As self-directed retail investing has grown, so has competition for those trading dollars, leading many discount brokers to offer zero commission trades.
Zero commission trades are not good for the markets as they encourage churn and risky short-term trading strategies that lead to price dislocations and speculative bubbles. Evidence indicates that the rise of low and no-commission trading has coincided with a huge increase in retail trading volumes which has led to equity price bubbles which are putting billions of dollars at risk.
I view this as a perfect opportunity for the Federal Government to enter the fray an start charging a $5 per trade tax.
Not only would such a tax encourage thoughtful and longer-term investing, it would be a revenue win.
$5 per trade is an insignificant cost and not a barrier to entry to the retail investor. It will reduce the number of trades, which is a good thing. It will encourage a more conservative investment strategy, which is a good thing. And, it will raise much needed revenue.
The NYSE trades an average of 3.6 billion shares per day. And, due to the rise in retail trading, the average trade is only 200 shares. If the Feds charge $5 per trade they could raise $90 million dollars per day in taxes, from the NYSE ALONE! The NASDAQ moves approximately 4 billion shares a day, so combined revenue from both sources would be over $180 million per day, or about $3.9 billion per month.
Even if this tax leads to 20% fewer trades, the Feds could still raise over $3 billion per month.
So, if the brokerages are willing to offer zero commission trades, then they have created a perfect opportunity for the Feds to raise revenue and limit some risky behavior.
