ProShares UltraShort Nasdaq Biotechnology seeks daily investment results before fees and expenses that correspond to twice (200%) the inverse (opposite) of the daily performance of the NASDAQ Biotechnology Index.
ProShares Ultrashort Nasdaq Biotechnology trades on the NASDAQ stock market under the symbol BIS.
As of March 23, 2026, BIS stock price declined to $9.65 with 15,561 million shares trading.
BIS has a market cap of $2.71 million. This is considered a Sub-Micro Cap stock.
In the last 3 years, BIS traded as high as $26.51 and as low as $8.31.
BIS has underperformed the market in the last year with a return of -41.2%, while SPY returned +17.9%. This shows that you would have done better investing in the overall market (through SPY) over the last year than in BIS shares. However, BIS has outperformed the market in the last 3 month and 2 week periods, returning +3.1% and +5.6%, while SPY returned -3.4% and -2.3%, respectively. This indicates BIS has been having a stronger performance recently.
BIS support price is $9.50 and resistance is $10.03 (based on 1 day standard deviation move). This means that using the most recent 20 day stock volatility and applying a one standard deviation move around the stock's closing price, stastically there is a 67% probability that BIS shares will trade within this expected range on the day.
