US stock futures were leaning forward in the premarket session as traders mull interest rates that appear to be stabilizing after certain benchmark yields, such as those on 10-year US Treasuries, hit one-year highs earlier in the week. Optimism that an end to the COVIID-19 pandemic is in sight is also high following the release of official federal data that showed 78.2 million vaccine doses have been administered in the US as of March 2. The Biden administration also said Tuesday that every American can be inoculated by June.
