The Fed Raised Rates to 4%. Here's What It Changes for Your ETFs.
On September 16 the Fed lifted its benchmark rate a quarter point to 3.75-4.00%, its first hike since 2023, and signaled another could follow. For cash sitting in a fund like SGOV, the yield just went up. For a long-term VOO or VTI holder, the honest answer is that almost nothing changed.

What VOO Returned Over 10 Years (and Why It Can Mislead You)
Over the decade through 2024, a fund tracking the S&P 500 like VOO turned roughly $10,000 into about $34,000, near 13% a year. That number is real. It is also one of the most misleading figures in investing. Here is what it hides.

Box-Spread ETFs: Cash That Defers the Tax Bill
BOXX holds no Treasuries and pays no interest, so the return lands in the share price and the tax waits until you sell. The mechanics are real. So is Section 1258, the part of the tax code written for exactly this kind of arrangement, which has never been applied to it.
