Stock and Option Trading Basics

Aug 16, 2025

Overview

This lecture covered types of stock and option transactions, order types, and how to use stops and limits to manage risk and execute trading strategies. Key distinctions between opening/closing positions, market vs. limit orders, and stop/stop-limit uses were emphasized for exam success.

Position Types & Transactions

  • Two main stock positions: long (buying/owning) and short (selling borrowed securities).
  • Opening purchase: used to establish/add to a long position.
  • Opening sale: used to establish/add to a short position.
  • Closing sale: eliminates/reduces a long position.
  • Closing purchase: eliminates/reduces a short position.
  • "Eliminate or reduce" signals a closing transaction.

Order Types & Placement

  • Only two true order types: market and limit.
  • Market order: instant execution at best available price, no conditions.
  • Limit order: executes at a specified price or better; price is more important than execution speed.
  • Buy limit orders are placed below the current market price.
  • Sell limit orders are placed above the current market price.
  • Use "slobs over bliss" mnemonic: Sell Limits and Buy Stops (above), Buy Limits and Sell Stops (below market).

Stop & Stop-Limit Orders

  • Stop orders activate to become market or limit orders if a trigger price is reached.
  • Sell stop: placed below current market to protect against losses in long stock or establish short positions.
  • Buy stop: placed above current market to protect short positions or buy on breakout.
  • Stop-limit orders add a second condition, making execution less likely but at specified prices.
  • Stops can be used to stop losses, protect profits, or establish positions.

Order Execution Scenarios

  • Trigger price must be met before stop/stop-limit orders become active.
  • Market orders guarantee execution; limit and stop-limit orders may not.
  • More contingencies on an order decrease the likelihood of execution.

Equivalent & Alternative Strategies

  • Selling puts can substitute for buy limit orders as a way to potentially acquire stocks at a lower net price.
  • Buying puts provides downside protection for long positions; buying calls protects short positions.

Special Order Qualifiers & Discretion

  • Additional qualifiers: fill or kill (all now or none), immediate or cancel (partial now, rest canceled), all or none (willing to wait for full order).
  • Discretionary orders require broker authority if deciding action, asset, or amount ("Three As").
  • Market not held orders do not require discretionary authority if the Three As are specified.

Key Terms & Definitions
