[SCHEDULE 13G/A] DoubleLine Multi-Sector Income ETF SEC Filing

Rhea-AI Filing Summary

Foundations Investment Advisors, LLC has filed Amendment No. 3 to Schedule 13G disclosing its beneficial ownership position in DoubleLine Multi-Sector Income ETF (CUSIP 25861R501, symbol DMX) as of 30 June 2025.

• Shares owned: 608,483.
• Percent of class: 80.1%.
• Power: Sole dispositive authority over all shares; no voting power reported (both sole and shared voting power = 0).
• Filer status: Registered Investment Adviser (IA) organized in Arizona.
• Signature: Marc Pugsley, CCO, dated 08 July 2025.

The filing indicates that a single investment adviser controls a dominant share of the ETF’s outstanding units. Such concentration can materially affect float availability and secondary-market liquidity, even though the filer retains no formal voting influence over fund governance. Investors should monitor any future changes that could alter the ETF’s ownership structure or market dynamics.

Positive

• Significant commitment: Foundations Investment Advisors holds 80.1% of DMX, indicating strong institutional support.
• No voting control: Absence of voting power mitigates immediate governance concerns despite large ownership.

Negative

• High concentration risk: A single holder controls 80.1% of outstanding shares, potentially reducing free float and liquidity.
• Market impact potential: Sole dispositive authority means sizeable redemptions could trigger price volatility.

Insights

Portfolio Manager

TL;DR: 80% stake by one adviser makes DMX liquidity highly dependent on a single holder.

The 608,483-unit position reported by Foundations Investment Advisors equals 80.1% of DMX’s outstanding shares. With sole dispositive but zero voting power, the adviser can technically exit or resize the position at any time, potentially creating price volatility or liquidity gaps. Conversely, its continued ownership offers price support and signals conviction in the fund’s strategy. Overall, the disclosure is material but not inherently bullish or bearish; liquidity risk merits close watch.

Corporate Governance Expert

TL;DR: High ownership concentration without voting rights reduces governance influence but raises float risk.

From a governance standpoint, the filer’s lack of voting power limits its direct control over ETF decisions, preserving the trustee’s autonomy. However, controlling 80% of the units concentrates market power in the filer’s hands; any large-scale redemption could disrupt pricing mechanisms. Regulators typically monitor such structures, but no breach is implied here. The situation is impactful mainly for market microstructure rather than governance.
