Stock trading in and of itself doesn't produce anything at all.
That's a bit too broad. While it is true that stock trading per se does not produce a tangible product, one that can be consumed or held in one's hand, there are other aspects of any marketplace that differentiate themselves from such products.
First a clarification: The tone of your remarks suggest that by "stock trading," you refer to day traders and others who take speculative positions in stocks, hoping to earn short-term profits from subsequent moves in their prices. The determining characteristics then seems to be "short-term" and "speculative" as opposed to "long-term," which is more typically associated with "investment" rather than "speculation." Does that sound about right?
Stock trading, as I infer your comment to mean, does one very important thing: it adds to the depth, breadth and liquidity of the overall market. These are non-trivial aspects of any marketplace, not just stocks. In economic terms, they have been referred to as "the holy trinity." When the time comes for a pension fund to invest the proceeds of this year's allocation from its members, for a corporation to float its initial public offering (or an existing corporation to issue new shares), or for a corporation to buy back some of its shares, this depth, breadth and liquidity are the characteristics that permit these actions to take place without severely disrupting the markets.
Who are "stock traders?" There are two general classes: exchange-designated market makers, and non-exchange designated market makers. Exchange-designated market makers are those whose license or membership requirements mandate that they provide continuous bids and offers for the securities for which they are the designated market makers. Market making schemes vary from exchange to exchange, but the one underlying characteristic is that they risk their own capital (or that of their employer) while fulfilling their function. Also in the exchange-affiliated group are exchange members who trade strictly for their own account and those who execute orders for others.
The other general class consists of non-exchange affiliated traders. These sound more like the type of trader to which you refer. They tend to take short-term positions, sometimes for fractions of an hour, seeking short-term profits, risking their own capital while doing so. Clearly, their activities add to market liquidity.
Regardless of exchange-affiliated or not, these activities add to the depth, breadth and liquidity of the markets, thus performing an economic service. True, this activity doesn't result in something physical that can be held, manipulated or consumed, but it is economically valuable nonetheless.
Note: I don't mean to insult anyone's knowledge level with these basics. You (and some others) may be well aware of all that I've written, but I have no way of knowing who does and who doesn't, so I proceeded from the assumption that basics would be illustrative to most.
