Insiders Buy the Holdings of FNK ETF

Insider buying has been notable among holdings of the First Trust Mid Cap Value AlphaDEX Fund (FNK), with 10.1% of the ETF’s weighted underlying holdings showing insider purchases in the past six months. Examples include CarMax (KMX), a 0.64% position (#51) where two directors filed Form 4s on Oct. 2, 2025 buying 2,000 shares ($45.57) and 10,816 shares ($46.21) respectively, and Silgan Holdings (SLGN), a 0.52% position (#86) where CEO Adam Greenlee bought 7,000 shares ($38.19) on Oct. 31, 2025 and the SVP & chief accounting officer bought 1,000 shares ($38.11) on Nov. 7, 2025; holdings values in the ETF are roughly $1.28m for KMX and $1.04m for SLGN. These Form 4 filings suggest management-level buying in select mid-cap value constituents, a signal market participants may interpret as insider confidence in those companies’ near-term prospects.

Analysis

The First Trust Mid Cap Value AlphaDEX Fund (FNK) shows meaningful insider activity with 10.1% of its weighted underlying holdings reporting insider purchases in the past six months. The article highlights CarMax (KMX) as the #51 holding (0.64% of the ETF) with FNK holding $1,277,809 of KMX; two directors filed Form 4s on 10/02/2025 purchasing 2,000 shares at $45.57 (Mitchell D. Steenrod) and 10,816 shares at $46.21 (Mark F. Oneil); KMX's last trade is reported at $39.03. Silgan Holdings (SLGN) is the #86 holding (0.52% of the ETF) with $1,038,470 position size; CEO Adam J. Greenlee bought 7,000 shares at $38.19 on 10/31/2025 and SVP Kimberly Ulmer bought 1,000 shares at $38.11 on 11/07/2025, with SLGN's last trade at $38.14.

Management-level buying is a positive governance signal and the per-insider purchase values ($91k and $499k at KMX; $267k and $38k at SLGN) indicate meaningful insider conviction at the individual level, but both positions represent modest ETF weights and dollar exposure. Market sentiment tied to these filings is mildly positive (sentiment score 0.25) and reported market-impact is low (0.15), implying limited immediate index-level effect. Investors should treat Form 4s as a directional signal rather than proof of near-term outperformance; the KMX Form 4 purchase prices are materially above the reported last trade, suggesting timing or price context matters. Monitor subsequent filings, company results and price action to validate whether insider buying precedes sustained operational improvement or merely reflects idiosyncratic timing.

Key Decisions for Investors

• Monitor follow-on Form 4s and quarterly results for KMX and SLGN before increasing exposure, as current insider purchases are encouraging but small relative to ETF size
• Consider a modest, research-backed tactical allocation to KMX or SLGN only after confirming improving fundamentals or continued insider accumulation, given FNK holds roughly $1.28m and $1.04m respectively in these names
• Use position-sizing and stop-loss criteria to limit downside since insider buys signal confidence but do not guarantee stock performance, and the reported market-impact is low
