Nanex ~ 15-Jul-2013 ~ HFT Saves Buyer over $1 Million!
On July 15, 2013, a buyer of the stock of Guaranty Federal Bancshares Inc.(symbol GFED,
market cap $33M) saved more than $1 Million on a 100 share order! At first, there were
complaints in twitterland about how this poor customer paid way too much ($1,449.99)
for 100 shares of this stock. There were even snarky comments about how an internalizer
only gave them a penny discount below the best ask. But close analysis of the data shows
that just 30 minutes before this trade, the best ask price was a whopping $11,286.24
per share! Which means that High Frequency Trading was able to lower the price of this
100 share trade from $1,128,624 to $1449.99. Wall Streets High Frequency Traders really
went out of their way for this customer.
