The Foolish bottom line
If you're an investor in one of these stocks, you need to read the quarterly reports to see how the company is performing and check in on what management thinks about the current industry climate. Furthermore, if you're a serious investor, try to read the conference-call transcripts to get an even better idea of whether your stocks are good to hold, or whether you might want to toss them in the trash.
