Jim Cramer's Portfolios of the Week

Updated from 6:59 a.m. EDT

Jim Cramer isn't letting record high crude oil prices dampen his outlook on the markets. In fact, Cramer believes investors should use the strength in commodities to make money. Recently, Cramer found opportunity in wind-related stocks, stock plays he's screwed up in the past and gold stocks.

Here are some Cramer highlights from over the past week as aggregated from his "Mad Money" TV show, the "Stop Trading!" segment on CNBC and his RealMoney blog posts (these blog post links require a RealMoney subscription).

Cramer's Favorite Natural Gas Stocks: Recently, Cramer said 2008 is "the year of natural gas." On Tuesday's "Mad Money" show, Cramer told viewers: "With the growth rates for a natural gas drillers averaging 15%, investors will be hard pressed to find such high growth in any other sector." Cramer's Favorite Natural Gas Stocks include El Paso EP and EnCana ECA among others.

Cramer's Wind Stock Picks: Comments by Warren Buffett on Wednesday's CNBC "Squawk Box" segment helped Cramer realize that wind mills are in short supply. In a May 7 blog post, he wrote: "We caught a moment earlier this week when it became clear to me that wind power may be the biggest sleeper out there." Cramer's Wind Stock Picks include names like Broadwind Energy BWEN among others.

Cramer's Gold-Is-Back Stock Picks: Cramer believes investors should once again look toward gold to make money. On Thursday's "Stop Trading!" segment, Cramer told viewers: "Oil is correlated to supply and demand. The stocks are signaling that gold is going higher." Cramer's Gold-Is-Back Stock Picks include Yamana Gold AUY among others.

Cramer's Mea Culpa Stocks: All week long, Cramer has been talking about some of his blown calls in hopes that viewers can learn from his errors. On Wednesday's "Mad Money" show, Cramer told viewers: "My real mistake was greed. Despite recommending Schering-Plough SGP at $16, I did not take a profit when the stock hit $31." Cramer's Mea Culpa Stocks include Google GOOG among others.
