Good day on the market

Today, the stock market went up by 18+ points. That means under 0.5% rise. Why do I call it a good day? One portfolio went up by 1.98% and the other went up by 1.2%.

POG went up so my numerous gold stocks obliged. Why investors function day to day, I have no explanation.

But note: ABU had a good annoucement, extending its surface gold by 102m. And the share price at close didn't move at 5.6c.

What are investors doing?
