Final Thoughts on Behavioral Finance and Investor Types
So we made it through all 15 chapters of Behavioral Finance and Investor Types by Michael M. Pompian. Here’s what I think about the whole thing.

In Chapter 24, we go to the floor of the New York Stock Exchange to meet the Specialists. These aren’t just regular traders; they are members who have been given a specific job by the exchange: keep the market for your stocks “fair and orderly.”
This is the chapter where Harris explains how scammers work the stock market. Chapter 12 is about bluffers: traders who trick other people into bad trades so they can profit. If you ever wondered how pump and dump schemes actually function at a mechanical level, this is it.
This is a retelling of Chapter 14 (Conclusions) from “Behavioral Finance for Private Banking” by Thorsten Hens, Enrico G. De Giorgi, and Kremena K. Bachmann (Wiley, 2018).
So we made it. 9 chapters, 17 posts, one brain that’s a little more aware of its own tricks.
This was “Investing Psychology: The Effects of Behavioral Finance on Investment Choice and Bias” by Tim Richards (ISBN: 978-1-118-72219-0, Wiley 2014). And it was worth every page.
This is it. Chapter 15 of Behavioral Finance and Investor Types by Michael M. Pompian is where everything comes together. All those chapters about biases, personality types, asset classes, and financial planning? They were building up to this. The final chapter answers the obvious question: okay, I know my investor type, now what do I actually do with my portfolio?
In Chapter 23, Larry Harris explores one of the biggest financial innovations of the last 50 years: Index Trading. Today, more money moves in index products (like the SPY ETF or S&P 500 futures) than in the individual stocks themselves.
Chapter 11 is about the shady side of trading. Harris introduces order anticipators: people who profit not by knowing what a stock is worth, but by figuring out what other traders are about to do and trading before them. They are parasites. Harris uses that word deliberately. No better prices. No liquidity. They just extract money from other people’s trades.
Theory is nice. But does behavioral finance actually work when real people sit across from real bankers with real money on the table?
We made it. Chapter 9 is the final content chapter of Tim Richards’ “Investing Psychology.” And it’s not really about new ideas. It’s a wrap-up. A summary. A last attempt to remind you what you should have learned, and why most of us will still ignore it.
