From a gpt with an eli5 prompt if it’s helpful. Think of a stock option like a special ticket you can buy for a toy store. This ticket isn't for buying a toy right now, but it gives you a choice to buy a specific toy at a specific price, let's say $10, anytime in the next month. Buying the Ticket (Option): You pay a little money to get this special ticket. This is like buying an option in the stock market. Deciding to Buy the Toy (Exercising the Option): Let's say the toy you like becomes very popular and its price goes up to $15 in the store. But since you have the ticket, you can still buy it for $10. This is a good deal! In stock options, if the stock price goes up higher than your special price (strike price), you can make a profit. Or Maybe Not Buying the Toy (Letting the Option Expire): What if the toy isn’t that popular and its price drops to $5? Then, you wouldn’t use your ticket because it says you have to pay $10. So, you just don’t use the ticket, but you did spend a little money buying it. In stock options, if the price goes down, you don’t have to buy the stock, but you lose the money you paid for the ticket. Answer from ZiiC on reddit.com

r/stocks on Reddit: I have no idea how options work can someone explain them in layman's terms?
December 22, 2023 -

So I've been interested in delving into options trading but I don't really understand how they work. I was wondering if someone could help explain them to me. I've included a prompt below that made me realize I don't really know what I'm doing.

"You're paying $42.00 for the right to sell 200 shares of XXXX for $4.50 each by December 22. If shares of XXXX aren't $4.50 or lower on December 22, these options will expire worthless."

So based on this prompt, do I need to have 200 shares to actually make money from this option? Can i just sell the option? How do i calculate the gains from the option? if I sell the option, am I just selling the contract to someone else that had 200 shares that they want to sell?

Ive tried looking online for some good sources to explain how this works, and if anyone has any links to a "guide to options for legit idiots" I'd love to check it out. Thank you.

As everyone has already said options are complicated. I’m not even going to go into the “Greeks”, but here is the simplest way of how options work. One option represents 100 shares of a given stock. Options have a strike price and an expiration date. The strike price is the price that the option can be bought or sold at. American options allow you to exercise those options any time before and up to the expiration date. Two types of options: call options (calls) and put options (puts). A call option gives you the OPTION to BUY a stock at the strike price on or before the expiration date. Buying a call is a bullish position as you are anticipating the price to go up. In contrast a put option gives you the option to SELL a stock at the strike price on or before the expiration date. Put options are a bearish position as you are anticipating the price to go down. Most options are traded or left to expire and not actually exercised. Options can be used as vehicles to hedge your positions, but again most are used to trade. As with stocks you can buy an option or you can sell (write) an option. You need to have a good understanding of options before you write any as this is much riskier especially in terms of capital requirements. You can buy options OTM(out the money), ITM(in the money), or ATM(at the money). For call options OTM options would mean the strike price is above the last price of the underlying security, ITM would mean the strike price is below the last price and ATM would mean the strike price and the last price are the same. The inverse is true for put options. Let’s move to an example. Stock XYZ is trading at $100. You are bullish and buy one OTM call option with a strike price of $105 that is set to expire a month from now. You buy the option for $1.00 and since one option represents 100 shares this trade costs you $100. At the day of expiration your break even price would be $106 meaning in order to break even on that day you need the stock to be trading at or above $106. Now let’s say you’re bearish. You could buy a put option giving you the option to sell at the strike price at some time in the future, or you could write a call option. Writing a call option means you would sell someone an option and collect the premium hoping that the option would be worthless at expiration. In the previous example if you were the one selling the call option then you would collect that $100 and then as long as the individual who bought it was OTM and chose not to exercise by expiration then you would keep that premium. However, selling call options is risky if you do not own the underlying security. Selling a call means that should the person who bought that call exercise it you are obligated to sell them that security at the strike price. If you don’t own that security you have now entered yourself into a short position as you would have to borrow shares to cover your obligation to that contract, but you would now owe those shares back to your broker. Similarly selling a put is a bullish position meaning if the individual you sold it to chose to exercise it you would be obligated to buy those shares at the strike price. Whether selling calls or options though you still keep the premium. And keep in mind that every day options lose a little value as they get closer to their expiration date (taking the actual movement of the stock price out of the equation). That’s where the “theta gang” comes from. Anyways, that’s just a general overview, but hope this helps. I’d definitely recommend doing some more research into options though. They are a whole different animal from stocks.

What are good stocks to trade options (just doing research)
There's no answer for this, though usually higher volume helps so that your buys/sells have higher chances of going through. You can do anything with options. Stocks that are collapsing are good for options. Stocks that are skyrocketing are good for options. Stocks that aren't moving at all are good for options. All three can also be terrible for options. Whether a stock is "good" for trading options depends on your strategies and knowledge level. Anyone can make or lose money trading options for any stock. If you're asking this, then you're still not sure what options even are; focus on learning what they are before worrying about which stocks you should trade. Not understanding options means that you could be handed the "best" stock to trade for the day and you'd still bankrupt yourself. More on reddit.com

Option traders! Tell me what a day in your life is!!
This is asked once in a while, but I'll answer again since it has been a bit. I've been trading options "full time" for going on about 7ish years. I make full time in quotes as I spend maybe 15 to 30 minutes a day on actual trading activities, but use trading income as an income stream. To me, trading is freedom as I can earn a decent income from my capital, but without having to have a job and boss, or punch in to a clock, and whatever. It is running a small business with myself as the sole employee. With mobile devices I can watch or manage my trades from most anywhere, even the golf course. ;-D The strategy I trade is the wheel as it has just worked well for me for many years. The hard work and time is doing research and due diligence and ongoing review of the stocks to be traded which can take several hours a week based on the size of the account and the number being tracked. I tend to do this in the evening or on Saturday morning, but this takes a lot more time then entering, managing and closing trades. Personally I love trading and think it is still fun after all of these years. I enjoy it so much I spend more time on reddit (than I should) helping other traders get started so they can trade as well. I treat trading like the business it is and the wheel is very boring compared to other strategies that are higher risk and often make less money, or even lose money. If you want to be a serious trader who makes a reasonably reliable return and income, then expect it will not be exciting . . . In fact, the more boring the better as that means trades are closing over and over to make small but lower risk profits. Returns are very individual and based on the trader, but also how the market is. Most new traders report making about 10% to 15% per year in returns, some lose money the first year or two, and those with good knowledge and experience can make more. I've had a range of a 12% annual return to a 50%+ return in 2021. I would not try to inspire you as much as prepare you for what is likely to be a long journey until you have reasonably reliable success. Expect it will take as long as 6 months of learning and practicing to understand how it all works and to build out your trading plan, then up to 2 years until you have it all dialed in. Based on your annual average gains you will find it will take a substantial amount of capital to make a decent income. If you'd like to make around $1K per week, or $52K per year, and have an exceptional annual of 20%, then it will require about a $260,000 in capital. While accounts can be built over time, you can do the math on how long it will take. If you want to explore this then I'd suggest opening a paper trading account on a full featured broker like TOS to get started learning - https://tickertape.tdameritrade.com/tools/papermoney-stock-market-simulator-16834 Something to note is that paper trading is a sim and is not an accurate representation of real money trading, but can give you a taste for you to see what lies before you if you want to trade. This is the wheel plan I posted over 5 years ago. I still trade it and have kept up to date - https://www.reddit.com/r/options/comments/a36k4j/the_wheel_aka_triple_income_strategy_explained/ Feel free to ask questions and I'll answer if I can. -Scot More on reddit.com

Unlike buying a share of stock where you own a piece of a company, an options contract is based on where you think that stock's price is headed within a specific timeframe. When you trade an option, you are essentially entering an agreement: As a buyer, you pay a "premium" for the right to buy or sell the asset at a predetermined price (the strike price) before or when the contract expires.
