LONDON -- I'm always searching for shares that can help ordinary investors like you make money from the stock market.

So right now I am trawling through the FTSE 100 (UKX) and giving my verdict on every member of the blue-chip index. Simply put, I'm hoping to pinpoint the very best buying opportunities in today's uncertain market.

Today I am looking at BHP Billiton (LSE: BLT.L) (NYSE: BBL) to determine whether you should consider buying the shares at 1,950 pence.

I am assessing each company on several ratios:

  • Price/Earnings (P/E): Does the share look like a good value when compared against its competitors?
  • Price Earnings Growth (PEG): Does the share look like a good value factoring in predicted growth?
  • Yield: Does the share provide a solid income for investors?
  • Dividend Cover: Is the dividend sustainable?

So let's look at the numbers:

Stock

Price

3-year EPS growth

Projected P/E

PEG

Yield

3-year dividend growth

Dividend cover

BHP Billiton 1,950p 36% 11.5 N/A 3.6% 29% 2.9

The consensus analyst estimate for next year's earnings per share is $2.69 (20 % fall) and dividend per share is $1.23 (3% growth).

Trading on a projected P/E of 11.5, BHP appears to be more expensive than its peers in the mining sector, who are currently trading on an average P/E of 5.7. Indeed, BHP's P/E ratio and negative growth rate gives a PEG ratio of less than zero. With a negative result, the PEG ratio cannot help with my analysis.

Supporting a 3.6% yield, the dividend is above average for the mining sector, which currently offers a 2.9% average yield. BHP also has a three-year compounded dividend growth rate of 29%. However, the growth rate is coming under pressure this year from lower commodity prices.

Nonetheless, the dividend is nearly three times covered. What's more, BHP has returned almost $54 billion to shareholders through dividends and buybacks over the last 10 years, and returned $15 billion during 2011 alone!

BHP appears expensive, with slowing growth
BHP looks to be expensive compared to its peers. However, as the world's biggest diversified miner, I believe the company does deserve a premium. Indeed, unlike most miners, BHP has not cut its dividend in 100 years!

BHP's management is focused on a strategy of improving margins and diversifying into a resources company, rather than operating as a pure miner. I believe this strategy is already starting to benefit shareholders. You see, during 2012, BHP's earnings fell by $1.5 billion due to lower base-metal prices; however, BHP's record petroleum output provided a commensurate $1.5 billion boost to profits.

Due to intensive capital spending, BHP saw its level of debt rise by 150% during 2012. With fears of rising debt, the management of the company has scaled back the pace of spending -- with some major projects being put on hold. Management is also selling non-core projects.

In my opinion, BHP looks to be good value. The diversification into a wider resources company has reduced the pressure of falling metals prices while margin improvements are maintaining shareholder returns.

Even though growth is slowing, I believe now looks to be a good time to buy BHP Billiton at 1,950 pence.

More FTSE opportunities
As well as BHP Billiton, I am also positive on the FTSE shares highlighted in "8 Dividend Plays Held By Britain's Super Investor."
