Dan Amoss talking about the incoming risks to passive investments.
These funds don’t try to beat the market. They are the market. They buy stocks based on their size in the index, no questions asked.
On the surface, this passive revolution appears brilliant. Passive funds are cheap, with management fees close to zero. They have performed well in the past. And they require no effort.
But like so many financial innovations that seem too good to be true, this one comes with hidden risks that few investors understand.
According to Mike Green, chief strategist at Simplify Asset Management, this passive revolution has created unintended side effects that could end in disaster.
Green calls passive investing the “giant mindless robot.”
Why?
Because when new money flows into index funds, it doesn’t sit on the sidelines. This money flow is not completely isolated from the index it tracks. Rather, it buys stocks immediately. And not just any stocks. It allocates the largest share of incremental purchases to the largest stocks (like Apple, Microsoft, Nvidia, and Amazon) because those names dominate the index.
This creates what economists call a “price-insensitive buyer” – the most dangerous type of market participant. The money flows in, the big stocks get bigger, and the index rises. That rise draws in more money, which buys more shares, pushing prices even higher.
It’s momentum on autopilot.
Here’s where Goodhart’s Law reveals the fundamental problem. The index has become the target of trillions of dollars in retirement accounts, pensions, and ETF flows. It’s no longer as good a measure of economic strength as it once was!
The post is written from a US perspective, but I believe something similar will play out in India over the coming decades.
