iShares Mbs ETF trades on the NASDAQ stock market under the symbol MBB.
As of November 9, 2026, MBB stock price climbed to $92.08 with 7,347,207 million shares trading.

MBB has a market cap of $35.94 billion. This is considered a Large Cap stock.
In the last 3 years, MBB traded as high as $96.97 and as low as $87.87.
MBB has underperformed the market in the last year with a return of +0.9%, while SPY returned +13.4%. This shows that you would have done better investing in the overall market (through SPY) over the last year than in MBB shares. However, MBB has outperformed the market in the last 3 month and 2 week periods, returning +0.1% and +1.2%, while SPY returned -1.8% and -1.0%, respectively. This indicates MBB has been having a stronger performance recently.
MBB support price is $91.75 and resistance is $92.40 (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 MBB shares will trade within this expected range on the day.
