Core Viewpoint - The article highlights a significant profit made by a mysterious trader using a long call option strategy, showcasing the potential of leveraging financial instruments for substantial gains in a short period [1]. Group 1: Long Call Option Strategy - The long call option strategy is one of the four basic single-leg strategies in options trading, alongside long put, short call, and short put [3]. - This strategy is employed when there is an expectation of a significant increase in stock price before the option's expiration, with the breakeven point being the strike price plus the option premium [4]. - The advantages of this strategy include theoretically unlimited profit potential as long as the stock price continues to rise, while the maximum loss is limited to the initial premium paid [4]. Group 2: Strategy Implementation Steps - Step 1 involves making a prediction about the stock's price movement and timing, which is crucial before executing the strategy [6]. - Step 2 suggests selecting an appropriate expiration date based on the predicted timeline for the stock's price increase, with a recommendation to allow for a safety margin [6]. - Step 3 advises beginners to choose near-the-money options and to compare the breakeven point with their expected price to ensure a favorable risk-reward scenario [6]. Group 3: Profit and Loss Calculation - The profit is realized when the stock price exceeds the breakeven point, calculated as the strike price plus the premium [7]. - An example illustrates that if the stock price at expiration is below the strike price, the maximum loss equals the premium paid [9]. - Conversely, if the stock price exceeds the breakeven point, the profit can be substantial, as shown in the example where a stock price of 215 results in a profit of 775, yielding a return of 163% [9].
