Many investors track the largest increase in short selling, but there is another crucial way to look at short interest: the days to cover often tells just how actively shorted a stock is, as does a large percentage of its float. More importantly, these often represent a longer-term bias by the trading community. We have tracked the NASDAQ and NYSE short interest data today to screen for companies with the highest days to cover ratios (all are over one months of trading volume). We also looked for a high percentage of its shares outstanding or its float to be in the short interest. Almost all of these also had an increase in the period from August 31 to September 15 settlement dates.
