Most Active lists stocks on US OTC markets that are rising on unusual volume: today's or yesterday's volume is at least five times the 50-day average, and the price is up more than 5% over the last two days. The busiest are shown first; the top 100 are listed. A sharp advance on a volume surge usually means news, earnings or institutional buying, and such moves often continue for several days. Check the chart for resistance before chasing the move. OTC stocks trade outside the major exchanges and are often thinly traded penny stocks; the list covers US OTC stocks with at least $100,000 in average daily trading value.
