NEW YORK (TheStreet) -- Let's put it this way, I'm one of those analysts who "eats his own cooking." Put another way, I "put my money where my mouth is." On the other hand, I like to remind readers to do their own thorough due diligence before investing a dime.

Let me also remind you that I'm the same person who proclaimed the death of gold and silver stocks in an ironic and perhaps desperate attempt to jump-start this comatose sector. So don't automatically do as I do, for I'm often early to the sector "resurrections."

Now that I've said all that, I've also seen "bottoming" formations where the stock of a cash-generating sector leader gets so oversold that I want to start accumulating shares and collecting dividends. That's the way I'm starting to see BHP Billiton ( BHP).

BHP is a leading global resource company, and I like the way the company describes itself at its user-friendly website: "We are among the world's largest producers of major commodities, including aluminum, copper, energy coal, iron ore, manganese, metallurgical coal, nickel, silver gold and uranium along with substantial interests in oil and gas."

Please read that again and ask yourself where you're going to get all those valuable, essential commodities by buying the shares of just one company. The company continues: "We are a global organization headquartered in Australia and with over 100 locations throughout the world, our success is underpinned by the 100,000 employees and contractors that work at BHP Billiton."

Have I mentioned that's how they can pay a 3.26% dividend, which represents a payout ratio of only 38%? With well over $5.2 billion in total cash as of the end of 2012 and trailing 12-month operating cash flow of more than $18.5 billion, it is reasonable to expect future rising dividend payouts.

"We have an unrivaled portfolio of high-quality growth opportunities that will ensure we continue to meet the changing needs of our customers and the resources demand of emerging economies at every stage of their growth," BHP's leadership proclaims. The company also boasts some impressive company credibility.

"We have a proven record of delivering superior shareholder returns. We do this through the disciplined execution of our unchanged strategy of owning and operating large, long-life, low-cost, expandable, upstream assets diversified by commodity, geography and market."

Now's a good time to look at a five-year chart of BHP shares with the focus on price and year-over-year retained quarterly earnings, which as of the end of 2012 was higher than 17%. BHP Chart BHP data by YCharts

While the S&P 500 and the Dow Jones Industrial Average keep knocking the ball out of the park day-after-day, so does the MSCI Australia Index of Stocks as represented by the iShares Australia ETF ( EWA) with the same name. Take a look at its five-year chart below. It's time for BHP to catch up as there appears to be a "disconnect" that few are taking notice of. EWA Chart EWA data by YCharts

Here's the big news about BHP's share price. On April 10, Matt Badiali, the editor of The S&A Resource Report, pointed out in The Growth Stock Wire that BHP's stock is down 30% from its 2011 peak and that its price-to-book value is quite attractive.

Badiali wrote: "Take a look at the chart below. It tracks the last 13 years of BHP's price-to-book ratio. Book value is simple. It's essentially the value of all its mines. And right now, BHP is trading at an extreme low compared to book value.

"BHP is trading at about 2.7 times book value. Its price-to-book ratio has fallen below that level five times in the past 13 years. If you bought BHP stock at those points, you made double-digit gains every time."

That is a noteworthy observation. I would add that another compelling reason to consider BHP is because of its self-professed corporate strategy. The best way to describe it is to let the company speak for itself.

"Our strategy is to own and operate large, long-life, low-cost, expandable, upstream assets diversified by commodity, geography and market. Our strategy has remained unchanged for over a decade and has enabled us to deliver superior margins throughout economic and commodity cycles for many years.

"Our diversified, low cost, tier one asset base enhances the resilience of our cash flow by reducing our exposure to any one commodity or currency and provides for more predictable and robust financial performance. It allows us to invest in and grow our business throughout economic cycles thereby delivering superior long-term value to our shareholders."

BHP is not in an uptrend yet, and it briefly broke below $70 on April 11. It may have farther to fall before moving higher. Many of the metals and minerals it mines and produces are in price-correction mode, and that may be one of the reasons to be cautious about owning the shares yet.

As Badiali points out: "The average bottom in the price-to-book value is 2.44. At today's book value, that works out to $62 per share, about 10% below its current price. The low in the price-to-book value over the last 13 years is 2.16. That would be 18% below its current price."

Yet if you're willing to average down, now may be an opportunistic point to begin doing a bit of "schnitzeling" as our own Jim Cramer likes to call it. For those of you who don't know what "schnitzeling" is, it is Cramer's way of buying a little at a time.

If shares drop much lower, you can buy in larger increments. In the meantime, you'll be getting paid to wait with a rewarding dividend and nice upside potential. With a forward (one-year) PE ratio of 15 and its impressive trailing 12-month operating margin of nearly 30%, BHP looks very promising.
