About Howl: Stock & Insider Alerts
Howl reads the SEC filings for the stocks you follow and tells you when one is worth your attention. Public companies disclose everything. 8-Ks, quarterly reports, insider trades, earnings. Almost nobody reads them. Howl checks for new filings on your watchlist every five minutes during market hours and turns the ones that count into plain English. When a CEO buys stock, when a company files an 8-K, when earnings land, you get a push and a short explanation of what happened. INSIDER TRADES WITHOUT THE NOISE Most insider filings are stock grants, tax withholdings and pre-scheduled sales. Howl filters those out and keeps the buys and sells that carry a signal, scaled to the size of the company. A large purchase at a small company gets flagged. The same dollar amount at a trillion-dollar company does not. Each stock also gets an insider sentiment read, so you can see when several executives are buying at once. EARNINGS, EXPLAINED Shortly after a company reports, Howl reads the press release and tells you whether it beat or missed, what changed in guidance, and what to watch next quarter. Every past quarter sits on the stock page next to what analysts expected. CONGRESS TRADES Members of Congress must disclose every stock trade. Howl collects those filings for 17 politicians, scores each one's disclosed buys against the S&P 500 from the day they were filed, and flags when someone trades a sector their own committee oversees. WHAT THE BIG FUNDS HOLD 23 notable investors, from Warren Buffett to Bill Ackman, file their portfolios every quarter. See what each of them holds, what they bought and sold, and which stocks the most of them bought last quarter. EVERY STOCK, IN PLAIN ENGLISH Open any stock for a clear read on what is happening and why. See how the business makes money, segment by segment, with revenue figures from its own annual and quarterly reports. A valuation dial shows how much growth today's price assumes, and lets you test your own view of what a share is worth. YOUR WEEK, BEFORE IT HAPPENS Earnings dates, Fed decisions and economic releases for the stocks you follow, plus a daily market brief that leads with the bottom line. No hype, no hot takes, no jargon. Just the source documents, made readable. Free on iPhone and iPad.
