For the past half month, my A-share portfolio has also been full of tech stocks, plus US stocks have been plummeting every day, so I've had no mood to research the daily hot spots. Yesterday, US stocks stopped falling, and A-shares and Korean stocks opened in the green (lj Samsung opened red), which got me energized, and I was too lazy to use the sleep strategy again. I used a friend's strategy from the last few months, and today there was a big surge, with a full position gain of seven points. The specifics are: kill all the green ones every day, buy the best-performing stock of the day, or evenly spread across the strongest sector of the day.
