Recent short sell / trading data (from SGInvestors)

• 
  
  On 15, 16, 17, and 19 September, the short sell volumes were very elevated relative to total trading volume &mdash especially 15, 19, and 22 Sept, where the short volumes comprise ~25&ndash 33 % of the trading volume.
• 
  
  On 17 Sept, the short ratio falls to ~11.8 %, which is still high.
• 
  
  The days in between (like 18, 20, 21) either have missing short volume data in the publicly aggregated chart or are not listed explicitly in that source.

🔍 What this suggests

• 
  
  Short sell volumes of ~25-33 % of total volume are unusual and significant. For most stocks, that level of daily shorting (one quarter to one third of trades) would reflect very aggressive bearish bets or even a kind of targeted attack.
• 
  
  That level (especially if persistent over days) strains typical definitions of &ldquo normal background shorting.&rdquo
• 
  
  Because the short volumes are so large relative to total trading volume, it suggests considerable pressure from short sellers.
