Stocks are confidently higher midday, as investors step back into tech names and put Wall Street on track to close a choppy week on a high note. The Dow jumped more than 900 points and is eyeing its best single-session gain since May 12, with the blue-chip index heading for a weekly win. The S&P 500 and Nasdaq are both up over 1%, lifted by rebounds from tech heavyweights Nvidia (NVDA) and Microsoft (MSFT). Even with today's stabilization, both indexes are still in the red for the week

Options traders are piling in on Mineralys Therapeutics Inc (Nasdaq: MLYS). At last check, over 92,000 puts have changed hands -- 50 times the average intraday amount. The most popular contract is the March 25 put, with new positions being bought to open. The biotech stock is up 3.4% to trade at $29.20, at last glance and boast a 192.5% year-over-year gain.

Robinhood Markets Inc (Nasdaq: HOOD) is one of the top performers on the Nasdaq today. Although the catalyst remains unclear, shares are now up 12.7% to trade at $81.92, at last check, adding to its 53.4% year-over-year gain. HOOD is poised to snap an eight-day losing streak that featured a seven-month low of $71.87 yesterday.

Atlassian Corp (Nasdaq: TEAM) is one of worst names on the Nasdaq today, falling victim to a dismal third-quarter outlook that overshadowed the software company's second-quarter top-line beat. TEAM is 3.4% lower at $95.06 at last look and earlier hit a 7-year low of $92.70. Shares are down 70.4% over the past 12 months and have faced stiff pressure from their descending 120-day moving average.
