Is the S&P 500 all it's cracked up to be? Derek and Kelly break down everything you actually need to know about the most popular investment on the planet — what it is, why everyone recommends it, and why "just buy the S&P 500" isn't the complete answer.
They cover how the index actually works (spoiler: it's not an equal split of 500 companies), why passive investing changed the game, the "Lost Decade" that nobody talks about, and the tax stuff that quietly eats your returns if you're not paying attention. Plus — fractional shares, the real barrier to entry for new investors, and why leaving money in cash inside your retirement account is a mistake more people make than you'd think. This is the episode for anyone who's Googled "where should I invest my money" and gotten the same three-word answer every time.
