S3 BLACKLIGHT: Alpha for Plug Power Shorts About to Take a Hit

Conviction to short Plug Power (PLUG US), the fuel cell and hydrogen renewable energy developer, continues to hold steady throughout September.  With stock borrow cost spiking to 75% fee today, short sellers have not covered their positions even as PLUG stock price rebounded 17% off the year to date low of $1.36 hit last week.

According to the S3 Velocity Indicator, a measure of the real-time relative change in shorting activity, the 7 day trend line is up 13% since the beginning of the month, suggesting short sellers continue to take advantage of any supply that becomes available to borrow.   The majority of the top 10 institutional holders who actively participate in lending programs have added to their longs as of 6/30, increasing the amount of total borrow liquidity to be sold short.   Current short interest is now estimated to be as high as $60 million, an exposure not seen since April.

With shares on loan compared to total lendable supply currently near 100% utilization, short sellers have yet to pull the “plug” on their bearish bets.  However, existing shorts should prepare for inevitable rate changes on their “power” play, cutting into alpha generation.
