict prices it.", and shows a boxed Call weakening notice, with the count and which conditions, when two or more of its own disconfirm conditions are already broken. That notice never changes the verdict. Calls already published stay as published.
• The Decision Card's bank and insurer standards (now bank-v3 and insurer-v3) read common equity, after preferred stock, instead of total equity, and price the stock against the newest book value on file, the latest quarter rather than the last fiscal year, with its date printed on the card. A price that cannot be matched to the filed share count, as for Berkshire Hathaway's two share classes, now shows no call instead of a number.
• Bank calls now show the efficiency ratio as filed beside the call: noninterest expense over net interest income plus noninterest income, for the last six fiscal years and the latest quarter. It is a reading taken from the company's filings, frozen with the call on the Decision Record, and never part of the score.
• Bank calls also show the common equity tier 1 ratio the bank reports in its annual report (and its newest quarterly report where it tags the figure), for the holding company and dated, read from the report's own capital table. It is shown only for banks whose tables have been checked, and it is never part of the score.
• Bank calls now also show the net interest margin the bank reports (JPMorgan Chase, Bank of America, Capital One, SoFi and Schwab), and property and casualty insurer calls show the combined ratio the insurer reports (Travelers and Chubb). Each is the company's own figure on the company's own basis, read from the text of its latest annual and quarterly reports, shown only when the company states it twice and the two agree, dated, and never part of the score. Where a company's report has not been checked, the card says so instead of showing a number.

October 2, 2026

• Social Arbitrage now pins the symbol open in the workspace at the top of the board as Analysis stock, with the same readings as the ranked rows. Opening it adds a table of StockTwits, Reddit, news tone, the blend of the venues that could be measured, and how busy the conversation is, plus a written bull and bear note built only from those messages.
• The Decision Card now issues a call for banks, lenders and insurance underwriters. Banks and lenders are read from return on equity, book value per share, the share count and assets per dollar of equity (now bank-v3). Underwriters use the same book reading, with book value per share weighted ahead of return on equity, and filed revenue per dollar of equity in place of leverage (now insurer-v3). A price under 0.8 times book while return on equity is already below 10% is treated as a writedown, not a bargain. Property trusts and insurance brokers still show no call. These standards sit beside the operating-company standard (v3) and do not rewrite an existing v3 call.

October 1, 2026

• Portfolio X-Ray now reads the whole year for the book however recently some holdings were listed (a young name no longer shrinks the window and moves the beta), always says what its selloff reading found, shows the book on four regime axes with a Partial read label when fewer report, keeps funds in their own bar in the sector gap, and names the leveraged and inverse funds in the scenario replay. IREN is read as Technology.
• Added Portfolio X-Ray to Portfolio Analytics: how many independent bets your holdings really are, which positions carry most of the risk, how the book leans against the market, growth and value, size, momentum, quality and interest rates, how your sector weights compare with the S&P 500, how strongly your holdings move together in a selloff, and whether that lean fits the current backdrop. A scenario replay shows which holdings would have hurt most in the COVID crash, the 2022 rate shock, 2018's fourth quarter or the 2008 crisis, or in a window you choose. It describes the book and never suggests a trade.
• The portfolio donut and Portfolio X-Ray now show real sectors even when the quote source returns none: each company's sector is read from its own filing record at the Securities and Exchange Commission. It is an approximation, so the panels say how many sectors came from it, and funds keep their own labels instead of being given a guess.
• Positions held under a ticker the data providers no longer use (for example FI for Fiserv, now FISV, and MMC for Marsh McLennan, now MRSH) now price correctly, count toward your portfolio total and appear in Portfolio X-Ray, instead of showing as unpriced.
• Rebuilt Benchmark Comparison on SPY, QQQ and IWM price history over one day, week, month, three months, year to date and one year, with a one-year chart. The old comparison used futures and one day only, and called a one-day gap alpha; it is now the difference in percentage points.
• Sector Flow now keeps relative strength and fund flows apart. The quadrants are labelled as relative strength against SPY, actual ETF net flows for 1, 5 and 21 days sit beside them, and the written summary can only call a sector an inflow when the flow numbers say so. When strength and flows disagree, it says that.

September 30, 2026

• Added WACC (estimated) and the value creation spread to the Fundamentals panel, beside ROIC: an estimated cost of capital built from the company's own filings, today's share price and the 10-year Treasury yield, and ROIC minus that cost, green when the business creates value and red when it does not. The equity risk premium is adjustable on the card, and every assumption is listed with its date.
• The homepage market briefing now reads CNBC and MarketWatch headlines as well as its existing feed, names upcoming economic releases (consumer prices, jobs, personal income and outlays, gross domestic product and more) beside Federal Reserve meetings and Treasury auctions, and adds a card with the new figure against the month before on the day an inflation report comes out. It refreshes shortly after each 8:30 release.
• Headline cards on the market briefing now show the publisher and time, a More button with the publisher's summary of the story, and Read article, which opens the story in a popup window. Personal finance advice columns no longer appear on the board.

September 26, 2026

• Added the Decision Card: one dated call on a stock (high-conviction buy, buy and watch, hold with no edge, sell, or insufficient evidence), with the reasons, the facts that must remain true, and a twelve-month horizon. Banks, insurers and incomplete filings abstain rather than guess.
• Added the Decision Record: a public, dated list of those calls on S&P 500 companies, graded twelve months later against the S&P 500. A hit rate is shown only after thirty directional calls have been graded. No sign in required at quantamatica.com/decision-record.

September 24, 2026

• Added a track record to your theses: each one records the stock and the S&P 500 on the day it is written and the day it is closed, and Conviction shows how the stock did against the market while you held the view, thesis by thesis and in total.
• Added Conviction: business quality, capital compounding and what today's price implies, side by side for one stock, plus a dated thesis you write with conditions that would prove it wrong. The conditions are checked every weekday evening, and you can choose to be emailed the first time one breaks.

September 22, 2026

• Added Capital Compounding to Research Deep Dive: return on invested capital by fiscal year against a stated cost of capital, the return on new capital and how much profit is reinvested, owner cash flow per share after stock pay, dilution and buybacks, all from the company's filed statements.
• Added a reverse discounted cash flow to the DCF model: it solves for the growth rate today's price already assumes, sets it against the company's own revenue growth and cash flow margin, and can count stock-based compensation as a cost. The model's starting cash flow now comes from the company's filed free cash flow, and it opens at the growth rate today's price implies, so it starts at roughly the current price.

September 15, 2026

• Added a live global indices tape across the top of the homepage, with prices and day change, refreshing every two minutes and on demand.

September 14, 2026

• Redesigned the homepage below the hero, with real, sourced statistics about the platform in place of generic marketing copy.
• Added a capital gains summary to the Portfolio Monitor: short-term, long-term, and combined gains for the current calendar year.

September 13, 2026

• Added a Short Interest reading to Fundamentals, with history plotted against price.
• Added Valuation Drivers: share price and book value per share indexed together on one chart, so the two can never imply different stories about a stock.
• Share lots now record full purchase and sale history, including short sales, wash sale detection, and a closed positions section for stocks you have fully sold.

September 11, 2026

• Launched the public inflation calculator, no sign in required, using the Consumer Price Index back to 1913.
• Added a Consumer Credit page, tracking delinquency and charge off rates by loan type against their own history.
• Added Quantum Computing as its own theme inside Technology on Sector Flow.

September 10, 2026

• Added the Producer Price Index to the inflation strip.
• Added day move markers to the price chart, with an adjustable percent or point threshold.
• Added Grade, EFM, and Q reference readings to the chart toolbar.

September 9, 2026

• Added a deterministic Income Statement tab to Research Deep Dive, with a rules based fundamentals grade.
• Added a one day horizon to the Probabilistic Forecast.

August 29, 2026

• Replaced login-only activity tracking with Last Active, based on time actually spent signed in rather than only the last authentication.

August 27, 2026

• Changed the portfolio panel to keep only one unpriced search result at a time, so a portfolio's holdings list stays clean after searching for new tickers.
