Mammoth Premium is an education platform for selling puts and covered calls. Study real-market examples explained in plain English, explore every outcome at expiration, and practice with pretend money before you ever place a trade.
In English, 简体中文, 繁體中文（台灣） and 繁體中文（香港）, each with its own region’s options terms.
Sample examples for education. Not live data or recommendations.
A narrated tour of the app, recorded with a demo account: made-up tickers and illustrative prices. For education only. Not investment advice.
Examples come from today’s market, refreshed several times during each trading day, so you learn on real prices and real stocks, not textbook cases.
Each example is one card in plain English: the strike, the premium, and how likely the option is to expire out of the money, with every term explained.
Drag a price and see how the trade ends at expiration: the option expires, the shares are assigned, or it closes at a loss.
Try an example in your practice account, or let the account trade the examples automatically, and watch it play out. Decisions about real trades stay yours, at your own broker.
Drag the price and see how a sold put ends at expiration: it expires worthless, the shares are assigned slightly above break-even, or the position shows a loss. No formulas, just a plain-English explanation.
Example: XYZ trades at $100. You sell a put with a $92 strike and collect $1.10 a share, $110 in total, today.
You sell 1 call with a $55 strike.
You collect $85 today ($0.85 × 100 shares). It’s yours to keep, whatever happens next.
Why you get paid: the buyer gets the right to buy your 100 shares at $55 before the option expires. You’re paid for making that promise.
The call expires. You keep your 100 shares and the $85. You can sell another call next time.
Your 100 shares are sold at $55. You keep the $85 too: a $700 gain on the shares ($55 − $48 = $7 × 100) plus $85 = $785 in total.
The trade-off: if LMN shoots past $55, you don’t get that extra rise.
Sample figures for illustration.
Add the shares you hold and explore covered call examples with strikes above your cost, including what happens if the shares are called away and if they aren’t.
Examples on stocks that report earnings before expiration are left out, and you learn why earnings can move a stock sharply.
One example per stock, with an explanation of why several positions on one stock can turn one bad week into several losses.
Your practice account closes trades that start going wrong, so you can see how an exit rule changes the outcome.
Covered call examples flag upcoming ex-dividend dates and explain why shares can be called away early.
Learn the put spread too: the same put, with a cheaper one bought below it, so the most you can lose is known before you start, and far less money is tied up.
Every member gets a practice account. Turn on automatic trading and it works the examples on its own: it sells puts or put spreads, checks them every afternoon, and sells covered calls on any shares it ends up with. Or try any example yourself. Either way, you follow each trade to the end: it expires, the shares are assigned, or it closes early.
Members see how every example turned out, wins and losses, measured the same way every day:
The record shows how the approach behaves in good weeks and bad ones. It doesn’t predict what it will earn.
A high win rate can hide large losses. We always show it next to the full results, so you learn to judge a strategy honestly.
When a number is modeled rather than quoted, you’ll see it marked. You always know what you’re looking at.
Mammoth Premium never connects to your brokerage or places orders. You stay in control of every real trade.
Mammoth Premium is in private beta. Create an account and we’ll review it by hand, usually within a day or two.
