Never ever sell stock at key support : stock investment 101

Many people are so scared of yesterday. But as I said, unless and until that support is broken, you have to hold strong. Dont let emotion overtaking you.

If you think mathematically, selling at QQQ 469 vs selling at QQQ 462 (if support is truly broken) makes zero difference in the long term of your porfolio, only less than 1.5% difference.

This is why standing strong in the face of key support test will help you in the long term.
