The Dow Jones Industrial Average (DJI) is 293 points higher midday, thanks in part to upbeat earnings from Microsoft (MSFT). The blue chip's quarterly win is providing a much-needed shot in the arm to tech and chip stocks, helping both the S&P 500 Index (SPX) and Nasdaq Composite (IXIC) brush off a rising 10-year Treasury yield.

Amid all of this positive price action, the Cboe Volatility Index (VIX) is on track to snap a six-day win streak. All eyes are now on the Federal Reserve's announcement later today, with traders hoping to decipher the central bank's next moves. 

EQT Corporation (NYSE: EQT) is seeing an unusual amount of bullish options activity today. So far, 35,000 calls have already crossed the tape -- 32 times the intraday average -- compared to just 44 puts. Most popular is the March 23 call, followed by the 22-strike call in the same series, with new positions being opened at the former. EQT IS up 1.6% at $20.43 at last check and boasts a 28.4% year-to-date return.

Clean Energy Fuels Corp (Nasdaq: CLNE) is near the top of the Nasdaq today, last seen up 14.3% at $6.30. Today's pop came after the company signed an agreement to build a methane capture digester for Millenkamp Cattle, a dairy farm in Idaho. CLNE is bouncing off a Jan. 24 annual low of $4.70, while pacing for a close above the 40-day moving average for the first time since November. The equity is still down 44.6% year-over-year, though.

Towards the bottom of the Nasdaq is Mainz Biomed BV (Nasdaq: MYNZ), last seen down 26.6% at $14.87 at last check, after the company yesterday priced its underwritten public follow-on offering of 1.5 million ordinary shares at $15 per share. The Wall Street newbie is cooling off from a Jan. 18, record high of $20, after going public in November with an initial public offering (IPO) price of $5 per share. Quarter-to-date, MYNZ is up 44.7%.
