Sector rotation has been proven to make good profits at the least risk if it is properly implemented. This book improves your odds in making profits than traditional schemes in sector rotation by: -Market Timing. When the market is plunging, do not buy any stock including sector ETFs and sector funds. This book provides a simple chart to detect market plunges.
