RDNT enters the week with a familiar problem: short interest is climbing, the stock is falling, and the analyst who matters most just cut his target for the second time in a month.
Short sellers have rebuilt their position aggressively over the past four weeks. SI % of free float has moved from roughly 12% in mid-April to 14.1% as of May 19 — a 17.9% rise in shares short over the past month. The pace picked up notably after the May 11 earnings print, with short interest briefly touching 14.5% of free float on May 14 before easing fractionally. That four-week build is the dominant positioning story here. The borrow market, however, offers little friction to that trend: availability is a generous 553%, indicating more than five times as many shares available to borrow as are currently shorted. Cost to borrow is minimal at 0.41%. Bears face no structural hurdle to adding.
Options traders have joined the more defensive tone. The put/call ratio jumped to 0.31 on May 19 and 0.42 on May 18, both well above the 20-day mean of 0.13. The resulting z-score of 2.2 makes this a statistically elevated reading — the most pronounced tilt toward puts seen since mid-April. That's a meaningful shift from the preceding three weeks, when the PCR barely moved above 0.10. The combination of rising SI and elevated put demand reinforces the same directional lean.
The Street has been trimming expectations steadily. Barclays analyst Andrew Mok lowered his target to $65 this morning — from $70 a month ago, and from $86 back in November — while holding an Overweight rating. That progressive target erosion from the same firm tells a clear story: conviction in the bull case is weakening even among those who remain positive. The consensus mean target sits at $89.75, implying significant upside to the $53.35 close. However, much of that figure is anchored by older initiations and raises, and the recent direction of travel is one-way down. Bulls point to technology investments, joint venture volume growth, and 100 basis points of margin improvement in advanced procedures. Bears counter with reimbursement risk, labour cost pressure, and an AI segment that has yet to prove financial sustainability. With a PE multiple near 79x and EV/EBITDA of 14.6x — both compressing but still elevated — the valuation leaves little room for execution stumbles. The ORTEX factor score total of 54, with Value the weakest pillar at 28 and momentum sliding from 52 in late April to 45 now, captures this squeeze between stretched multiples and softening price momentum.
The earnings reaction added pressure. The May 11 Q1 print delivered a 3.8% one-day decline and a 6.9% five-day slide. That follows the March 2 print, which rose 4.0% on day one but then gave back 10.7% over the following five sessions. The pattern — initial volatility that resolves to the downside — has become a feature of recent reports rather than an exception. The ORTEX short score of 65.1, which has held between 65 and 67 for most of the past two weeks, places RDNT in the elevated-conviction-short territory without being extreme.
Peer context adds some nuance. Closest correlate NEO fell 4.1% on the week, nearly matching RDNT's 4.7% decline, while OPK gained 4.5% and HQY rose 5.2%. The divergence suggests RDNT's weakness this week is partly sector-driven but partly stock-specific — the earnings overhang and Barclays' second consecutive cut are doing incremental damage that peers without those catalysts avoided.
The next confirmed earnings date is August 7. Between now and then, the question is whether the rate of short-interest build slows as the post-earnings repositioning settles, or whether fresh Barclays target reductions continue to erode the consensus ceiling that has been the primary bull anchor.
