I read an article in the 'most popular' section a few years ago about a new share trading paradigm. The author was talking about predicting share high points and when to pull in and out of the market. He was saying the old adage of buy and hold wouldn't stand up in the modern environment, and investors would need to be more active in the market. I think 'risk on, risk off' was also discussed. I know this a bit vague, but does it ring a bell with anyone?
