Even now, with retail being the most powerful they've ever been in human history, they might be able to squeeze a single, small or mid cap equity (GME being the most famous example) but they cannot move sectors of markets, much less create a generalized bubble in ANY asset class.
Crypto 2017 is the only "bubble" which you might claim was retail-driven (even then, you'd need to provide evidence for such a claim), and even that had institutional money such as Grayscale, high-net-worth speculators, and algotrading from high-net-worth speculators driving the bubble. Not to mention that was a tiny bubble relative to any equity market bubbles.
It's well-known Tech bubble 2001 was driven by investment banks. It's even more well known that the 2008 bubble was driven by investment banks, hedge funds, and derivatives trading. The current $2.5T+ market cap crypto bubble has been formed by large institutional buyers, high net worth individuals, and corporations pumping money.
Dutch Tulips, South Sea Trading Company stocks, 90s Japan were all from institutions or high-net-worth individuals (nobles, royalty, corporations, etc) as well. Your post really couldn't be further away from reality. The historic bond bubbles have all been inflated by institutions and governments. Making a claim that even one bubble, much less "most" bubbles are caused by retail, is an outrageous claim which requires extraordinary evidence that you would need to provide.
FYI, the reason this is happening is that interest rates are so low that people are desperate for yield, and rental yield fits the bill.
There are a lot of benefits:
- professionally managed properties. Most small time landlords are incompetent -- the horror stories you see about landlords being petty or vindictive is from the small time landlord, not the professional manager.
- lower rental prices for properties people want to own. Institutional investors can move funds more quickly to increase rental stock where it is most in demand. Here, too, the yield will fall, which is another way of saying lower rents.
Moreover despite the moral panic by journalists that ordinary households are being priced out, this doesn't actually happen because most institutional investors operate in unconstrained areas, where home prices track construction costs, at most with a small delay. In these areas, an increase in renter demand will result in more property built much more quickly if the institutional investors participate. This actually drives down prices over the long term by increasing supply.
However in constrained areas, this would drive up prices for SFHs. But I thought people weren't supposed to buy SFHs in constrained areas - and institutional investors have been in the multi-unit market for over a century.
But construction costs track home price so this doesn't prevent an unbounded faster than inflation growth.
