Does anybody truly believe that this is a good thing?

The stock market is detached from reality. It creates its own universe. The efficiency we're talking about here is self-referential - it's not efficiency in producing object-level value, it's efficiency in enriching participants of the stock market. Which depends as much on the company itself as it depends on the hype the funds and the shareholders can make around it.

That WSB can tank or revive companies just for teh lulz only shows to demonstrate how the stock market is an universe of its own.




I find people who stand in disbelief of the markets often don't understand how they are working, and/or why they have and societal value.

Skepticism is healthy, but in this case, it's closer to ignorance.

The ability for corporations to go to the open market to secure capital is contingent upon a high liquidity of buyers and sellers present and actively participating.

The market doesn't exist without "primary" buyers and seller acting on behalf of their company to issue new stock (raising capital) or buying back stocks (returning capital (or via dividends)). Between these two types of transactions, there are participants that are constantly estimating the value of these share. If the price of the share deviates too far from what the company thinks it's worth, it will actually trigger one of those two events.

Options are just another more efficient mechanism to make these estimations on a specific timeframe. They allow traders to have a very specific thesis on what is mispriced and place a trade on it.

Without these trades, the market would lack liquidity, and companies would see an increase in their cost of new capital - which is bad for everyone because it means companies wouldn't invest in growth, equipment purchases, new jobs, etc...


The primary value traders provide is liquidity and decreased volatility. There is a fixed need for these two services.

Once you have served every customer the only way to make more money is to take customers away from other competitors, or grow the market as a whole. Traders do not influence the size of the market, they only increase efficiency, so the expectation is that you run into diminishing returns stays.

There is more than enough liquidity in the markets. Any more liquidity is not providing any value.

>Without these trades, the market would lack liquidity, and companies would see an increase in their cost of new capital - which is bad for everyone because it means companies wouldn't invest in growth, equipment purchases, new jobs, etc...

The Fed is already taking care of that. The bigger problem is that there is no reason to invest the Fed money and grow the market.


Increasing efficiency is pretty critical. For the vast majority of markets, there's no such thing as 'serving every customer'. Companies can always serve customers more especially if they can reduce the price.

However it takes capital to do this. It's not just about liquidity, investors basically influence the cost of capital for each company which has a big impact on how many customers each company can serve.


I guess I'm one of the ignorant; I'm still skeptical about derivatives. I get the need for hedging, but when you can construct something mathematically equivalent to a stock without actually putting money into the company, that seems like it could end very badly.


Sorry if my comment came off as critical - probably could have been worded better.

Derivatives are critical even to primary market participants. Farmers looking to secure their pay for future crop deliveries. Banks looking to remove interest rate risk on mortgages they've issued. Shipping companies looking to remove the risk of fuel fluctuations on their future transport costs.

Fluctuations of cost inputs and uncertainty of future revenues can be a company death sentence as they cause cash flow shocks. They have real value to the economy.

Often, they are only possible if there is a liquid market of people willing to take the other side of these transactions. Narrowing the spread between buy/sell prices on these derivative contracts allows more companies to be able to afford them, and that makes many low margin businesses able to exist at all.

Despite all the hate on social media, these markets have material value. ...even if there are these anomalies like this Gamestop incident.

I imagine the SEC is going to shut down that Reddit sub because these types if activities actually destroy liquidity but discouraging short sellers.

Regulation plays an important role in keeping markets running smoothly.


Commodities have to be traded as futures because you cannot move commodities instantaneously. So what you do is you write on a piece of paper (its digital today) that you will provide X amount of commodities for price Y in Z days. You can then sell the contract for the total value of the commodities and when the contract is due you just send the commodity to the holder of the contract.


> it's efficiency in enriching participants of the stock market.

Proponents would say that it is efficienct in funding ideas that are more likely to succeed, with the partecipants in the stock market taking a commission for the transactions.


My point is that "success" on the stock market isn't always a function of doing anything useful in the real world.


This is true and not just true of the stock market. It's true of the economy as a whole. The stock market is just a manifestation of a specific part of the economy.

If inflation is low you can do the dumbest things imaginable and as long as you make your money back you can keep doing the dumb thing over and over again.

If there was decent inflation you would have to have at least some expectation of a future gain because inflation and by extension the increased interest rates would cause your net 0 investments to be a net loss.


My succeed was meant for the companies not the traders. A trader can succeed by being a parassite on the market, a company succeed by doing stuff. Whether there is more/too much parassitism is something I don't know.


the stock market is doing something useful in the real world.

the aggregate success thrown off by the stock market is a measure of the usefulness of the stock market.

participating in that is what enables to stock market to provide its usefulness.

so, yes, success on the stock market is a function of usefulness in the real world.


This is sort of circular, the stock market can also devolve is pure speculation and go full casino, which are generally considered an example of a not-necessarily-net-positive addition to society.


it's not circular, but more to the point, you suggesting that the stock market can devolve (fail) is like saying "brakes on a car can fail, so brakes are stupid." Brakes are not stupid.


I did not say that, I said that just because the people working with stock are getting paid does not mean that the stock market is doing something useful. Parassitism also exists in free markets.

Stretching the brake analogy it would be similar to noting that just because you are pressing more your brake pedal it does not mean that your car is slowing down faster, sometimes you need an ABS
