Does high frequency trading (HFT) punish long-term investment?
Not really. High frequency traders affect mainly short term investors. If everyone invested long-term and traded infrequently, there would be no high frequency trading. For a long term investor, you by at X, hold for several years, and sell at Y. At worst, high frequency trading may affect "X" and "Y" by a few pennies (and the changes may cancel out). For a long term trader that doesn't amount to a "hill of beans" It is other frequent traders that will feel the loss of those "pennies."
