Morning Edge is published for research and education only. It is not investment, financial, legal or tax advice, and nothing in it is a recommendation or offer to buy or sell any security. It is general information written for every reader alike and does not consider your goals, finances or risk tolerance. Model readings such as the asymmetry ratio are untested. Our own backtest found the ratio predicts how big a move may be, not which way it goes. Data can be late or wrong. Past results do not predict future results, and you can lose money investing. The authors may hold positions in securities mentioned. Do your own research and talk to a licensed financial adviser before you invest.
