Current Dividend Yield
Annual dividend divided by current market price.
Changes constantly as stock prices fluctuate.
Useful for comparing investments at today's prices.
Yield on Cost (YOC)
Annual dividend divided by your original purchase price.
Personal metric that reflects your actual income vs investment.
Can be very high for long-held positions with dividend growth.
Which Metric to Use?
Use current yield when comparing new investment opportunities.
Use YOC to track your personal return on investment.
High YOC can be satisfying but shouldn't prevent selling if fundamentals deteriorate.
