The words buried in filings that retail traders never read, until the price already moved.
The alpha isn't hidden. It's unread.
Every dilution, every insider exit, every going-concern warning is sitting in a public filing on EDGAR, usually before the chart tells you anything. The price is downstream of the filing. The traders who get smoked by a “surprise” offering weren't unlucky; they just didn't read the document that announced it.
Here are 10 phrases that consistently move stocks. Learn to spot them and you stop being the exit liquidity.

01
"Substantial doubt about its ability to continue as a going concern"
What it meansThe company's own auditors are formally warning they may not have enough cash to survive the next 12 months.
Why it moves the stockA flashing red light for solvency, and it almost always precedes a capital raise (dilution) or a much lower price. The market often reprices hard once this language appears or is reiterated.

02
"Shelf registration" / Form S-3
What it meansThe company pre-registers the ability to sell stock (or debt) later, on short notice: a loaded gun, not a fired one.
Why it moves the stockThe infrastructure for future dilution. Rarely tanks day one, but it's the permission slip, and small/micro-caps frequently tap it within weeks or months.
Where it shows up
S-310-Q424B5
03
"At-the-market (ATM) offering"
What it meansA program letting the company drip new shares directly into the open market at prevailing prices, whenever it wants.
Why it moves the stockThe silent killer of small-caps. Every pop becomes a chance for the company to sell into your buying, capping rallies and bleeding the float.
What it meansA note that converts into stock at a floating discount to market price. The lower the stock goes, the more shares the holder gets.
Why it moves the stockThe most toxic structure in small-caps. It mathematically incentivizes selling, which lowers the price, which mints more shares: a literal spiral. Floats can explode from millions to billions.

05
"Private placement" / PIPE
What it meansThe company sells a block of stock (often with warrants) to private/institutional investors, usually below market.
Why it moves the stockCash now, dilution later. The discount sets a near-term ceiling; attached warrants add a second wave of overhang. A 'raised capital' pop frequently fades as new shares get registered for resale.

06
"Warrant coverage"
What it meansInvestors in a raise also get warrants: the right to buy more shares later at a set exercise price.
Why it moves the stockHidden dilution stacked on the obvious dilution. As the stock nears the exercise price, warrants get exercised and that supply caps upside. '100% warrant coverage' can roughly double the dilution.
Where it shows up
8-K424B10-Q / 10-K
07
"Reverse stock split"
What it meansThe company collapses shares together (e.g. 1-for-10) to lift the share price, often to keep a Nasdaq/NYSE listing above the $1 minimum.
Why it moves the stockChanges nothing about the business, and historically many reverse splits are followed by continued decline, partly because they reset the runway to dilute again. Often a tell of distress, not strength.
Where it shows up
8-KDEF 14AS-1 / S-3
08
"Form 4: insider sale"
What it meansAn officer, director, or 10%+ owner reported buying or selling their own shares.
Why it moves the stockInsiders sell for many reasons, but clustered, open-market selling by multiple insiders (especially after a run-up) is worth respecting. The people with the most information are voting with their wallets. (Code S = open-market sale.)

09
"Cash runway" language in the MD&A
What it meansIn Management's Discussion & Analysis, the company states how long its cash lasts ('sufficient to fund operations for the next…'). Short runway = a raise is coming.
Why it moves the stockWhen a company says it has cash 'into Q[X]' or 'for the next [N] months,' it's effectively pre-announcing the timing of the next dilution. Smart traders mark that date.

"8-K: Item 2.02 & material events"
What it meansThe 8-K is the 'something just happened' filing. Item 2.02 = earnings/results; other items cover deals, executive exits, delistings, and financings.
Why it moves the stockThe fastest-moving document there is, designed to disclose market-moving events promptly. The 8-K often hits EDGAR before the news scroll catches up, so it's the earliest read you can get.

▸ How to read these together
The dangerous combo:going-concern language + short cash runway + an active S-3 shelf = a company that needs money and now has the mechanism to take it from the market. Add a variable-rate convertible and you've got a setup that can grind a chart down for months. None of these is a “sell signal” by itself, but together they tell you what the company is about to do, while everyone else is still watching the candles.
You just learned the 10 phrases. Signal8 reads all 21M+ filings for you.
The second a filing hits EDGAR, Signal8 extracts these signals automatically: dilution risk scores, Form 4 insider patterns, going-concern flags, 13F flow, even politician trades. You can even ask any filing a plain-English question: “Is $TICKER about to dilute?” and get a grounded answer in seconds.
