Lilly Riddle at Daily Upside covered Treasury's choice of State Street's SPDR Portfolio S&P 500 ETF, SPYM, as the default investment for the new Trump accounts, over better-known funds from Vanguard and BlackRock that were also approved. She asked why.
The guiding philosophy for understanding the list is cost, not brand recognition. The Trump accounts law caps investment fees at 10 basis points until the year the child turns 18, and it restricts holdings to broad U.S. equity index funds. What I told Daily Upside: this is not a curated "best of" list. It is a compliance list. Any fund with a higher expense ratio, any leveraged or inverse product, any fund not tracking a broad U.S. equity index was disqualified before anyone weighed brand or performance. SPYM cleared the bar at 2 basis points.
There may be a patriotic footnote, since SPY was the first ETF listed in the U.S. and SPYM is a derivation of it. The open question is whether and when a parent can switch from the default to the other approved funds, and Treasury had not issued guidance on that yet.
The lesson applies to every account you already hold. The fund with the recognizable name is not automatically the right one. The one with the lowest cost that does the job you actually need usually is.
