If it's mainly noise, why do you care?

What I find most amazing is that the stock market is relatively small, yet people have strong opinions about it while ignoring much larger markets. There's some adage about how if you can't measure it, it doesn't exist or something. If CNN doesn't run a ticker for some market, I guess it doesn't matter.

I care if all my 401(k) alternatives are in markets being parasitized by HFTs who have learned to exploit execution flaws and attack the confidentiality of the order book. Less selfishly, I care if HFTs are diverting society's resources away from the effective producers the market exists to support.

For the same reason you minimize noise to prevent Larsen effects : It is noise that can have feedback effects.
