Ambarella, Delphi Automotive, Tellurian Stocks Moving Today

Rate-hike jitters and lower oil prices are weighing on stocks today. Among specific equities in focus are semiconductor stock Ambarella Inc (NASDAQ:AMBA), car tech specialist Delphi Automotive PLC (NYSE:DLPH), and oil-and-gas concern Tellurian Inc (NASDAQ:TELL). Here's a quick look at what's moving shares of AMBA, DLPH, and TELL.

Ambarella Pops on MBLY Tailwinds

AMBA is getting a halo lift today, up 6.3% at $56.11, on a note from analysts at Pacific Crest Securities, which pointed to the company's self-driving vehicle platform in the works, drawing parallels to Mobileye NV (NYSE:MBLY), which is booming higher on M&A news today. Ambarella Inc is up 42% year-over-year, after Friday bouncing from support at the 320-day moving average, which also corresponds with the stock's year-to-date breakeven level. But while analysts have broadly been bullish toward AMBA, options traders have been taking a more skeptical approach. Across the International Securities Exchange (ISE), Chicago Board Options Exchange (CBOE), and NASDAQ OMX PHLX (PHLX), the stock's 50-day put/call volume ratio of 0.94 ranks higher than 91% of all reading from the past year. 

New 12-Month Peak for Delphi Automotive

Also enjoying a MBLY halo lift, DLPH is 3.4% higher at $79.74 today, after earlier tapping an annual high of $80.18. The shares are also rallying on news Delphi Automotive PLC was named one of the "World's Most Ethical Companies" by the Ethisphere Institute for the fifth year in a row. The stock has already added 18.2% in 2017, just off an annual high of $80.18, and the brokerage bunch seems to be expecting even more highs ahead. Out of 16 firms providing coverage, 12 rate the shares a "strong buy."

Tellurian Stock Soars; Catalyst Unclear

Among the top performers on the Nasdaq today, TELL shares are surging 17.1% to $11.69, amid unusually heavy volume. In fact, both stock and options volume are on pace to end the day at 52-week highs. The price action could be a delayed reaction to Friday's news Tellurian Inc selected Societe Generale to create a financial strategy for its liquefied natural gas export project, Driftwood LNG, which is expected to begin construction next year. The past few months have been volatile for TELL stock, with shares making several leaps higher, notching a peak of $21.74 late last month before pulling back sharply. Still, the stock is up more than 900% year-over-year.
