Cramer's 'Mad Money' Recap: Bling's the Thing

Water consumption in the 20th century has grown at twice the rate of population growth, Cramer said, and over the next 20 years, even the most conservative estimates expect hundreds of billions of dollars will be spent on water infrastructure. Cramer owns Aqua America (WTR Quote - Cramer on WTR - Stock Picks), which operates public water utilities in a number of cities, but Aqua America "doesn't expose you to the massive nature of our water shortage," he said.

A "brilliant way to play the water shortage" is through an ETF, PowerShares Water Resources (PHO Quote - Cramer on PHO - Stock Picks) Cramer said. PHO, which just launched this week, is composed of 64% small-cap stocks, but also contains large companies such as Suez (SZE Quote - Cramer on SZE - Stock Picks) and Veolia Environnement (VE Quote - Cramer on VE - Stock Picks).

Don't pay up for PHO, though, said Cramer. An ETF is simply a basket of stocks trading as one stock. (Check out this Street.com article for more information on this ETF.)

In response to a question about an international water play, Cramer said Suez would be the way to play it.

Cramer also said that Walter Industries' (WLT Quote - Cramer on WLT - Stock Picks) plan to spin off its water business is a great idea.

Pick of the Week

Cramer's "Pick of the Week" is Salesforce.com (CRM Quote - Cramer on CRM - Stock Picks). The company makes customer relationship management software that competes with Microsoft (MSFT Quote - Cramer on MSFT - Stock Picks), SAP (SAP Quote - Cramer on SAP - Stock Picks) and Oracle (ORCL Quote - Cramer on ORCL - Stock Picks). Salesforce.com's advantage is it can deliver its software entirely over the Web, Cramer said.

CRM software was a $3.5 billion market in 2004, and Salesforce.com has just 3.2% market share. But the market for Web-based, on-demand CRM software is growing faster than the traditional market, which means Salesforce.com can't help but to pick up market share, Cramer said.

The stock isn't cheap, he noted, but it's worth a premium for its growth and for the fact the company has never missed earnings. An added bonus is the fact the stock doesn't get the coverage it deserves on Wall Street, he said. So, "get in now before it becomes the darling of every growth fund in town."
