NEW YORK ( TheStreet) -- ValuEngine covers more than 8,000 stocks among 16 sectors. My asset allocation recommendations are based on the distribution of the number of stocks with buy ratings compared to the number of stocks with sell ratings for each sector. Sectors with a high distribution of buy rated stocks are rated overweight, while sectors with a high distribution of sell rated stocks are rated underweight.Aerospace has 48 stocks or 64.0% of the 75 stocks in this sector rated strong sell or sell, the sector gets an underweight rating. Auto-Tires-Trucks has 67 stocks or 69.8% of the 96 stocks in this sector rated strong sell or sell, the sector gets an 'avoid source of funds' rating. On June 24 I wrote Toyota, Volvo Headline Downgrades to Sell which is when I explained this rating for this sector. Basic Materials has 199 stocks or 48.4% of the 411 stocks in this sector rated strong sell or sell, the sector gets an underweight rating. On June 25 I wrote Gold Stocks Are Extremely Undervalued where I provided buy-and-trade levels for several gold mining stocks with hold ratings. Business Services has 99 stocks or 41.4% of the 239 stocks in this sector rated strong buy or buy, the sector gets an overweight rating. Last Friday Accenture ( ACN) ($72.10) offered a disappointing sales forecast pre-market and the stock was taken to the woodshed with an open below its 200-day simple moving average at $73.23, closing down 8.24% on the day. The price weakness was enough to upgrade the stock to buy from hold. My annual value level is $64.30 with quarterly and semiannual pivots at $70.01 and $72.61 and weekly risky level at $78.68. AAPL) ($409.22) was upgraded to buy from hold. The prior ratings change was on May 6 when the stock was downgraded to hold from buy at $458.80.
