After the turn of the calendar page, quarterly reporting resumes this week. Analysts surveyed by Thomson Reuters are expecting to see strong earnings growth from fertilizer producer Mosaic Co. (NYSE: MOS), biotech giant Monsanto Co. (NYSE: MON), and Neogen Corp. (NASDAQ: NEOG), which produces food safety and animal health products. Mosaic's estimated earnings per share of $1.43 for the fiscal second quarter would be 41.9% higher than a year ago, and its revenue estimate of $3.0 billion is 36.7% higher. Monsanto's $0.59 per share projection for the fiscal first quarter is 22.0% higher and sales of $2.4 billion are up 14.9%. And Neogen's second-quarter $0.25 per share would be 12.0% higher, while its sales of $32.3 million are up 18.6%. All three have tended to beat expectations in recent quarters, and all three have buy recommendations from a consensus of analysts. Mosaic and Monsanto have recently announced dividends, and their share prices have fallen 62.3% and 39.0%, respectively, from a year ago. The share price of Neogen, which recently announced share buybacks, is only 0.8% lower.

Other companies expected to post modest earnings gains when they report this week include education company Apollo Group Inc. (NASDAQ: APOL), WD-40 Co. (NASDAQ: WDFC), and wine and spirits maker Constellation Brands Inc. (NYSE: STZ).

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.

On today's STOP TRADING segment on CNBC, Jim Cramer was on the road on a back-to-school special and he was dismissing the "drop" today as almost nothing. On RPM International Inc. (NYSE:RPM), Cramer said it is going to $30.00 and he likes it (he interviewed the CEO recently too).

On The Middleby Corporation (NASDAQ:MIDD), Cramer thinks it is very consistent and it delivers. Intevac, Inc. (NASDAQ:IVAC) is another one Cramer likes.

On IAC/InterActiveCorp (NASDAQ:IACI) Cramer said the quarter wasn't bad like the street thought. The buy side is right the sell side is wrong and he thinks IACI is going to mid-$40's. We noted last month that Barry Diller was one of the top entrenched CEO's.
