The Impact of the Bid-Ask Spread on Trading
The bid-ask spread can have a significant impact on your trading decisions and investment returns. Here's how:
Transaction Costs: The bid-ask spread represents a transaction cost. Every time you buy or sell a stock, you'll pay a price above the bid and receive a lower price than the ask. This can erode your investment returns over time, particularly if you're making frequent trades.
Market Impact: The bid-ask spread can also affect the market impact of your trades. If you're placing a large order, it may cause the stock price to move away from the bid-ask spread, potentially leading to slippage and increased transaction costs.
Liquidity: A smaller bid-ask spread indicates higher liquidity, as there are more buyers and sellers in the market. This can make it easier to enter and exit positions without significantly impacting the stock price.
Case Studies

High-Liquid Stock: Apple Inc. (AAPL) is a highly liquid stock with a small bid-ask spread. As of this writing, the bid-ask spread for AAPL is approximately

1.50. This means that for every 100 you're willing to pay for TSLA, you'll pay101.50, and you'll receive 98.50 when you sell.
In this example, the larger bid-ask spread for TSLA results in higher transaction costs and potentially lower investment returns compared to Apple Inc.
