Very, very briefly...Could you elaborate a bit more on these reservations and the problems you believe stock markets cause?
Direct purchase of stock in a company is an investment with an evaluated risk profile - the individual person buying the shares is knowingly and intentionally trading free capital now on a risky venture for a potentially higher future payout. While it's always possible for individuals to make poor choices and bad investments, it generally holds true that the expected return is correlated with the riskiness of the entity in which partial ownership shares are being purchased.
When it gets to the stock market, however, those shares frequently get divorced from the underlying evaluation of the risk and reward associated with the company. Shares get treated as commodities in their own right, and traded back and forth in ways that frequently mask the underlying risk. They get rolled into mutual funds, or industry aggregations where the high risk associated with Company A is masked by the safety of Company B. Because the stock is all commingled, the risk gets reported on a presumed "average" basis. This can artificially prop-up A and artificially harm B. It ends up spreading risk not solely among the various shareholders, but also between the companies whose stocks are being aggregated.
It also creates a middle-man market for the trading of those shares, and then you get day traders and various other trading firms who then make money with little to no risk of their own by facilitating the aggregated stock trades of people who have no actual knowledge or understanding of the underlying value or lack. So now there's an entity skimming value - not from the actual value of the companies that are represented by the shares, but from the act of trading other people's money.
The secondary market is even worse, in my view. That's the realm of options, puts, shorts, etc. In that case, it's not even necessarily the actual shares being traded, it's entirely nebulous concepts of future possibilities. On paper, those secondary mechanisms can serve to hedge risk - but that really only holds true if it's partnered with actual direct share purchases and a very comprehensive understanding of the portfolio of stock that's already held. In reality it's turned into something tantamount to betting. Hedge funds end up betting with other people's money.
