Earnings Report (E/R)

### The event has a paper trail An earnings release is not just a press release. The numbers reach the market as a Form 8-K under Item 2.02, Results of Operations and Financial Condition, and the full statements follow in the 10-Q, or in the 10-K for the final quarter. Those reports have hard deadlines. The 10-Q is due 40 days after quarter end for large accelerated and accelerated filers and 45 days for everyone else, and the 10-K is due 60, 75 or 90 days after fiscal year end depending on the filer's size. Companies announce the release date ahead of time, and those deadlines bound the window it can fall in. The date is knowable. Nobody should be surprised by an earnings print. ### Why it lands when you are not watching Exchange rules push it there. Under Nasdaq Rule 5250(b)(1), a listed company must notify Nasdaq's MarketWatch department at least ten minutes before publicly announcing material news released between 7:00 a.m. and 8:00 p.m. ET, and must notify before 6:50 a.m. ET for news released outside those hours. Nasdaq's guidance also asks companies not to release material news in the minute straight after the bell, recommending they wait until at least 4:01 p.m. and preferably 4:05 p.m. ET so the official closing price is disseminated first. That is why prints cluster just after the close or before the open, in exactly the sessions where liquidity is thinnest. Regulation FD is the other half of it. A company cannot quietly hand the number to favoured analysts first, it has to reach everyone at once. So what you see is a genuine simultaneous repricing by the whole market, not a slow leak you could have front-run. ### What actually moves the stock Rarely the headline EPS on its own. The number gets priced against expectations, not against last year, and forward guidance is often what does the real damage. A company can beat on both revenue and EPS and still sell off hard because it guided the next quarter lower. Reading "they beat" as "it goes up" is the classic beginner error. ### The part that costs people money Your stop does not save you. The SEC's investor bulletin on stop orders is blunt about it: the stop price is not the guaranteed execution price, and once triggered a stop becomes a market order, which in a fast-moving market can fill materially away from where you set it. A stock that closes at 100 and reopens at 80 does not politely trade through your 95 stop. It fills you at the open. Options are no free pass either. Implied volatility inflates into the print and collapses immediately after it, so a long option can lose value even when the stock moves the way you called. The discipline is the same one you already apply to NFP and CPI on forex. Know the date before you size the position, then decide deliberately whether you want to be exposed across it. Holding through an earnings report because you forgot it was coming is not a strategy.
