Case study: Coca-Cola, 1993

Get paid to wait, like Warren Buffett

In 1993, Warren Buffett collected $7.5 million by agreeing to buy Coca-Cola shares at a price he was willing to pay. Kiếm Tiền Chợ teaches you how this strategy works on a smaller scale.

  1. 1

    Choose a stock and your buying price

    Buffett agreed to buy 5 million Coca-Cola shares for $35 each if the contract required him to buy before a set deadline.

    Think of it as saying: “I’m willing to buy this stock for $35, and I’ll get paid for making that commitment.”

  2. 2

    Get paid upfront for that commitment

    The buyers paid him $7.5 million for the right to sell their shares to him at $35. That protection works much like insurance against a falling stock price.

    His commitment meant he could be required to spend $175 million buying the shares. For a beginner using this strategy, that means setting aside enough cash to cover the purchase.

  3. 3

    Keep the payment, with two possible outcomes

    If the contract expires without a purchase: you keep the upfront payment. That’s what happened in Buffett’s example.

    If you’re required to buy: you buy the shares at your agreed price and still keep the upfront payment.

    The risk: the stock can keep falling after you buy.

A trader's experience. A software builder's approach.

After nearly a decade trading US stocks, Duc set out to make the approach he uses easy to understand and follow.

“Could I make the process simple enough for someone without a finance background to follow?”

The experience

“I have traded US stocks for close to ten years. It gave me the freedom to work and travel from anywhere. As a day trader I had good months, sometimes excellent ones, only to give the gains back. Being right often was not enough when a few losses could outweigh the wins.”

The turning point

“It came when I moved from buying options to selling them. As a buyer I needed direction, timing and the size of the move to line up, while time worked against me. As a seller I collect a premium in exchange for accepting an obligation. Buffett's Coca-Cola trade is what made it click.”

The tools today

“Our software and AI-assisted screening pick out contracts to sell each morning. I spend about five minutes placing my trade, then get on with my day. It is the simplest, most consistent approach I have used, and that is why I want to share it.”

Questions people ask first

All questions
What exactly am I selling?
A promise. You agree to buy 100 shares of a company at a set price, any time before a set date, and you are paid a fee (the premium) up front for agreeing. The trade is called a cash-secured put because you keep the cash to buy those shares ready in your account.
What happens if the price falls below my promised price?
You buy the 100 shares at the price you promised, and you keep the premium, so your real cost is the promised price minus the premium. The shares may be worth less than that on the day, and that loss is real. This is why we only suggest companies you would be content to own, in a size your account can carry.
How much money do I need to start?
One contract covers 100 shares, so the cash you set aside is the promised price × 100. In the Sep 17 snapshot above that ran from $3,700 (SMCI) to $52,000 (AMD). The planner shows which trades fit your account.
Is this guaranteed income?
No. The record above includes a losing trade, and there will be more. Rates on this page are averages or targets, not promises, and money invested can fall in value.
