I actually didn't plan to increase my position in these U.S. mining stocks, but FCX has risen again, driven by copper prices, right? Analysts say it's good, but can it really rise like this? The key is that the accounting officer actually reduced his position. Wow, does he know something... Law firms are filing class actions one moment and reminding deadlines the next. I sit in front of the screen every day, anxious about this. Alcoa is even more outrageous—it hit a new high despite being downgraded. Others say it's risen too much and to be careful, but I just can't resist. I just don't believe it. A 93% gain in six months—did I miscalculate, or is this market really holding up? CDE surged too much recently and dropped today. Some directly said the valuation can't hold. What's the progress with Newmont's acquisition? Options trading is still quite active. Feels like something fishy is about to happen.
