TSC Ratings' Updates: Quanta

Quanta's gross profit margin is rather low at 16.8%, having decreased since the same quarter last year. The net profit margin of 5.2%, however, is above the industry average. Shares are down 52.52% on the year, underperforming the S&P 500, but do not assume that it can now be tagged as cheap and attractive. Based on its current price in relation to its earnings, PWR is still more expensive than most of the other companies in its industry.

Other ratings changes include 3D Systems(TDSC Quote) and Investors Capital(ICH Quote), both downgraded from hold to sell.

Each business day, TheStreet.com Ratings updates its ratings on the stocks it covers. The proprietary ratings model projects a stock's total return potential over a 12-month period, including both price appreciation and dividends. Buy, hold or sell ratings designate how the Ratings group expects these stocks to perform against a general benchmark of the equities market and interest rates.

While the ratings model is quantitative, it uses both subjective and objective elements. For instance, subjective elements include expected equities market returns, future interest rates, implied industry outlook and company earnings forecasts. Objective elements include volatility of past operating revenue, financial strength and company cash flows.

However, the rating does not incorporate all of the factors that can alter a stock's performance. For example, it doesn't always factor in recent corporate or industry events that could affect the stock price, nor does it include recent technology developments and competitive dynamics that may affect the company.

For those reasons, we believe a rating alone cannot tell the whole story, and that it should be part of an investor's overall research.
