Thursday turns out a bad day for investors as major indices slipped by more than 1% amid pressure from declining global markets and hours before Fed Chair Janet Yellen speech on inflation scheduled after the bell. However, in the crowd of many declining stocks, including Caterpillar Inc. , which slipped by over 7% , several stocks are registering large upside, although many of them are small- and nano-cap companies that don't have a large impact on the overall market.
