Gold was all the rage again last week. But why is it rising, and does anyone really know what it’s worth?

According to the way I calculate momentum, gold has just barely entered the gravity-free zone – where it has the potential to start advancing a lot, with much more fluidity.

And that translates into much higher prices.

Although I normally abhor such popular and trendy positions, the trend-following rules in my asset-allocation models are screaming for a higher weighting than the current 5% in the portfolios that I track in my Strategic Advantage newsletter.

The London Telegraph had an interesting analysis on Thursday, based on an interview with Dylan Grice of Societe Generale SA (OTC ADR: SCGLY). The French analyst said the recent jump

Stocks are lower as the dollar rises and Wall Street digests a week of mixed economic reports

Overseas markets declined. European Central Bank President Jean-Claude Trichet said the ECB plans to start pulling back some of its stimulus programs as the economy begins to recover.

With little U.S. economic news to help sway the market Friday, the dollar is again pressuring stocks. A strengthening dollar drives down foreign demand for commodities, which are often traded in dollars. It also can depress U.S. exports which become more expensive as the dollar rises.

That can hurt the price of energy and materials stocks that are closely tied to commodities and companies with large operations overseas.

A disappointing earnings report from computer maker Dell Inc. is also weighing on the market. Dell said after the market closed Thursday that sales of its computers to big businesses remain sluggish. Its quarterly revenue and profit missed analysts’ expectations.

U.S. stocks tumbled Thursday as concerns about a subdued economic recovery played in the minds of investors.  Safer bets like dollar strengthened and oil prices slumped.  As investors turned to safe havens, Treasury prices rose, sending corresponding yields lower.  Yields on three-month bills, considered one of the safest bets, turned negative for the first time since December.  A Bank of America Merrill Lynch downgrade of semiconductor industry also added to the downward pressure.     

The spike in bond prices came even as the Treasury announced plans to auction a record $118 billion in new notes next week – an auction schedule of $44 billion 2-year notes on Monday, $42 billion 5-year notes Tuesday, and $32 billion 7-year notes on Wednesday.

The Dow, which had plunged as much as 170 points during the session, ended down 93.87 points, or 0.9%, to 10,332.44.  The broader Standard & Poor's 500 index fell 14.90

Stocks are lower as an unexpected drop in home construction raised concerns about the pace of the economy’s recovery

The Commerce Department said construction of homes and apartments fell 10.6 percent in October to an annual rate of 529,000, well below the pace of 600,000 that economists polled by Thomson Reuters had predicted.

Building permits, a key indication for future activity, slid 4 percent to an annual rate of 552,000, also below the rate of 580,000 that analysts had forecast.

There was little reaction to a report that found inflation at the retail level remained tame as rising unemployment, nervous consumers and tight credit keep prices stable.

The Labor Department said consumer prices rose 0.3 percent in October, slightly above the 0.2 percent economists expected. Core inflation, which excludes volatile energy and food prices, rose 0.2 percent, compared to expectations of a 0.1 percent rise.

A report released Tuesday on prices at the wholesale

U.S. stocks closed higher for the second consecutive day, helped by strength in shares of commodity-related companies even as major retailers said they remain cautious ahead of the holiday season.  At the end of a session that lacked conviction, major stock indexes managed to reach their fresh 13-month highs.  A smaller-than-anticipated rise in industrial production also weighed on sentiments.

Waning risk appetites sent gold prices up 20 cents to a fresh all-time high of $1,139.40.  Treasuries rose, pushing corresponding yields lower.  The yield on the benchmark 10-year note slipped to 3.33% from 3.34% late Monday.  Crude prices closed above $79 per barrel.  Copper prices rose to 14-months highs on expectations that China demand will remain robust.

A perpetual decline in the value of the dollar and record low interest rates in the US have driven stocks higher as investors, seeking higher return on their investments, have sought refuge in

U.S. stocks surged to their 13-month highs Monday as a weaker dollar and a rebound in U.S. retail sales reinforced hopes that an economic recovery is indeed underway.  Stocks also got a boost after Fed chairman Ben Bernanke reiterated Fed’s intention to keep interest rates low for an extended period. 

Gold advanced 2% to fresh record highs; and the price of silver jumped 5.9%.  The initial gains in the equity prices followed strength in Asian markets yesterday.  Strength in Asia was partly helped by reports that said Japanese economy grew at its fastest pace in over two years, up 1.2% during the third quarter.  To add to the bullish mood in the region, leaders of the Asia Pacific Economic Cooperation promised to keep the stimulus measures in place.

On Monday, the 30-stock Dow Jones industrial average rose 136.49 points, or 1.33%, to 10,406.96. The broad Standard & Poor's 500-stock

U.S. stocks rose Friday, for their second consecutive weekly advance, as upbeat earnings reports from a number of companies, including Walt Disney and JC Penny, spurred optimism that the economic recovery is gaining momentum.  A dip in the value of dollar, on concerns consumer spending is likely to remain bleak, sent shares of commodity-related companies up. 

On Friday, the 30-stock Dow Jones industrial average rose 73 points, or 0.72%, to 10,270.47. The broad Standard & Poor's 500-stock index was up 6.24 points, or 0.57%, at 1,093.48. The tech-heavy Nasdaq composite index advanced 18.86 points, or 0.88%, to 2,167.88.  For the week the Standard & Poor’s 500 Index jumped 2.3% to 1,093.48.  The Dow average rose 247.05 points, or 2.5%, to 10,270.47, following its 3.2% advance the prior week.

The spike in commodities came after the greenback fell Friday on news that the trade deficit widened more than expected in

A rebounding dollar and persisting worries about the economy kept investors on a wait-and-watch mode and stocks fell broadly as weakness in energy shares, precipitated by reports of flush U.S. reserves, weighed on sentiments.  In a broad based decline, major stock indexes fell about 1% from their 13-month highs. 

The strength in US dollar, based upon its safe-haven appeal, undermined investors' appetites for riskier, high-yielding assets such as equities as upside guidance from DJIA components Wal-Mart and Hewlett-Packard failed to stem the retreat.

The Dow Jones industrial average fell 94 points, or 0.9%, to close at 10,197.47.  The S&P 500 retreated 11 points, or 1%, to close at 1,087.24, after climbing to an intraday high of 1,101.97.  The tech-heavy Nasdaq composite index retreated 18 points, or 0.8%, to settle at 2,149.02.  On the New York Stock Exchange, declining issues outpaced those that advanced in price by a four-to-one margin

With no economic reports on Wednesday and bond markets closed for the Veteran’s Day, Wall Street was witness to a quiet trading session, but stocks managed to inch higher on expectations interest rates would remain at a record low for some time.  Also, strong Chinese manufacturing and retail sales data lifted investor sentiments.  Gold prices touched an all-time high.  

The Dow Jones industrial average, which hit an intraday high of 10,341, advanced 44 points, or 0.4%, to close at 10,291.26. The S&P 500 added 6 points, or 0.5%, to close at 1,098.51, and the tech-laden Nasdaq composite rose 16 points, or 0.7%, to end the day at 2,166.90.  On the New York Stock Exchange, 19 stocks were higher in price for every 11 that declined

Nine of the ten S&P500 industry groups ended in the green, with financials (+1.3%), basic materials (+1.0%) and technology (+0.7%) leading the gainers.  Utilities

A day after the triple-digit rally, Wall Street paused for a breather as investors decided to book profits on a light trading day.  The markets opened lower and then swung between gains and losses amid prevailing caution after a series of disappointing results.  The Dow, nevertheless, managed to tack on 20 points for its fifth straight session gain.

The Standard & Poor's 500 Index shed 0.01%, to 1,093.01 and the technology-laden Nasdaq Composite Index slipped 2.98 points, or 0.14%, to close at 2,151.08.  On the New York Stock Exchange, three stocks declined in price for every two that rose.  Volume was light as only 990 million shares exchanged hands.

Record low interest rates and a sliding dollar have helped stocks in recent months as investors have taken their focus away from some of the persistent worries of the economy.  Also, with the Federal Reserve continuing its highly accommodative monetary
