Mixed results for brokerages
The share held by stock companies in the brokerage market is no indicator of profit, with some of those possessing a large market share posting small profits and vice-versa. Profit margins are also quite different.
Stockbroker paradox: The higher the market share, the lower the profit?
Involved in self-trading, some securities companies have a large market share but revenue is quite small and profits are almost non-existent. Since some accept lower brokerage fees and interest rates, investors stand to benefit the most.
