Quote from Jackofclubs111:
When people profit off of day trades does it not come at the expense of the long positions in the market in general? once again I am asking not arguing. total noobie
There are people who profit off day trades, and there are people who lose. It is a two-sided market.
And because it is a two-sided market of buyers and sellers, the more there are, the closer the matching of prices to buy and sell. Thus, the less volatility, and the more efficient movement of prices.
But as the number of participants in a market declines, bids and offers increase the separation between the buyers and seller, volatility increases, and the cost of each transaction increases because of the increase in spreads.
Regarding your long term investment, when you buy and sell would you rather have few buyers or sellers, or many? Of course you want many, because your price will be filled quickly at a low cost. But if you are unlucky enough to hold a security that has very few buyers (That's happened to me), then you may be unable to sell at a price you want, or at any fair price.
So again, while you may instinctively feel that active trading in your stock is harmful to your position, overall the more people in the market, trading at low costs, is to your advantage.
The same holds true for any marketplace. For example, imagine that you want to sell a car on CraigsList. If there are a lot of buyers looking for your car, there will be good response and everyone will have a good idea of what the car is worth, because there's an active market. The history of pricing on the car will not be volatile. And you're likely to get decent price, because you can count on multiple offers. Conversely, a car that has only a few buyers in the market is likely to have little information on past pricing, so the pricing curve will be volatile. And since there is little demand, the price you receive will not be as efficient or fair as the price for a car with an active market.
Stocks...cars...homes...tulips. Same basic economic fundamentals apply. SO LONG AS THE GOVERNMENT MAINTAINS FREE MARKETS AND THE FREE FLOW OF CAPITAL.
