With the S&P 500 at 7,354 but down 1.6% over five days, and the Russell 2000 flat, Lucas and Luna explore how index funds with market-cap weighting naturally tilt toward the largest companies, and why investors might consider adding a small-cap value ETF to their po...

Lucas and Luna dig into the mechanics: when a bank like JPMorgan buys back stock, index funds are forced sellers or buyers depending on float changes, yet the strategy barely blinks.

Lucas and Luna explore a little-discussed layer of investor protection: how index funds indirectly benefit from FDIC insurance on cash reserves. They unpack a recent Fed stress-test scenario showing banks can absorb $708 billion in losses, and examine why S&P 500 index funds parked at major custodians like BNY Mellon and State Street effectively get a safety net on their cash sleeves. The hosts al...

The Russell 2000 has gained 1.2% over the past five days while the S&P 500 fell nearly 2%. Lucas and Luna dig into what's driving the small-cap outperformance in late June 2026 — and how index fund investors should think about the rotation.

Lucas and Luna break down what Kevin Warsh's 'velvet glove' regime change means for passive portfolios, why small caps are up 1.3% while tech lags, and how dollar-cost averaging keeps you in the game.

They also touch on...

Lucas and Luna unpack a little-known advantage of traditional index funds over ETFs: tax efficiency. With the S&P 500 at 7,501 and markets grinding higher in a low-volatility environment, many investors assume ETFs are always the better choice. But Lucas explains how Vanguard's patented structure and the mechanics of the 'creation unit' process can make traditional mutual funds more tax-friendly....

Lucas and Luna dig into the numbers—S&P 500 at 7,501, Russell 2000 up 1.2% in a week—and explain why the 'great humbling' of stock-pickers is accelerating in 2026. They cite a new Morningstar study showing barely one in four large-cap active funds outperformed their index benchmark over the past five ye...

Lucas and Luna explore how dollar-cost averaging actually works inside index fund portfolios, using the recent volatility around the SpaceX IPO as a lens. They break down the math: a flat market in June 2026 with the S&P at 7,501 means steady accumulation at lower prices beats trying to time the lump sum. They cite real data on the Russell 2000's 0.9% weekly drop, and explain why systematic invest...

The new Fed chair Kevin Warsh is proving more hawkish than markets expected. Lucas and Luna break down what that means for passive investors in June 2026.

Specific data points include the Fed...

The S&P 500 hit 7,501 this week, and the Russell 2000 dropped 0.9%.

Lucas and Luna dig into what the Federal Reserve's June 2026 rate decision means for index fund investors. With the S&P 500 at 7,420 and the Fed holding steady at 3.63 percent, they explore why the removal of cutting bias from the Fed's statement matters more than the hold itself. Lucas explains how passive funds adjust to a 'higher for longer' regime, using the ten-year Treasury yield and sector...

After the Fed held rates steady at 3.63 percent on June 17, 2026, passive index funds have a structural advantage. In this episode, Lucas and Luna explain how the FOMC's new neutral stance changes the math for S&P 500 and total-market funds.

The hosts also discuss the impact of the Fed's ne...
