The Foolish bottom line
If you're an investor in one these stocks, it's important to read the quarterly reports to see how the company is performing and to see 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 they should possibly be tossed in the trash.
