ProShares UltraPro Short QQQ ETF (NASDAQ:SQQQ) shares are trading higher by 1.1% amid overall market weakness and recent strength in Treasury yields. The ETF is designed for short-term trading and market timing strategies. It is particularly relevant to the technology sector as the NASDAQ-100 Index is heavily weighted toward technology and growth-oriented stocks. Rising interest rates can lead to higher discount rates applied to future cash flows, potentially reducing the present value of future earnings for tech companies, which can benefit SQQQ.
