We have been reading about how Goldman Sachs has been using high frequency arbitrage trading algorithms to beat the day traders. You just don't
stand a chance against that kind of machine in the short term.
This mornings 30 year treasury yield was up to 4.37% so it looks like at least the long term interest rates are starting to rise. The Fed will be
auctioning off 11 billion more 30 year bonds Thursday. If yields continue to rise that should put some pressure on the equities markets. The GS
arbitrage programs trigger off other investors reactions not future news so the GS computer would not be intuitive enough to dump stock early.
That software was designed by Goldman Sachs to bleed money from the general public, it used decimals before the general public converted
from fractions to decimals. They used bladeserver hardware on a Infiniband (low latency) network, later connected together on a 10Gig E network. The
hardware all talked through a pair of central I/O controllers and was function-built for this purpose, it's crap for anything else. Software on each
server tracks trades on a set of individual stocks, and a number of servers running in parallel are required to track trades on lots of stocks and
beat the general public. So while you're waiting for a certain number to sell, the software predicts this and sells a fraction lower to beat you.
The Goldman Sachs CTO left to start his own company to custom design the hardware for Goldman Sachs, and to try to sell this Million dollar
bladeserver to other companies, most of which wisely chose commodity hardware. The design is obsolete these days, other vendors have leapfrogged far
beyond them.
