Quote from OldTrader:
You're on the right track, but you're too low. The lowest proposal that i have seen so far is .1%. This is the one they have discussed on CNBC. The highest I have seen is .25%.
So at .1% on $53,500, we're talking about $53.50 to buy, and $53.50 to sell. In other words, to make a complete trade would be $107.00. That's 2 points. Now assume you make let's say 3 of those trades per day. That's $321.00 per day. In other words, you gotta make 6 points to break even, BEFORE commission.
If the rate were .25%, we're talking $267.50 per round turn trade. Make 3 of those per day and you're looking at $802.50. How many guys here are making 16 handles a day on one contract?
Effectively, any of these taxes ends the trading business. Period. With that, brokers like IB for instance are going to either go out of business, or have to significantly raise commissions on the long term investors remaining. Expect volume to plummet. Expect software companies to go broke. Etc Etc.
Finally, spreads should widen significantly costing long term investors even more money than just the transaction tax, and increasing volatility. And IPOs have to be priced lower, increasing the cost of capital to new ventures, in order to attract investors facing higher transaction costs and lower liquidity.
Make no mistake, the transaction tax will be the ultimate in stupidity. Yet don't think it can't happen...look at what has already happened.
