I wonder  that would be the effect on quick-time stock sales if there was a transaction tax on each stock sale equal to $1/number of seconds the security has been held. If you hold a stock for 1 second it is a $1 tax. If you hold a stock for 1/100000 of a second it is a $100,000 tax. If you hold a stock for 10 seconds it is a dime tax.

This would be a per stock tax with the proceeds going to the SEC for enforcement.
