The S&P 500 Composite (SPX, 1,285.09) rose 0.50 points or 0.04% on Friday, October 28, 2011. SPX rose 3.78% for the week.

The robot, trading algorithms that trade 24 hours around the clock had quite a week. All of the U.S. stock market gain last week occurred on overnight gaps in reaction to the news out of Europe and, to a lesser extent, China.

I have noticed for some years now that front-running the U.S. open increasingly is a winning way to game the market. That and high-frequency trading algorithms that can read, interpret, and react to momentum, price anomalies, and news in a millisecond or two–well before humans can perceive that something just happened. Now if we only had a multimillion dollar trading infrastructure to take advantage of this insight…

A graph of cumulative close minus open prices for the SPDR S&P 500 ETF (SPY: 128.60) is actually lower now than it was a week ago. That implies net selling pressure during the regular New York trading session from 9:30 a.m. to 4:00 p.m. (The SPX cash index does not offer a true open price, so we cannot use it for any indicators that depend on an accurate open price.) If a day trader bought on the open and sold on the close each day, he would have lost money.

Some say that the 19-trading day bounce has left the stock market at its most extreme overbought level of the past year. CNBC reports that a Birinyi Associates model has reached an “absolute sell price”.

In my experience, technical indicators probing into overbought territory do not necessarily imply an immediate price decline. It does suggest a vulnerability, however, once the upside momentum has dissipated.

Secondary Reactions are significant counter-trend corrections against the Primary Tide that can last several weeks to several months and recover a substantial proportion of the previous losses.

Longer-term indicators still are far from confirming any change in the major Primary Tide trend. For example, 50-day SMAs are well below 200-day SMAs for most stocks and indexes.

The Dow Theory signaled a Primary Tide Bear Market on 8/2/11, when both Averages closed below their closing price lows of the previous 11 months. This Bear Market was confirmed on 10/3/11 by lower closing price lows for both Averages. Both Averages would have to close above their closing price highs for the year to indicate a “Turn in the Tide”.

The 50-day SMA remains below the 200-day SMA, indicating a neutral trend. GDX/GLD fell below 29-month lows on 8/8/11, reconfirming a bearish major trend for the long term. Investors still prefer Gold bullion over Gold Miners.

Silver, iShares Silver Trust ETF (SLV) price rose above the highs of the previous 5 weeks on 10/27/11, possibly confirming an end of a downside short-term correction. Longer term, SLV price broke down below the lows of the previous 7 months on 9/26/11, which confirmed a bearish major trend for the long term. SLV fell below its 50-day SMA on 9/19/11, fell below its 200-day SMA on 9/22/11, and remains bearishly below both SMAs. Support 27.41, 26.03, and 24.44.

Longer term, the SLV/GLD Ratio broke down below the lows of the previous 11 months on 9/30/11, reconfirming a bearish major trend. SLV/GLD has been mostly weak since peaking on 4/28/11. This means investors prefer Gold over Silver.

Copper, iPath DJ-UBS Copper TR Sub-Index ETN (JJC) price rose above the highs of the previous 5 weeks on 10/27/11, confirming a short-term upside correction. Longer term, JJC broke down below the lows of the previous 14 months on 10/5/11, confirming a bearish major trend. Major trend weakness in Copper suggests serious concerns about the economic outlook.
