Buy the dip? Not necessary. I always buy quality company, those with lots of cash and ROE more than 20%. Also, not everyone has huge cash to buy the dip - so those without a lot of cash to buy more, at least don’t panic sell when market is bad. Again, good company always re-bounce. Hang in there fellow investors!
