BOSTON ( TheStreet) -- TheStreet.com's stock-rating model upgraded Avery Dennison ( AVY), a maker of office supplies, pressure-sensitive materials and labels, to "hold."

The numbers: Second-quarter net income dropped 57% to $40 million and earnings per share fell 59% to 38 cents, hurt by a higher share count. Revenue decreased 20% to $1.5 billion. Its gross margin remained steady at 30%, but its operating margin fell from 8% to 6%. A quick ratio of 0.5 indicates less-than-ideal liquidity. A debt-to-equity ratio of 1.6 indicates excessive leverage.

The stock: Avery Dennison is up 6% this year, trailing major U.S. indices. The company suffered from a $9 a share net loss in the first-quarter and halved its quarterly dividend. Shares pay a 2.3% dividend yield.

The model upgraded Coeur d'Alene Mines ( CDE) to "hold."

The numbers: The company swung to a second-quarter profit of $12 million, or 17 cents a share, from a loss of $5.4 million, or 10 cents a share, in the year-earlier period. Revenue increased 46% to $73 million. Its gross margin dropped from 50% to 31% and its operating margin remained in negative territory. A quick ratio of 0.5 indicates less-than-ideal liquidity. But a debt-to-equity ratio of 0.1 demonstrates modest leverage.

The stock: Coeur d'Alene Mines has surged 138% this year, outpacing major U.S. indices. The stock trades at a price-to-earnings ratio of 76, a premium to the market and precious metals peers. The company does not pay dividends.

The model upgraded Covidien ( COV), maker of health care products and devices, to "buy."

The numbers: Fiscal third-quarter net income jumped 5% to $281 million, but earnings per share fell 17% to 54 cents. Revenue dropped 3% to $2.5 billion. Its gross margin rose from 58% to 59%, but its operating margin fell from 22% to 20%. A quick ratio of 1.4 indicates ample liquidity. A debt-to-equity ratio of 0.4 reflects conservative leverage.

The stock: Covidien is up 15% this year, beating the Dow Jones Industrial Average, but underperforming the S&P 500 Index. The stock trades at a price-to-earnings ratio of 17, a discount to the market and health care equipment peers. Shares pay a 1.5% dividend yield.

The numbers: The company swung to a second-quarter loss of $8 million, or 6 cents a share, from a profit of $86 million, or 62 cents a share, in the year-earlier period. Its gross margin declined from 21% to 16% and its operating margin fell from 13% to 9%. A quick ratio of 0.5 indicates weak liquidity. But a debt-to-equity ratio of 0.5 demonstrates conservative leverage.

The stock: Spirit AeroSystems has ascended 68% this year, beating major U.S. indices. The stock trades at a price-to-earnings ratio of 16, a discount to the market, but a premium to aerospace and defense peers. The company does not pay dividends.
