Institutional Ownership Trends

Ameresco, Inc. (AMRC) — Ownership Profile

Institutional ownership of Ameresco, Inc. (AMRC) stands at 62.73% as of 2026Q1, having risen by 3.86 percentage points over the prior quarter. The data indicate a 'distributing' direction, meaning that despite the recent quarterly increase, the broader trend has been net selling by institutions. Over the past ten years, the investor base has contracted to 190 active institutional holders, reflecting a modest decline in the number of participants.

Ownership Overview

AMRC

The current ownership level is well above the lightly‑held threshold (40%) but far below the heavily‑institutionalized mark (90%), suggesting a balanced float with sufficient liquidity. The recent 3.86pp rise does not constitute sustained accumulation, as there have been zero consecutive quarters of increase and two consecutive quarters of decline, indicating that institutional distribution remains the prevailing signal. A reduction in active investors to 190 may modestly tighten the float, potentially amplifying price sensitivity to future buying or selling pressure.

Position Flow Analysis

Ameresco, Inc. (AMRC) — Position Flows

Ameresco, Inc. (AMRC) exhibits a strong net accumulation signal with a current flow ratio of 1.6, surpassing the 1.5 threshold that defines robust inflows. The conviction ratio of 0.68 indicates that existing shareholders are not only holding but also adding to their positions, reinforcing the positive sentiment reflected by the latest net flow of 53, which suggests a notable amount of new buying relative to selling.

Position Flow Metrics

AMRC

The combination of a 1.6 flow ratio and a 0.68 conviction ratio signals that institutions are actively opening new positions while also increasing stakes in existing holdings, pointing to strong confidence in the company's near‑term outlook.

Float & Options Context

Ameresco, Inc. (AMRC) — Float & Options

Ameresco, Inc. (AMRC) exhibits a modest free‑float of approximately 37.3%, derived from an institutional ownership level of 62.7%. This places the float in the "moderate" range—ample enough to support liquidity but not so large as to eliminate the impact of sizable trades. The put/call ratio stands at 0.13, well below the 0.5 call‑heavy threshold, indicating that option market participants are overwhelmingly buying calls relative to puts, a bullish signal that aligns with the relatively high institutional ownership.

Float & Options Overview

AMRC

The extremely low put/call ratio (0.13) suggests strong directional optimism among options traders, likely reflecting expectations of upside price movement rather than hedging activity. With a moderate free float of 37.3%, the share supply can absorb increased buying pressure without triggering severe squeeze dynamics, though any large institutional reallocation could still influence price volatility.

Insider Trading Patterns

Ameresco, Inc. (AMRC) — Insider Activity

Insider activity at Ameresco over the past twelve months has been dominated by selling, with 25 transactions totaling $3,273,176 and no net purchases reported, yielding a buy/sell value ratio of 0.0 (well below the 0.2 bearish threshold). While the CEO, George P. Sakellaris, executed two purchases—25,000 shares on 2024-11-13 and 50,000 shares on 2025-03-04—for a combined $1,161,500, these buys are outweighed by broader insider disposals, and the post‑buy success rate of 50% falls short of the 70% benchmark for well‑timed buying.

Insider Activity Summary

AMRC

The predominance of insider sales suggests routine compensation or diversification rather than a clear bearish signal, given the absence of unusually large or clustered disposals. The CEO’s modest purchases indicate some confidence but are insufficient to offset the overall net selling trend, and the moderate 50% post‑buy success rate provides limited validation of timing.

The strong accumulation flow class and conviction score of 0.68 show net buying pressure despite the distribution flag.
Insider selling is present but not unusually large, resulting in a neutral insider B/S metric.
