Is This Something To Be Worried About?

A single mysterious computer program that placed orders — and then subsequently canceled them — made up 4 percent of all quote traffic in the U.S. stock market last week, according to the top tracker of high-frequency trading activity. The motive of the algorithm is still unclear.

The program placed orders in 25-millisecond bursts involving about 500 stocks, according to Nanex, a market data firm. The algorithm never executed a single trade, and it abruptly ended at about 10:30 a.m. Friday.

I do believe the market is being manipulated for sure. There is no way it can be so strong with all the news that I read and hear. I know that the returns for any investment at the banking level is basically zero so people are still trying to invest to gain some return on their money. I just don't trust any of it at all.

Maybe one of my smarter readers can weigh in with a more intelligent answer or thought on this?
