Down Tick

A comprehensive explanation of 'Down Tick'; a sale of security at a price below that of the preceding sale, also referred to as a 'minus tick'.

A “Down Tick,” also known as a “minus tick,” refers to the sale of a security at a price lower than the price at which the security’s last trade was executed. This term is widely used in stock trading and reflects a downward movement in the stock’s price.

Characteristics of a Down Tick

  • Price Movement: A down tick occurs when there’s a decrease in the transaction price relative to the previous sale. For example, if a stock was last traded at $15.00 per share, any subsequent sale at $14.99 or below is considered a down tick.
  • Market Sentiment: The frequency of down ticks can serve as an indicator of bearish market sentiment, suggesting more sellers than buyers at decreasing prices.

Example of a Down Tick

Consider a stock that has been trading at $15 per share. If the next recorded sale price is $14.99 or lower, that transaction will be categorized as a down tick.

Applicability in Modern Trading

Down tick rules have implications for various trading strategies, such as short selling, where a security is sold with the expectation that its price will decline, and it can be repurchased at a lower price, generating profit. Regulations governing short selling often incorporate down tick considerations to mitigate excessive downward pressure on stock prices.

Comparing Up Tick and Down Tick

  • Up Tick: Occurs when a security is sold at a higher price than the previous trade.
  • Down Tick: Occurs when a security is sold at a lower price than the previous trade.
  • Up Tick Rule: A former SEC rule that required every short sale transaction to be executed on an up tick.
  • Bear Market: A market condition characterized by declining prices and prevailing negative sentiment.
