$NIO has not shown much improvement, with the short-term moving averages continuing to weaken and remaining below the 200-day moving average. Speaking of which, there are indeed good opportunities like $GDS emerging in the Chinese market now, but the problem is—you need a simple and effective screening criterion. The most basic rule is this simple: only trade those assets whose short-term moving averages are still trending upward and are above the 200-day moving average. Mastering this can help you avoid many detours.
