Updated from 6:12 a.m. EDTJim Cramer isn't afraid to tell people to sell or to warn investors about problematic stocks. Cramer is famous for saying, "I'm not about making friends, I'm about making you money." He held true to that mantra this week when he advised investors on the "four horsemen" of tech. 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. Cramer's Indestructible Stock Picks: On Wednesday's "Mad Money" Cramer offered up some indestructible stocks that could make money in almost any economic environment. Cramer's Indestructible Stock Picks including Intuitive Surgical ( ISRG) and Google ( GOOG). Cramer's Four Horsemen Take: On a "Wall Street Confidential" video Wednesday, Cramer said: "At this point, people who didn't get into Apple ( AAPL), Research In Motion ( RIMM) or Amazon ( AMZN) have missed these stories, but what people haven't missed is Google."

Cramer's Mineral Stock Plays: Cramer believes the selling in the mineral stocks is overdone and the group could be ready to bounce. In an Oct. 22 blog post he wrote, "It never stops. We get a couple of articles about how the worldwide economy might be slowing and then everybody sells every mineral stock. Every one of them!" Cramer's Mineral Stock Plays include Freeport-McMoRan ( FCX).
Cramer's Oil Stock Picks: Cramer sees opportunity in buying oil stocks on dips. In an Oct. 23 blog post he wrote, "I believe that the way to buy these stocks is simple: when they come down 5%-7% buy them with the expectation that oil prices will firm because of demand, but when they spring back to new highs or have nice increases from where you bought them, sell them." Cramer's Oil Stock Picks included names like Chevron ( CVX). Cramer's AG Stock Picks: Cramer continues to be bullish on the agriculture sector.

Cramer's AG Stock Picks include Bunge ( BG) and Deere ( DE). Cramer's Georgia Tech Student Picks : On last Thursday's "Mad Money" show, Cramer dissected stock picks from the Georgia Tech investment committee.
