BOSTON ( TheStreet) -- Disney ( DIS), Molson Coors ( TAP), NYSE Euronext ( NYX) and FPL Group ( FPL) had their ratings changed by TheStreet.com. (Yesterday, SunPower ( SPWR) and other companies had their ratings changed.)

1. The model downgraded entertainment company Disney, which reported quarterly results Tuesday, to "hold."

The numbers: Fiscal first-quarter net income declined marginally to $844 million, but earnings per share dropped 2.2% to 44 cents, hurt by a larger float. Excluding one-time charges, profit improved, helped by the company's Media Networks segment. Disney's operating margin widened from 13% to 15%. The company holds $3.2 billion of cash and $14 billion of debt. The model awards Disney a financial strength score of 8.9 due to consistent profitability.

The stock: Disney increased 59% during the past year, beating major U.S. indices. The stock is down 7.3% over a two-year span. The shares are undervalued relative to those of media peers based on trailing earnings, projected earnings, book value and sales. A PEG ratio of 1.9 indicates that Disney is expensive when considering growth expectations. Disney garners a growth score of 3.2 and a volatility score of 3.3.

2. The model downgraded brewer Molson Coors, which released quarterly figures Tuesday, to "hold."

The numbers: Fourth-quarter profit more than doubled to $222 million, or $1.17 a share, as revenue climbed 11% to $821 million. The company's operating margin declined from 13% to 12%. A quick ratio of 0.9 and debt-to-equity ratio of 0.2 demonstrate financial stability. The model awards Molson Coors a financial-strength score of 7.9 out of 10.

The stock: Molson Coors increased 6.7% during the past year, underperforming major U.S. indices. The shares are cheap relative to those of beverage peers based on all of our valuation measures, including trailing earnings, projected earnings, book value, sales and cash flow. The model awards Molson Coors a performance score of just 4.5.

3. The model upgraded exchange operator NYSE Euronext, which released quarterly results Tuesday, to "hold."

The numbers: NYSE Euronext swung to a fourth-quarter profit of $172 million, or 66 cents a share, from a loss of $1.3 billion, or $5.07, a year earlier. Revenue decreased 6.9% to $1.1 billion. NYSE Euronext's operating margin ascended from 18% to 19%. A quick ratio of 0.5 indicates weak liquidity. However, the company's 0.4 debt-to-equity ratio is less than the industry average, reflecting conservative leverage.

The stock: NYSE Euronext advanced 16% during the past year, trailing major U.S. indices. The shares are cheap relative to those of financial-services peers based on projected earnings and sales. They are costly when considering trailing earnings and book value. NYSE Euronext has a PEG ratio, a measure of value relative to growth, of 0.2, implying that its shares are undervalued. The industry average is 0.7.

4. The model downgraded electric utility FPL Group to "hold."

The numbers: Fourth-quarter profit dropped 15% to $348 million, or 85 cents a share, as revenue decreased 8.6% to $3.7 billion. FPL's operating margin narrowed from 19% to 15%. FPL holds $238 million of cash and $19 billion of debt. Its 1.5 debt-to-equity ratio is higher than the industry average, indicating excessive leverage. FPL's 0.4 quick ratio demonstrates weak liquidity.

The stock: FPL fell 9% during the past year, trailing major U.S. indices. The shares are cheap relative to those of electric utility peers based on all of our valuation measures, including trailing earnings, projected earnings, book value, sales and cash flow. The stock's PEG ratio of 1.2 indicates that FPL is expensive relative to growth expectations. Still, that figure is well-below the industry average of 4.
