Zeta Global enters the week with its most interesting tension in months: a stock that gained 13% in five days while short sellers are still rebuilding — a tug of war between a post-earnings relief rally and a bear camp that hasn't blinked.
Short interest is genuinely elevated. At nearly 12% of free float, it has eased from a six-week peak of 12.96% touched on May 1 — the immediate aftermath of Q1 results — but the drawdown is measured, not a rout. Bears trimmed roughly 8% of their position from that peak to today's 11.9%, meaning most of the short book is still in place even as the stock clawed back to $18.30. The borrow market offers no particular squeeze trigger: availability is ample at 264%, and cost to borrow has collapsed from a near-term high of 0.64% in late April to just 0.27% — borrowing is cheaper and easier than it has been in months. That combination means new shorts can be added with minimal friction, and existing ones face no urgency to exit.
Options positioning tells a subtly more cautious story than the call-heavy tone of the past month. The put/call ratio has ticked up to 0.35 — modestly above its 20-day average of 0.32 — sitting about 1.4 standard deviations above recent norms. That is not a panic reading (the 52-week high is 0.64), but the direction of travel after the Q1 print is worth noting. Options traders are quietly adding a little more downside protection even as the stock rallies.
The Street is split but tilting constructive. B of A Securities reinstated coverage on May 19 with a Buy and a $24 target — a meaningful data point given the timing, right as the stock fades 4.6% on the day. That follows Keybanc's upgrade to Overweight at the end of April and RBC raising its target to $29 after Q1 results. Against that, Goldman and Morgan Stanley hold Neutral and Equal-Weight respectively, and their tone has been more cautious on valuation. The consensus mean target of $28.31 implies 55% upside to current levels — bullish on paper, but the bull case rests on AI-driven revenue visibility and cross-selling execution, while bears point to low-margin, non-owned channel dependence and usage-based contracts that cap cash flow expansion. EV/EBITDA is running near 10x, down roughly 0.9 points over the past month, as the market has slowly re-rated the multiple lower since the peak in April. Forward EPS growth ranks in the 90th percentile of the universe — that is the genuine source of conviction for buyers.
Institutional ownership adds an interesting wrinkle. Greenvale Capital added 3.4 million shares in Q1, Capital Research added just over 3 million, and Jane Street built a 3.3 million share position — three meaningful buyers in a single quarter. BlackRock also added 1.2 million shares through April. Founder and Chairman/CEO David Steinberg holds 10.2% of the company, providing alignment but also a standing overhang. The most recent insider transaction on record is a $75,000 director sale in March — small enough to be noise.
The Q1 earnings print on May 5 ended with the stock down 6.7% on the day and off nearly 12% over the following five sessions — the sharpest negative reaction in the recent history. The April 30 call, by contrast, produced a 4.4% first-day gain before fading 3% across the week. The pattern across recent prints is one of short-lived pops followed by drift, which maps onto the bear case about execution risk in a competitive market.
What to watch: whether short interest resumes its April build toward 13% of free float now that borrow is cheap and easy, or whether the B of A reinstatement and peer momentum from RAMP (+31% on the week) pull more buyers into the name first.
