ArcBest Heads Into Earnings With Shorts Building and Options Turning Bullish

ArcBest reports Q3 results on November 6 with two months of rising short interest pulling against one of the more optimistic options setups in the stock's recent history.

Short sellers have been methodical in their rebuild. Short interest as a percentage of free float has climbed to 7.1%, up 28% from a month ago and 2.6% higher on the week alone. The sharpest step-change came in mid-October, when shares short jumped from roughly 1.13 million to 1.47 million in a single session on October 9, and have kept rising since. Despite that build, the borrow market remains uncrowded. Availability is at 804%, meaning lenders hold roughly eight shares available for every one currently borrowed, comfortably above the 52-week low of 450%. Cost to borrow has eased 15% over the past week to 0.44%, near the low end of its recent range. The borrowing infrastructure for a bigger short push exists, but it isn't being used aggressively yet.

Options traders are reading the situation differently to the shorts. The put/call ratio has dropped to 0.32, well below its 20-day average of 0.40 and sitting closer to the 52-week low of 0.11 than the high of 1.48. That gap between the PCR and the recent average is roughly 0.65 standard deviations below the mean, a moderate lean toward calls rather than puts. Traders are not hedging into this print. They are positioning for the upside case.

The Street broadly shares that optimism, though the conviction has softened. Three firms, Stifel, Citigroup, and Truist Securities, all trimmed targets in early October while maintaining Buy ratings. The cuts landed between $2 and $17, pulling the consensus mean target to around $167 against a current price of $134.48, implying roughly 24% return potential. That is a wide gap, but it has been there before. Valuation remains moderate: the stock trades at a PE of 14.7 and EV/EBITDA of 7.4. The forward earnings picture is striking: the eps_12m_fwd_yoy_increase factor ranks in the 95th percentile across the universe, meaning analysts expect substantial earnings growth over the next twelve months. The EPS surprise score, by contrast, sits at just the 2nd percentile, a reminder that the company has missed expectations more often than not. The bull case rests on improving LTL pricing, the Asset-Light segment turning profitable, and tighter truckload capacity feeding through to margins. The bear case centres on macro sensitivity, labor cost exposure, and the risk that estimates drift lower if freight demand softens.

One institutional angle is worth flagging. Invesco added 852,878 shares in the quarter to September 30, lifting its stake to 6.9% of shares. American Century added 160,701 shares to reach 6.9% as well, and FMR (Fidelity) filed a 13G/A in August showing a sharp reduction from 5.8% to just 0.6%. All are passive holders on 13G filings, with no activist on the register. Insider activity over the past 90 days has run net negative: sales of roughly $3.2 million, with the Chief Innovation Officer selling into August strength near $135 and two directors following. No open-market purchases appear in the recent record.

One adjacent data point stands out. Retail attention is unusually elevated: the ORTEX alt data layer recorded a Wikipedia-views z-score of 6.0 as of October 19, well above normal. That reading measures attention relative to the stock's own 90-day history, not a revenue indicator, but it suggests ArcBest is drawing more interest than usual in the weeks ahead of its print.

ARCB rose 3.2% on the week, bucking most of its peer group. SNDR fell 5% and ODFL dropped 5% over the same period, while XPO added 1.7%. The relative strength is notable given that the broader LTL group was under pressure. The last comparable earnings event, July 31, saw the stock fall 3.2% the day after and 3.0% over the following five days.

The November 6 report is the next hard test: whether the improving margin narrative from the bull case has translated into numbers, and whether a short position that grew 28% in a month is positioned for disappointment or carrying too much risk into an options market that is clearly not.
