I am the Global Editor at MoneyShow.com and each week I interview an investing expert. This week, I spoke with Vahan Janjigian, editor of Forbes Growth Investor, who discusses how the economic crisis affects his strategy and mentions some good international growth stocks.

Q. Vahan, although you primarily recommend US equities, your newsletter also includes a few international picks, such as American Oriental Bioengineering (NYSE: AOB) and Embraer (NYSE: ERJ). What factors made you choose these companies?

A. I do recommend foreign companies from time to time in the Forbes Growth Investor, but only if they trade on US exchanges and only if they show up at the top of my screens. I rely on a quantitative model that screens stocks based on the probability of out-performance over the next six to 18 months. I like AOB because it sells traditional Chinese plant-based pharmaceuticals in China. Demand is very strong for these natural products in that country. I like ERJ because it gives us exposure to Brazil, which has one the fastest growing economies in Latin America.

Q. Several of your recommendations are US-based multinationals, such as RPM (NYSE: RPM) and Amdocs (NYSE: DOX), both of whom do significant business around the world. How important was their international exposure to your selection, and why?

A: International exposure is not something I normally focus on. Besides, these days most mid- to large-sized companies have at least some international exposure. Because the global economic outlook is so uncertain at this time, I felt more comfortable with companies that have a diversified revenue stream.

I had no idea when I posted yesterday about two Israeli stocks to buy for a market bounce that one of the stocks I mentioned would spike more than 10%. Amdocs Limited (NYSE: DOX) is the market leader in customer experience systems innovation, enabling world-leading service providers to deliver an integrated, innovative and intentional customer experience at every point of service.

The company has experienced one heck of a 48 hours. On Tuesday there was the news that Sprint/Nextel Corporation (NYSE: S) is soft-launching a WiMAX network, and picked communications software company Amdocs to build and maintain the Xohm web portal and manage its customer service, billing, and other operations.

Even bigger is the news today that Amdocs signed a deal to provide support services to AT&T (NYSE: T), which one analyst estimated is worth more than $100 million a year. Wedbush Morgan analyst Scott P. Sutherland reiterated a "Strong Buy" rating on Amdocs, and estimated that the deal "is initially worth well over $100 million annually and has the potential to be even more."

Like other big businesses, most telecommunications firms find it cost effective to farm out development of their customer interface software systems. One of the best known developers of the specialty programs is headquartered in Chesterfield, Missouri.

Amdocs Limited (NYSE: DOX) provides customer relationship management, sales, and billing software used by telecommunications service providers. It also sells publishing software for generating print and online directories and offers a variety of outsourced communications facility management services. Clients include AT&T (NYSE: T), Alltel (NYSE: AT), Comcast (NASDAQ: CMCSA), Nortel Networks (NYSE: NT), Qwest Communications International (NYSE: Q), Sprint Nextel (NYSE: S) and Verizon Communications (NYSE: VZ).

The stock popped on Monday, powering through 50-day and 200-day moving average resistance levels, on rumors of the potential for a bid from private equity. There was clearly interest in June $40 calls that day, implying more than just idle chatter.

Heading to Memorial Day, there's certainly no moratorium on the number of talked about potential deals. Receiving a fair amount of attention over the last few days include the companies below. There's more, of course, but hey, it's a three-day weekend.

LAM RESEARCH CORPORATION (NASDAQ: LRCX)

This supplier of tools that makes microchips keeps seeing its stock move up. Up about 13% over the last few months. And it may be more than speculation that it will soon be acquired. Investors looking for a deal are snapping up equity calls, some are then selling them, and keeping both eyes on the stock price. Others are looking out to see which private equity firms or "strategic" buyers come calling.

AMDOCS LIMITED (NYSE: DOX)

As Alltel Corporation (NYSE: AT) goes, so goes Amdocs? Well, not quite. Yes the Alltel sale has pushed Amdocs' stock upward. Some say this maker of software products for telecom services firms may want to continue to go forward by themselves. But that hasn't stopped that list of potential buyers from being passed around. Best bet: International Business Machines Corporation (NYSE: IBM).

CIRCUIT CITY STORES (NYSE: CC)

Again, here we go: Is it going to take a buyout? (Read: private equity buyer.) Or a miracle? (Read: new management) There are profit warnings. (Read: red flags everywhere) The stock is in miserable shape. (Read: cheap) Tough competition. (Read: Wal-Mart Stores Inc (NYSE: WMT)). Think there's a book to be written about all of this? (Read: who'd want to?).

APPLEBEE'S INTERNATIONAL INC (NASDAQ: APPB)

Food for thought. Kangaroo Holdings wants to buy OSI Restaurant Partners Inc (NYSE: OSI). Not surprisingly, Applebee's stock goes up. Are they cooking up a sale price for themselves as they "evaluate" offers? You betcha.

PALM INC (NASDAQ: PALM)

Going, going...almost gone. Even we're beginning to tire of this one. But it never gets old if you like to watch. Now, they're canceling conferences. The CEO is selling shares. The CFO has a bad back. Come on! The latest product review - Palm Treo 755p - is terrible. Market share is going down the tubes. R&D? Forgetaboutit. Sound like a company on the go? Right. Right into someone else's lap. And to think what they once were. Great job all around, everybody.

On today's STOP TRADING! segment on CNBC, Jim Cramer has been looking for numbers to go up on the weak dollar, but the very recent strength will keep that from happening. Cramer thought that would happen for Altria Group, Inc. (NYSE:MO), Caterpillar Inc. (NYSE:CAT), and Pfizer Inc. (NYSE:PFE), so now he isn't looking for bump ups in forward numbers. He still likes MO, but he's now not looking for an extra earnings bump since the dollar isn't continuing to slide.

Amdocs Limited (NYSE:DOX) was noted with a little concern by Cramer, although he still wants to give it the benefit of the doubt. The stock is down by more than 9%.
