Jim Cramer's Portfolios of the Week

Updated from 10:30 a.m. EDT

Jim Cramer isn't afraid to tell investors when a sector is in trouble and it's time to get out.

A group of stocks could be under attack from the short-sellers, momentum funds or even the technical traders. No matter what the reason, Cramer will sound the alarm and warn his viewers to avoid the targeted group. He also isn't afraid to tell his fans that the selling might be unjustified and investors should use the dips as buying opportunities.

Cramer knows what it takes to make money in the market, and his TV shows and online columns are all about passing that knowledge along to ambitious investors. Don't miss what Cramer has to say. It could cost you an opportunity.

Recently, Cramer found opportunity in tech stocks, such as Research In Motion(RIMM Quote - Cramer on RIMM - Stock Picks); war hawk stocks, such as Halliburton(HAL Quote - Cramer on HAL - Stock Picks); and three stocks he feels the market has unfairly beaten-up, including Fluor(FLR Quote - Cramer on FLR - Stock Picks). Here are some Cramer highlights from over the past week as aggregated from his RealMoney blog posts (these blog post links require a RealMoney subscription).
