This past week, Jim Cramer's "Mad Money" took it back to the college campus with a visit to Indiana University. In his live show there on Wednesday and throughout the week he had plenty of suggestions on how to play the current markets. Here are some the highlights from Jim over the last week (aggregated from Mad Money, Stop Trading!, and his articles):

Cramer’s Iran Awry Portfolio : This past week, Jim thought it was important to focus on the best investment ideas to protect ourselves given the recent geopolitical tensions with Iran. So Cramer presented his Cramer’s Iran Awry Portfolio on Monday's "Mad Money" TV show. His recommendations consisted of a mix of defense, oil, gold and cash plays including ABT.
