TDC just posted its strongest weekly move in months — up 17% — yet short sellers are adding, not retreating.
The stock closed at $30.08 on Tuesday, gaining 2.6% on the day and nearly 17% across the week after Teradata's Q1 2026 results came in ahead of estimates on both earnings and revenue. The headline beat looks clean. Full-year guidance also landed, with management projecting 2%–4% ARR growth for 2026. For a stock that had been grinding lower for months, the relief was palpable. What makes this week unusual is what's happening underneath: despite that 17% pop, short sellers have continued to build positions rather than cover.
Short interest has climbed to approximately 16.8% of free float — up from 13% in mid-March and now running at its highest level of the past six weeks. That is a sustained, deliberate build, not a blip. Over the last month, estimated short shares rose nearly 26%. Days to cover from the latest FINRA fortnightly report stand at 7.9 days, meaning any meaningful covering wave would take over a week of full average volume to clear. Borrow cost remains inexpensive at around 0.52% annualised — barely moved from where it was seven weeks ago — which tells you the demand for shorts is not yet straining the lending pool. Availability is also generous, with the borrow market nowhere near tight. This is a position the shorts are building at leisure, not under pressure.
Options tell a strikingly different story. The put/call ratio collapsed to 0.14 on Tuesday — more than three standard deviations below its 20-day average of 0.29, and one of the most call-heavy readings of the past year (the 52-week low was 0.05). That level signals aggressive call buying, almost certainly driven by investors chasing the earnings pop. The divergence is stark: options traders were positioned bullishly into the number, while short sellers were quietly adding exposure. Both camps cannot be right over the medium term.
On the Street, the picture is mixed but tilting cautious. Barclays analyst Raimo Lenschow — who has maintained an Underweight for months — lowered his target to $28 this morning, now sitting below the current price of $30.08. That is a direct shot across the bow: one of the most consistent bears on the name is now calling for downside from current levels even after the beat. Citi's desk trimmed its target from $42 to $38 in late April while keeping a Buy, suggesting the bull case is intact but the ceiling has come down. The mean price target across analysts sits at roughly $33, implying modest upside from here. The EPS surprise percentile rank of 94 says Teradata has a strong history of beating estimates — a genuine bull-case data point. The bear case, as articulated by the likes of Barclays, centres on the structural drag from a cloud transition that is still fighting margin headwinds and a competitive landscape in data platforms that grows tougher by the quarter. The 2026 ARR growth guide of 2%–4% is modest — below what several analysts had modelled — and the EV/EBITDA of around 6x reflects a market that has already priced in considerable scepticism about the pace of recovery.
Institutional ownership adds one more wrinkle. Fuller & Thaler Asset Management appears to have initiated a full position — their last reported change shows they went from zero to 2.2 million shares as of February. Lynrock Lake, meanwhile, remained the third-largest holder at nearly 10% of shares with a marginal trim. The CEO, Stephen McMillan, sold over $3.4 million of stock across three transactions in early March — right around the $28–$31 range where the stock trades today. Those sales were planned and sized at levels very close to where shares sit now, which the Street will likely note in assessing how management views fair value.
The next confirmed earnings event is scheduled for May 14. With short interest still rising, call positioning elevated, Barclays openly calling for a pullback, and the stock now back to levels where the CEO was a seller in March, the coming week's trading will test whether Tuesday's buyers find follow-through — or hand the shorts their entry.
