Methodology note: these Smart Money cards use consecutive 13F disclosure snapshots, not trade-by-trade execution data. "Buying", "selling", "new holders", and "trimmed" refer to quarter-over-quarter changes in reported holders, aggregate shares, or disclosed position values between filings. They are useful for ownership regime analysis and crowding, but they do not imply exact trade timing on the filing date.

Buying streak — 1 quarter in a row: For 1 consecutive quarter, more hedge funds added AMSC than sold it. That's a consistent pattern of professional buying — not a one-time trade. When institutions keep buying quarter after quarter, it usually means they see a multi-year opportunity, not just a short-term momentum flip.
Slight buying edge — 58% buying: Last quarter: 155 funds bought or added vs 112 that reduced or exited. It's nearly a 50/50 split — some institutions are convinced, others are taking profits. This mixed picture is normal near price highs.
Strong quality — 39% AUM from major funds: 46 of 243 holders rank in the top 100 by AUM, accounting for 39% of total institutional value held. A meaningful share of the ownership value comes from the most well-resourced institutions.
47% of holders stayed for 2+ years: 114 out of 243 hedge funds have held AMSC for over 2 years without selling. Long-term investors are generally harder to shake out during market stress, creating a stable ownership base that limits the risk of sudden capitulation.
As of today, AMSC has moved -30.7% since the 2026 Q1 13F filing date (May 15, 2026), compared to +3988.2% for the XLI sector ETF — an outperformance of -4018.9%. Since the quarter end (March 31, 2026), AMSC has gained +11.4% vs +4.9% for XLI. The stock is tracking its sector benchmark closely. The signal remains fresh and the entry point is still near the fund's implied reference.
