EnerNOC, Inc. (ENOC) is surging on an energy collaboration with Tesla Motors Inc (TSLA)
EnerNOC, Inc. (NASDAQ:ENOC) is jumping on a
new energy-storage partnership with Tesla Motors Inc (NASDAQ:TSLA) -- part of the latter's
expansion into home energy systems. At last check, ENOC was 21.5% higher at $13.43, and calls are flying off the shelves at 42 times the normal intraday rate.
Digging deeper, the stock's May and June 15 calls are each seeing buy-to-open activity. In other words, these speculators think ENOC will topple $15 by the respective expiration dates -- at the close on Friday, May 15, and Friday, June 19. The equity hasn't hit this mark since late February, following a post-earnings bear gap.
On the sentiment front, short-term option traders have been unusually put-skewed of late. ENOC's Schaeffer's put/call open interest ratio (SOIR) of 2.25 indicates put open interest more than doubles call open interest among options expiring in less than three months. What's more, this SOIR ranks in the 96th percentile of its 52-week range.
Elsewhere, short sellers may be getting nervous. Roughly 9% of EnerNoc, Inc.' (NASDAQ:ENOC) is float is sold short, which would take more than four sessions to repurchase, at the stock's average trading levels.
