Long And Short Of Short Interest

posted in: Equities, Technicals | 0

Here is a brief review of change in short interest in the November 1-15 period in nine S&P 500 sectors (by time of publication, short interest for the Nasdaq and the NYSE Group has not yet been published).

Of the nine, short interest rose in six p/p (XLF, XLI, XLK, XLP, XLU, XLY).  Five were above their respective 50-day moving average (XLB, XLE, XLF, XLI, XLY) and four below (XLK, XLP, XLU, XLV).xlb

XLB (SPDR materials ETF) – short interest ↓ 8.2% p/p, ETF ↑ 3.7%

On November 3, XLB found support at the lower Bollinger band, and never looked back, further bolstered by the Trump rally; resistance at $49-plus stopped the advance during the period.  This probably led shorts to not give up completely.  Short interest was down but not huge.xle

XLE (SPDR energy ETF) – short interest ↓ 0.5% p/p, ETF ↑ 4.7%

Since April this year, XLE has been trading within an ascending channel.  Early this month, it found support at the lower end of that.  This should have caused shorts to cover.

With that said, short interest was already suppressed.  Shorts got squeezed big time as XLE bottomed in January this year, and they have been hesitant since.  Rightly so, as the ETF rallied big during the reporting period.xlf

XLF (SPDR financial ETF) – short interest ↑ 7.9% p/p, ETF ↑ 12.4%

Of the nine sectors, XLF rallied the most during the period.  The November 9th jump forcefully pushed it past resistance at $19-plus, which goes back nearly two years – or can be extended as far back as March 2004.  The ETF ($22.41) is still below the all-time high $25.51 it reached in May 2007, but November has produced a tall, white candle.

Going into this, shorts had been hesitantly adding.  Although the current level of short interest is nowhere near the level from early this year.  Importantly, the massive rally in XLF did not dissuade shorts from adding more.xli

XLI (SPDR industrial ETF) – short interest ↑ 1.7% p/p, ETF ↑ 7.6%

Before the Trump effect could do its magic, XLI early this month defended horizontal support at $56-plus extending back to February last year.  Then came the November 9th surge, past a declining trend line from the middle of August this year.

Short interest was already suppressed going into this.  The rally was not caused by a squeeze.xlk

XLK (SPDR technology ETF) – short interest ↑ 58% p/p, ETF ↓ 1.6%

The ETF started the reporting period by losing the 50-day moving average.  The November 9th rally was followed by a higher-volume red engulfing candle.  Shorts have apparently taken this as a sign of weakness.  Notice the surge in short interest!

Tech stocks have underperformed – relatively – post-Trump victory.  The Nasdaq composite was only up 1.7 percent.  And the Nasdaq 100 was down 0.8 percent, which is what XLK followed.xlp

XLP (SPDR consumer stables ETF) – short interest ↑ 10.3% p/p, ETF ↓ 3.9%

The ETF represents one of the sectors that have been on the receiving end post-Trump win.  Leading up to this, XLP had been hovering around the 200-day moving average, which it tried to rally past on the 8th but the attempt was vehemently rejected at the 50-day.  Once the election results were out, the ETF got slammed.

Interestingly, rather than locking in profit, shorts piled on.  This could potentially be a source of squeeze once interest rates peak, and money begins to shift toward high dividend yielders.xlu

XLU (SPDR utilities ETF) – short interest ↑ 36.8% p/p, ETF ↓ 5.4%

Another one of those sectors that was taken to the woodshed post-election.  XLU lost both 50- and 200-day moving averages.  As is the case with XLP, shorts used this as an opportunity to add to.  A squeeze waiting to happen in due course?xlv

XLV (SPDR healthcare ETF) – short interest ↓ 19.2% p/p, ETF ↑ 4.6%

Going into this, XLV was increasingly pricing in a Clinton victory, as it had been under pressure since early August.

Despite this, shorts were not too aggressive.  Tough to say if they sensed something or it was sheer luck.  But those that stayed short got squeezed, as post-election the ETF, which closed the period at $70.47, rallied as high as $72.08.xly

XLY (SPDR consumer discretionary ETF) – short interest ↑ 3.5% p/p, ETF ↑ 2.5%

The ETF lost the 200-day moving average early on during the period, but its fortunes quickly did a 360 thanks to the election results.  Both 50- and 200-day moving averages were recaptured.  To boot, a two-month downtrend line was taken out as well.  Shorts are betting – albeit not too aggressively – that the rally is not going to last.
