老师好，百题投资第7题，看了解析，还是似懂非懂。 Value and momentum are opposite each other in that value investing is inherently stabilizing. It is a negative feedback strategy where stocks that have fallen in value eventually are priced low enough to become value investments, pushing prices back up. Momentum is inherently destabilizing. It is a positive feedback strategy where stocks that have been increasing in value are attractive to investors, so investors buy them, and prices increase even more. Momentum can be riskier than value or size investing in that it is more prone to crashes. 价值策略是负反馈，追涨杀跌是正反馈是什么意思呢？价值策略不是HML吗？不是买入价值高的卖出价值低的么？怎么说是股票价格足够低成为价值投资呢？请老师帮助理解一下这部分内容，谢谢
