Welcome to Fix-It Friday, the podcast segment that simplifies financial strategies to help you make smarter decisions hosted by Jonathan Blau, CEO of Fusion Family Wealth. This episode explores one of the most common behavioral investing mistakes: extrapolation. Jonathan explains why recent market performance—whether exceptionally strong or disappointingly weak—doesn't predict what comes next. He breaks down the difference between recognizing patterns and assuming those patterns forecast the future, while highlighting behavioral biases like recency bias, framing bias, denominator neglect, and the misuse of mean reversion. Through real market examples and the fascinating "horse manure crisis" analogy, Jonathan shows why disciplined investors stay focused on long-term compounding instead of trying to predict short-term market movements.
What You’ll Learn:
✅ Why extrapolating past market performance can lead to poor investment decisions.
✅ The difference between mean reversion and short-term market predictions.
✅ How behavioral biases like recency bias and framing bias influence investors.
