Understanding the impact of bid-ask spreads on your trading profitability, including tips to minimize their effects.

Introduction

For retail traders, the world of trading can often feel like a high-stakes game where every move counts. You’re not just dealing with numbers and charts; you’re navigating a landscape where every decision can impact your financial future. One critical aspect of this landscape that can make or break your success is the bid-ask spread.

Imagine you’re about to make a trade, your finger hovering over the ‘buy’ button, filled with anticipation and hope. At that moment, the difference between the bid (the highest price a buyer is willing to pay) and the ask (lowest price a seller will accept) is quietly determining how much this trade will truly cost you. This difference, the bid-ask spread, is not just a technicality; it’s a hidden cost that can erode your profits and affect your trading outcomes in ways you might not have realized.

For traders, understanding bid-ask spreads is more than just a necessity — it’s a way to take control of your trading career. It’s the difference between making a profitable trade and watching your potential gains slip away due to hidden costs. This blog is here to help you navigate these waters, offering practical insights and tips to minimize the impact of bid-ask spreads on your trading journey.

Example

Imagine you want to buy shares of Company ABC. The current bid price is $50, and the “ask” price is $50.10. If you place a market order to buy at the ask price, you’ll pay $50.10 per share. Conversely, if you sell at the bid price, you’ll receive $50 per share. The $0.10 difference per share is the bid-ask spread.

The bid-ask spread is crucial in determining the cost of executing trades. Wider spreads mean higher costs, as you effectively pay more to buy and receive less when selling. For high-frequency traders, these costs can accumulate rapidly, eroding profits.

Any veteran trader understands the cost influence. Bid-ask spreads directly influence your trading costs and profitability. Every trade incurs this spread, which can be seen as a hidden cost. The impact is particularly significant for traders who execute many trades, as even small spreads can add up.

The Long Run

Consider a trader who buys 1,000 shares of a stock with a $0.05 bid-ask spread. The immediate cost of this spread is $50 (1,000 shares * $0.05). If the trader makes 20 such trades a month, the total monthly cost from spreads alone would be $1,000. Over a year, this amounts to $12,000, highlighting how these seemingly small costs can significantly impact profitability.

Factors Influencing Bid-Ask Spreads

Market volatility can cause bid-ask spreads to widen. During periods of high volatility, the uncertainty about an asset’s future price increases, prompting market makers to widen spreads to mitigate risk.

Liquidity, or the ease with which an asset can be bought or sold without affecting its price, significantly impacts bid-ask spreads. Highly liquid assets, like major stocks or currency pairs, typically have narrow spreads. Conversely, less liquid assets, like small-cap stocks or exotic currencies, often have wider spreads.

Higher trading volumes generally lead to narrower spreads. When many traders are active, the competition among buyers and sellers increases, which reduces the bid-ask spread. Conversely, low trading volumes can lead to wider spreads as market makers face less competition.

Practical Tips to Minimize Costs

Use Limit Orders: Setting limit orders can help control execution prices and minimize spread costs. Unlike market orders, which execute at the current market price, limit orders allow you to specify the maximum price you’re willing to pay when buying or the minimum price you’re willing to accept when selling. This approach helps avoid the high costs of wide spreads.

Trade During High Liquidity: Timing your trades during periods of high market liquidity can reduce spread costs. Typically, liquidity is higher during regular market hours and when major financial hubs are open. For example, trading major currency pairs during the overlap of London and New York trading sessions can ensure narrower spreads.
