Short Selling and Day Trading Lecture Notes

Introduction to Short Selling

• Definition: Short selling is the process of selling a stock and buying it back at a lower price.
  • Opposite of buying low and selling high.
  • Allows trading in both market directions.
• Market Bias: Market is generally long-biased due to regulations and structure.

Types of Trading Accounts

• Cash Account:
  • Funded with cash, trades require settlement periods (usually 3 days).
• Margin Account:
  • Allows immediate trading by borrowing funds from the broker.
  • Necessary for short selling and frequent trading.

Short Selling Mechanics

• Negative Share Balance:
  • Selling shares you don’t own, resulting in a negative share position.
  • Must buy back shares to "cover" the position.
• Margin Requirements:
  • Essential for day traders to increase trade volume.

Short Selling Strategies

• Look for stocks extended to the upside.
• Example: Trading Autodesk with consecutive green candles, anticipating a reversal.
• Risk: Losses can be unlimited if stock price increases significantly during a short.

Risks and Limitations of Short Selling

• Unlimited Loss Potential: Unlike long positions, losses in shorts can be limitless.
• Days to Cover:
  • Mandatory period after which you must cover your short position.
  • Increases risk compared to long positions.

Short Interest and Short Squeezes

• Short Interest: Proportion of shares held short against the total float.
• Short Squeeze: Rapid stock price increase forcing short sellers to cover by buying.
  • Causes parabolic price moves (e.g., DRYS, HMNY).

Short Sale Restrictions

• Uptick Rule: Restricts short selling on stocks dropping by 10% or more.
• Market Bias: No restrictions on buying; short sale restrictions favor long traders.
