I wonder why

I wonder why we can't ride the rising waves

Yesterday's impressive sales news. From a 5% rise, it fell less than a day later... I don't like Zanmo. It's the usual pattern.

Even though materials were available, arms that rose to the same level yesterday are rising today too...

I wonder why it doesn't rise only on stocks that are held, and only on stocks that are non-holed or have only a small amount of money put in
