Short sellers added heavily to positions in NSC over the past week. The increase is sharp and worth watching. The lending market, however, tells a different story.
Estimated short interest in Norfolk Southern rose 34% over the seven trading days to September 30, climbing from roughly 5.6 million to 7.6 million shares. At 3.4% of free float, the absolute level is not extreme. But the speed of the move is unusual. Almost the entire increase landed on a single day: September 23, when shares short jumped by about 2 million in one session.
The ORTEX short score picked up the change. It stood at 36.2 on September 22, then climbed to 40.6 by September 24 and reached 41.0 by September 29. That four-point move reflects the sudden repositioning.
Despite the jump in positions, nothing in the lending market suggests stress. Availability stands at 9,999%, the highest the ORTEX system records, meaning shares available to borrow vastly outnumber shares already borrowed. Cost to borrow is 0.30%, negligible for a large-cap equity. These figures have barely moved through the period when short interest was rising. Establishing or extending a short position in NSC right now carries almost no execution cost.
Wikipedia page views and ORTEX stock page traffic combined to a z-score of 2.73 above the 90-day average as of September 28, a signal of elevated retail attention. It is a measure of interest, not a revenue indicator, but it adds to the picture of heightened activity around the stock.
In options, the put-to-call ratio has dropped sharply. The PCR sat at 2.14 in August and has fallen to 1.30 as of September 30, now 1.95 standard deviations below its 20-day mean. That means call positioning has grown relative to puts over the same window that short interest was rising, an unusual divergence between two groups of market participants.
The consensus price target sits at $363.50 against a closing price of $309.00 on September 30, a gap of roughly 18%. After Q2 results in July, BMO Capital, Baird, Citi, JP Morgan, TD Cowen, Wells Fargo, RBC Capital and Barclays all raised their targets, though most kept neutral or hold-equivalent ratings. The stock has pulled back 11% over the past month.
Earnings are scheduled for October 23. The bear case centres on coal pricing pressure, intermodal volume losses tied to merger competition, and macro uncertainty in vehicle production. The bull case rests on improving operating ratio, a tightening truck market that supports pricing, and rising EPS estimates for 2026 and 2027.
The September 23 spike in short positions is the key data point. With availability effectively unlimited and cost to borrow near zero, the position can be held cheaply. Whether it gets covered or extended will likely depend on the October 23 earnings print, now 22 days away.
