ATO Bears Step In After JPM Downgrade

Three distinct signals have converged on ATO since mid-September. Short sellers added positions aggressively, options traders leaned bullish, and the cost to borrow doubled. The trigger is clear: JP Morgan's downgrade.

Analyst Pressure Started It

JP Morgan's Jeremy Tonet downgraded ATO to Neutral on September 11. The price target fell to $180 from $198. One week later, Morgan Stanley's Stephen Byrd cut his target to $179 from $190, maintaining Equal-Weight. Truist Securities had already trimmed to $179 in August. The consensus target sits at $185.55. The stock trades at $158.27. That gap looks wide, but all recent moves point the same direction: down.

Short Sellers Respond

Short interest jumped 21.5% in the week following the JPM downgrade. It now stands at 2.78% of free float — 4.49 million shares. That is the strongest single-week build since early September. Over the past month, short positions have grown 34.4%.

The absolute level is not extreme. But the pace of accumulation is notable for a regulated gas utility.

Borrow Cost Doubles

The cost to borrow ATO shares rose 103% over the past week, reaching 0.53%. On September 14 it was 0.26%. That is a rapid move for a stock in this sector.

Importantly, borrowing remains plentiful. Availability sits at 3,132% — roughly 31 shares available for every one already lent out. The lending pool is not constrained. Short sellers facing the current stock slide are not under squeeze pressure.

Options Tell a Different Story

The put-call ratio is 0.44, below its 20-day mean of 0.46. Options traders are not piling into puts. Calls dominate the flow. November 4th earnings sit six weeks out. Some buyers may be positioning for a recovery into results.

What to watch: Whether short interest continues to build toward earnings, or whether the 15%+ analyst upside gap attracts dip buyers first.
