The following ratings changes were generated on Monday, Nov. 24.

We've downgraded

Enbridge

(ENB) - Get Report

, which engages in the transportation anddistribution of crude oil and natural gas, from buy to hold. Strengths include its robust revenue growth, impressive record of earnings-per-share growth and compelling growth in net income. However, as a counter to these strengths, we also find weaknesses including generally poor debt management, poor profit margins and weak operating cash flow.

Enbridge's revenue leaped by 65.8% since the same quarter a year ago, exceeding the industry average of 30.1% growth and boosting EPS in the most recent quarter compared with the same quarter a year ago. The company has demonstrated a pattern of positive earnings per share growth over the past two years. During the past fiscal year, it increased its bottom line by earning $1.96 vs. $1.79 in the prior year. Current return on equity exceeded its ROE from the same quarter one year prior, a clear sign of strength within the company. On the basis of ROE, Enbridge has underperformed the oil, gas and consumable fuels industry and outperformed the

S&P 500

.

Net operating cash flow has significantly decreased to -$131.80 million, or 65.99% when compared with the same quarter last year. In addition, when compared with the industry average, the firm's growth rate is much lower. Currently the debt-to-equity ratio of 1.75 is quite high overall and when compared to the industry average, suggesting that the current management of debt levels should be re-evaluated

We've downgraded

St. Joe

(JOE) - Get Report

, which operates as a real estate development company in Florida, from hold to sell, driven by its feeble growth in its earnings per share, deteriorating net income and decline in the stock price during the past year.

St. Joe has experienced a steep decline in earnings per share in the most recent quarter in comparison with its performance from the same quarter a year ago. Earnings per share have declined over the last two years, and we anticipate that this should continue in the coming year. During the past fiscal year, St. Joe reported lower earnings of 14 cents vs. 20 cents in the prior year. For the next year, the market is expecting a contraction of 178.6% in earnings to -11 cents. Net income has significantly decreased by 182% when compared with the same quarter a year ago, falling from -$6.81 million to -$19.20 million and underperforming both the S&P 500 and the real estate management and development industry.

Revenue plummeted by 57.6% since the same quarter one year ago, underperforming the industry average of 33.5%. EPS also decreased. On the basis of return on equity, St. Joe. Underperformed the industry average and the S&P 500. Shares are down 18.4% on the year, reflecting the market's overall decline (which was actually deeper) and the decline in the company's EPS. The fact that the stock has come down in price over the past year should not necessarily be interpreted as a negative; it could be one of the factors that may help make the stock attractive down the road. Right now, however, we believe that it is too soon to buy.

We've downgraded

Magellan Midstream Holdings

( MGG), which engages in the transportation, storage, and distribution of refined petroleum products, from hold to sell, driven by its generally disappointing historical performance in the stock itself and generally weak debt management.

The debt-to-equity ratio is very high at 15.61 and currently higher than the industry average, implying very poor management of debt levels within the company. The company also manages to maintain a quick ratio of 0.40, which clearly demonstrates the inability to cover short-term cash needs. Net income increased by 25% when compared with the same quarter a year ago, from $14.11 million to $17.65 million, underperforming the oil, gas and consumable fuels industry but outperforming the S&P 500. Revenue dropped by 9%, but EPS increased. Magellan's gross profit margin of 41.4% is strong, having increased from the same quarter last year. The net profit margin of 6%, however, trails the industry average.

Shares are down by 52.23%, underperforming the S&P 500, but don't assume that it can now be tagged as cheap and attractive. Based on its current price in relation to its earnings, MGG is still more expensive than most of the other companies in its industry.

We've downgraded

TJX

(TJX) - Get Report

, which operates as an off-price retailer of apparel and home fashions, from buy to hold. Strengths include its revenue growth, growth in earnings per share and largely solid financial position with reasonable debt levels by most measures. However, as a counter to these strengths, we also find weaknesses including weak operating cash flow and poor profit margins.

Revenue increased slightly by 2.2% since the same quarter a year ago, improving EPS by 7.4% in the most recent quarter. The company has demonstrated a pattern of positive earnings per share growth over the past two years, which we feel should continue, suggesting improving business performance. During the past fiscal year, TJX increased its bottom line by earning $1.68 vs. $1.62 in the prior year. This year, the market expects an improvement in earnings $2.07. The current debt-to-equity ratio, 0.41, is low and is below the industry average, implying successful management of debt levels. The quick ratio of 0.17, however, is very weak and demonstrates a lack of ability to pay short-term obligations.

TJX's gross profit margin of 28% is lower than desirable, but it has managed to increase from the same period last year. Its net profit margin of 5% compares favorably with the industry average. Net operating cash flow has decreased to $258.42 million, or 26.94% when compared with the same quarter last year, but TJX is still fairing well by exceeding its industry average cash flow growth rate of -49.77%.

We've downgraded

Tupperware Brands

(TUP) - Get Report

, which operates as a direct seller of various products across a range of brands and categories through an independent sales force, from buy to hold. Strengths include its revenue growth, notable return on equity and impressive record of earnings per share growth. However, as a counter to these strengths, we also find weaknesses including generally poor debt management and a generally disappointing performance in the stock itself.

Revenue rose by 12.8% since the same quarter a year ago, outperforming the industry average of 5.4% and boosting EPS. Tupperware reported significant earnings per share improvement in the most recent quarter compared to the same quarter a year ago. The company has demonstrated a pattern of positive earnings per share growth over the past two year, which we feel should continue. During the past fiscal year, the company increased its bottom line by earning $1.87 vs. $1.54 in the prior year. This year, the market expects an improvement in earnings to $2.60 versus $1.87. Tupperware's gross profit margin is rather high at 66.8%, but it has managed to decrease from the same period last year.Net profit margin of 5.4% compares favorably with the industry average. The debt-to-equity ratio of 1.23 is relatively high when compared with the industry average, suggesting a need for better debt level management. Along Tupperware also maintains a quick ratio of 0.70, which illustrates the inability to avoid short-term cash problems.

Shares are down by 51.7% on the year, underperforming the S&P 500. Naturally, the overall market trend is bound to be a significant factor, and in one sense, the stock's sharp decline last year is a positive for future investors, making it cheaper (in proportion to its earnings over the past year) than most other stocks in its industry. But due to other concerns, we feel the stock is still not a good buy right now.

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.
