Options intelligence
Rule-based, top to bottom.
The market prices every earnings print with an implied move. The stock then makes an actual move. The gap between them is what pays your straddle or drains your credit spread. Here's what that gap looks like across the last eight quarters of a real ticker.
Cyan bars: what the options market priced in. Brass bars: what the stock actually did. The gap is the trade. Median line shows the stock's typical earnings-day move — the number to size to.
The scoring comes straight from the rule-based pre-earnings notebook Maevol runs on. PreDrift-BULL fires when the last 8 quarters show an uptrend into the earnings announcement at least 60% of the time, a same-direction streak of at least 3, and an average pre-move of at least 1.5%.
Change a threshold, change the code. No fitted parameters. No hindsight. The engine is the notebook, running for you on demand.
Not for you if you want someone to text you "buy now." Built for you if you'd rather see the rule and make your own call.
FAQ
Straight answers.
Which tickers can I read?
Any US-listed stock with a few quarters of market-data coverage. Small caps with thin options still show the history; some may not have an implied-move card. ADRs and OTC names are hit-or-miss.
How fresh is the data?
The scanner recomputes nightly around 04:00 UTC. Every US large-cap reporting in the next three weeks gets its EMS, Maevol Ratio, Earn IV Rise, and ranked Strategy refreshed. Per-ticker reads on /app pull the latest close and options chain on demand. Options quotes are delayed, so verify against your live broker before you trade.
Do you tell me what to trade?
No, and that's the point. We show you what the stock has actually done and where the market is pricing the next earnings announcement. The ranked plays are hypotheses, not orders. You keep the call.
Is it really free?
Yes. Three reads a day, tomorrow's earnings in the scanner, and the Saturday email, no card, no catch. The free tier is the trial; use it as long as you like. When you want the full three-week scanner, unlimited reads, filters, and the ranked-strategy column, see Insider pricing.
Can I trust the numbers?
Every rule fires on a fixed, published threshold over the last 8 to 12 earnings announcements. Nothing is hidden. Change a threshold, change the code. (Quotes are delayed; confirm on your broker before trading.)
Can I embed this in my own site?
Yes. The read is iframe-embeddable, with /app as the standalone target. Ask for the snippet and it drops into Kajabi or anywhere else in minutes.
Stop trading earnings blind. See it first.
Type one ticker. See eight quarters, the implied-vs-realized gap, and the ranked plays. Before your next earnings announcement, not after.
