Ameren Corporation arrives at its July 31 earnings release with the short-side story running in reverse — the aggressive position-building that defined the past month has unwound sharply in just the last few days.
The shift is notable. A prior note flagged short interest climbing to roughly 5.4% of the free float and 14.5 million shares by mid-July — one of the fastest builds in recent data for a regulated utility. Since then, bears have retreated just as quickly. Short interest has dropped 15% over the past week to 4.5% of the free float, with an 8% single-day fall on July 24 alone. At 12.2 million borrowed shares, the position is back toward where it started the month. The borrow market remains unconstrained throughout: availability is running at over 2,100% — far above any level that would indicate squeeze risk — and the cost to borrow is a negligible 0.51%. Shorts are unwinding not because they are being forced out, but apparently by choice ahead of the print.
Options traders are leaning the same direction. The put/call ratio has dropped to 0.24, well below its 20-day average of 0.32 and nearly a standard deviation light on the bearish side. Call activity is dominating, consistent with a market that is positioning for a benign or positive outcome rather than hedging for a miss. That marks a reversal from the more cautious options tone evident in mid-July, when the ratio briefly moved above 0.45.
Analyst activity into the print has been broadly constructive. Keybanc upgraded AEE to Overweight on July 23, adding a fresh $122 target. Morgan Stanley raised its target to $118 on July 22, while JPMorgan lifted its target to $137 — the most bullish on the Street — in mid-July. BMO Capital trimmed its target modestly to $119 but kept its Outperform rating. The consensus mean target of $121.44 sits about 8% above the current price of $112.11, suggesting the Street sees room to recover from a month that has cost the stock roughly 5%. Bulls point to 3% retail sales growth across all customer classes at Ameren Missouri and steady year-over-year earnings improvement. Bears flag headwinds from weather normalization, modest rate-case contributions, and potential dilution from share issuance under forward sale agreements.
Past earnings prints offer a consistent pattern worth noting: the last three results each produced a fall of roughly 2.5% on the day, though the five-day reaction was mixed. The stock fell 1.5% on the day but has rebounded 1.5% over the past week heading into the release.
Overall, positioning has shifted from conspicuously bearish to comparatively neutral: the shorts who built aggressively through mid-July have largely stepped back, options favor calls over puts, and analyst targets cluster above the current price. Thursday's print will test whether the underlying demand and rate-recovery story is strong enough to break the pattern of modest post-earnings disappointments.
