Clorox

(CLX) - Get Report

to "buy."

The numbers

: Fiscal fourth-quarter revenue increased marginally to $1.5 billion, but net income ascended 8% to $170 million and earnings per share climbed 6% to $1.20, restrained by a higher count. The operating margin rose from 19% to 21% and the net margin inched past 11%. Clorox has a weak liquidity position, evident in its quick ratio of 0.4. And $3.1 billion of debt indicates sizable leverage.

The stock

: Clorox is up 3% in 2009, underperforming major U.S. indices. The stock trades at a fair price-to-earnings ratio of 15 and offers a 3.5% dividend yield.

The model upgraded

Canadian Imperial Bank of Commerce

(CM) - Get Report

to "hold."

The numbers

: Fiscal second-quarter revenue rose 29% to $3.1 billion, but the company swung to a net loss of $51 million, or 24 cents a share, from a loss of $1.1 billion, or $3 a share, a year earlier. The operating margin climbed from negative territory to 6% and the net margin remained in shallow negative territory. The company has adequate liquidity, reflected by $8.3 billion of cash. But $59 billion of debt indicates excessive leverage.

The stock

: Canadian Imperial has advanced 45% in 2009, more than major U.S. indices. The stock trades at an expensive price-to-earnings ratio of 53, but offers a 5.3% dividend yield, higher than the average of S&P 500 companies.

The model upgraded conglomerate

General Electric

(GE) - Get Report

to "hold."

The numbers

: Second-quarter net income dropped 47% to $2.7 billion and earnings per share fell 52% to 26 cents, hurt by a higher share count, as revenue declined 16% to $39 billion. The operating margin decreased from 28% to 20% and the net margin descended from 11% to 7%. GE holds $52 billion of cash reserves, but a debt-to-equity ratio of 4.6 and $4.6 billion of quarterly interest expenses indicate excessive leverage.

The stock

: General Electric is down 16% in 2009, underperforming major U.S. indices. The stock trades at a cheap price-to-earnings ratio of 10 and offers a 3% dividend yield.

The model upgraded alcohol producer

Constellation Brands

(STZ) - Get Report

to "hold."

The numbers

: Fiscal first-quarter earnings plummeted 85% to $6.5 million, or 3 cents a share, as revenue dropped 15% to $792 million. The operating margin rose from 14% to 15% and the net margin dipped below 1%. A quick ratio of 0.5 and just $17 million of cash indicate an inadequate liquidity position. And a debt-to-equity ratio of 1.9 demonstrates excessive leverage. We give Constellation Brands a financial strength score of 4.9 out of 10, less than the "buy"-list average of 7.

The stock

: Constellation Brands has dropped 10% in 2009, underperforming major U.S. indices. The company doesn't pay dividends.

The model upgraded publisher and news provider

Thomson-Reuters

(TRI) - Get Report

to "buy."

The numbers

: Second-quarter net income surged 82% to $315 million and earnings per share climbed 73% to 38 cents a share, restrained by a higher share count, as revenue increased 5% to $3.3 billion. The operating margin rose from 16% to 18% and the net margin jumped from 6% to 10%. A quick ratio of 0.8 indicates less-than-ideal liquidity. But a debt-to-equity ratio of 0.4 demonstrates conservative leverage.

The stock

: Thomson-Reuters has ascended 10% in 2009, beating the

Dow Jones Industrial Average

and

S&P 500 Index

. The stock trades at a fair price-to-earnings ratio of 17 and offers a 3.5% dividend yield.
