Why a Stop Loss?

Last updated on June 9, 2023

A stop loss is a valuable tool in stock management as it safeguards your investment against substantial losses. Let’s explore the reasons behind its effectiveness by examining the math before delving into the underlying benefits of this prudent strategy.

Consider a scenario where you purchase 100 shares of a stock at $100, amounting to a total investment of $10,000. Now, suppose the stock’s value begins to decline. By implementing a stop loss at 10%, preferably through an automated system for convenience, you establish an exit point that triggers a sell order when the stock price reaches the predetermined level.

Let’s analyze two cases:

Case 1 (10% stop loss): If the stock drops to $90, your stop loss is activated, resulting in a loss of $1,000 (10% of $10,000). Although the loss is regrettable, it also provides an opportunity to reassess your investment. After conducting thorough research and acquiring knowledge, you may choose to repurchase the stock, taking into account the reasons why this approach could be a prudent strategy for you.

Case 2 (Buy and Hold): Alternatively, if you decide to hold onto the declining stock without a stop loss, and it eventually plummets to $50 (or even $10), selling at this point would result in a loss of $5,000 (or $9,000). These substantial losses can have a significant impact on your portfolio.

When comparing the two cases, the math clearly demonstrates the advantages of employing a stop loss:

In Case 1, with a 10% loss, you only need an 11.1% gain to recover the $1,000 loss, which is a reasonable target.

In Case 2, if the stock drops by 50%, you would require a 100% gain to break even. If it declines all the way to $10, resulting in a 90% loss, you would need to make a staggering 900% return just to return to the breakeven point. Achieving such high returns is often perceived as highly challenging or nearly impossible, making the stop loss strategy more appealing.

Now, let’s discuss the reasons why a stop loss is considered a prudent strategy:

Limiting Losses: The primary purpose of a stop loss order is to establish a predetermined level at which a sell order is automatically triggered. This prevents you from holding onto a declining stock for too long, reducing the likelihood of substantial losses. Setting a stop loss allows for a clear exit point, mitigating the risk of prolonged exposure to a declining stock.

Emotion-free Decision Making: Investing in the stock market can be emotionally challenging, as fear and greed can cloud judgment. A stop loss order removes emotions from the equation by automatically executing the sale when the predetermined price is reached. This prevents impulsive decisions driven by emotions, which often lead to poor investment outcomes.

Risk Management: Stop losses are a vital component of effective risk management. By defining the maximum amount you are willing to lose on an investment, a stop loss allows you to calculate the risk-reward ratio and make informed decisions about your portfolio. Consistently implementing stop losses across your investments helps maintain a disciplined approach to managing risk.

Avoiding Catastrophic Events: Unexpected events, such as negative news about a company or sudden market downturns, can cause stock prices to plummet rapidly. A stop loss order protects you from significant losses during such events. It provides a predefined mechanism to exit a position before the situation worsens, giving you an opportunity to reassess your investment strategy.

Capital Preservation: Successful investing involves not only making profits but also safeguarding your capital. Employing stop losses helps protect your investment capital by minimizing the potential for large drawdowns. This is particularly important for long-term investors seeking steady wealth growth over time.

While stop losses can be beneficial in managing stocks, it is crucial to set them at appropriate levels. Placing a stop loss too close to the current price may trigger premature sales due to short-term fluctuations. Conversely, setting it too far away may expose you to significant losses. Considering the stock’s volatility, historical price movements, your risk tolerance, and investment goals is essential when determining the appropriate stop loss level.

In conclusion, a stop loss is an intelligent tool in stock management that safeguards your investment from substantial losses. It provides a structured approach to limit losses, remove emotions from decision-making, manage risk, avoid catastrophic events, and preserve capital. When implemented correctly, stop losses contribute to a disciplined investment strategy and promote more favorable investment outcomes. A 100% or 900% return on 1 stock is extermely difficult to achieve over many years let alone 1 year. Best to become a Fiscal Investor and avoid the loss of capital and unrealistic returns to make it back.
