This technical setup and positioning suggest a potential for a short squeeze, indicating further upside for the equity.

Analysis

Zscaler (ZS) is exhibiting a strong bullish technical setup following its late-May post-earnings rally. The stock has successfully broken out and retested the $304 level, a significant mark that represents 19 times its initial public offering price, suggesting this former resistance may now act as firm support. The primary catalyst for further upside is a potential short squeeze, evidenced by short interest reaching an all-time high, with 9% of the stock's available float sold short and a cover ratio of three days. This considerable bearish positioning is occurring alongside positive price action, creating pressure on short sellers. Compounding this setup, implied volatility is at a historical low, sitting 92% below its annual readings, which makes options relatively inexpensive. The derivatives market shows significant put open interest at the 290 and 310 strikes, with total put OI nearly equaling total call OI, indicating a high level of bearish bets or hedging that could be forced to unwind, further fueling an upward price move.

Key Decisions for Investors

• Given the confluence of a technical breakout above $304 and an all-time high in short interest, investors could consider a tactical long position to capitalize on a potential short squeeze.
• The historically low implied volatility presents an opportunity to use call options for leveraged upside exposure, though this strategy carries inherently higher risk and is best suited for investors with a high risk tolerance.
• Traders should use the $304 level as a key risk indicator; a sustained drop below this price would invalidate the immediate bullish thesis and signal a potential reversal.
• Recognize that this trade is driven by market technicals and positioning rather than new fundamentals; the high short interest also reflects significant underlying bearish sentiment, which remains a key risk.
