California Water Service Group reports Q1 2026 results this morning — and the week heading into the print has been anything but quiet on the positioning front.
Short interest has rebuilt sharply after collapsing through mid-April. SI % of free float dropped to a multi-week low near 1.9% on April 22, then jumped back to 2.6% by April 28 — a 31% weekly increase in shares short. That's not a crowded position by any standard, but the speed of the rebuild is worth noting: roughly 400,000 shares added in three sessions after the mid-April lows. Days to cover, per the most recent FINRA fortnightly report, stand at 3.68 days. The ORTEX short score has drifted higher alongside it, reaching 34.5 on April 28 after sitting below 32 just a week earlier. Cost to borrow is negligible at 0.47%, up 35% on the week from a very low base — borrow supply remains plentiful, with no sign of any squeeze dynamic.
Options positioning tells the opposite story. Call open interest has clearly been outpacing puts, with the put/call ratio at 0.63 — well below its 20-day average of 0.74, and nearly 1.7 standard deviations below that average. That's the most bullish options skew for CWT in recent weeks, sitting closer to the 52-week low of 0.34 than the 52-week high of 2.04. The combination is unusual: fresh short-side rebuilding into an earnings event, while options traders are leaning calls. The divergence suggests these two groups have arrived at different conclusions about today's print.
The Street consensus favors the bulls, with three buy ratings and no sells. The most recent published analyst data points to Wells Fargo holding an Overweight with a $55 target, last adjusted in August 2025 — against the current price of $46.53 that implies meaningful upside. However, this data is over six months old, so readers should note it may not reflect the current view. The last earnings print in February showed the full-year 2025 picture in detail: net income fell to $128 million from $191 million a year prior, and full-year EPS dropped to $2.15 from $3.25. That reset came amid a challenging rate-case environment in California. Factor scores reflect a stock in neutral territory — the 90-day EPS momentum ranks in the 67th percentile, but the EPS surprise score is a soft 30, and the dividend score of 96 stands as the standout: CWT declared its 325th consecutive quarterly dividend just yesterday, which continues to underpin the income case regardless of near-term earnings volatility.
Institutional ownership is tightly held. BlackRock added 233,000 shares to reach 17.8% of shares outstanding, while Amundi's most recent filing shows a 732,000-share addition — the largest incremental institutional move in the top-holder list — taking their position to 5.8% of shares. Vanguard added modestly at 12.3%. Insider activity has been routine: a cluster of small executive sales in March, mostly tax-related compensation vesting, with the CEO selling just 385 shares. Net insider activity over 90 days is technically positive at +12,571 shares, though the value is negligible. None of this tells a directional story heading into earnings.
Closest peer AWR rose 2.1% on the week versus CWT's 0.7%, while WTRG gained 1.1%. The sector drifted modestly higher across the board — a mild tailwind rather than a divergence. The more interesting data point today is the contrast between the short rebuild and the bullish options skew: the Q1 print will quickly resolve which camp reads this right.
