You could limit this tax to short term trades so it wouldn't penalize long term buy and hold investors.
Yes, the simplest solution is a 0.1 % tax on short-term trades. It's actually pretty strange that practically everything else one buys is taxed by the government but not shares. No surprise that we get all this useless and dangerous high frequency trading, and an obscenely large financial sector.

Why do you feel that raising the bid/ask spread to $0.25 will prevent wildly oscillatory behavior? If anything, it will probably increase strange behavior. If you want to buy shares, you'll either need to pay a largish premium or else you'll need to wait a while. Fun fact: for the most part, prices have stabilized and spreads have narrowed as HFT has entered the game.
If everyone, even the huge institutional players, has to deal with non-zero bid/ask spreads, it does reduce incentive to spend a lot of effort exploiting tiny arbitrage opportunities with huge-volume trades, which could stabilize things overall. Admittedly, it's something economists disagree on.

#341) Acquiring a company worth $100mm pre-tax?
- After tax, the cost just went up to $125mm.
2) Global competition
- Foreign exchanges would under-cut domestic exchanges, attracting many US based companies to list there and if the US attempted to tax foreign transactions by domestic persons, then foreign investors would end up with an unfair advantage.
The idea of disincentivising short-term investments is a good one. Changes to existing capital gains rules or a progressive per transaction tax may be more feasible though.

#35You realize that, as much or as little sense as this makes, it's roughly what every voter wants to see happen?

#36Why tax 25 cents on a $80,000 stock (like whatever Berkshire-Hathaway is now), and 25 cents on a "penny dreadful"? I understand the point of view - tax away high-frequency trading, but have we really thought things through? Obviously not.
FTA: "You could reduce the tax per share for stocks under $5 dollars to 5 cents. But I would leave it at 5 cents even for stocks priced at pennies per share or less."

#37And at what cost? Driving businesses out of the US? Severely lowering the attractiveness of listing a company on the US stock exchange? A billion other unforeseen consequences which neither I nor he is smart enough to see?

Arbitrage-exploiters do the worthwhile task of removing arbitrage. Putting arbitrage back into the market, visible to everybody but which everybody will sit on their hands until it becomes worth the 25 cent fee to exploit, seems like a way to create more instability.

It can add instability though, if the arbitrage-exploiting is too large a proportion of the market. If 95%+ of trades are trades based on statistical market patterns, which are themselves created by those same 95%+ of trades, you get weird feedback loops that have more to do with chaotic systems and attractors than with supply or demand.

#40It's easy to suggest taxes that don't affect you personally.
