Stocks are lower at midday, as Wall Street struggles to shake off high inflation, and the prospect of aggressive interest rate hikes. The Dow Jones Industrial Average (DJI) is 145 points lower this afternoon -- erasing this morning's modest gains --while the S&P 500 Index (SPX) and Nasdaq Composite (IXIC) are firmly in the red as well. The tech sector is struggling once again, with Google-parent Alphabet (GOOGL) and Microsoft (MSFT) each shedding 1% earlier. Investors are now turning to this week's slew of retail earnings reports, as well as retail sales data.

Options bulls are buying Turtle Beach Corp (Nasdaq: HEAR) today, after the gaming accessory maker gave three board seats to Donerail Group, an investment firm that owns 7.4% of Turtle Beach's outstanding shares.
