Just saw that Jim Klauer, EVP over at Costco, dumped 4k shares for like $3.92M recently. Always interesting when you catch these insider moves in the SEC filings, right? The stock was up 2.74% that day at $984, so timing-wise it wasn't the worst exit.

Costco's numbers are actually pretty solid if you look at the fundamentals. Revenue growth hitting 9% is solid for a retail operation, and their debt situation is clean—debt-to-equity around 0.31, way below industry average. But yeah, the valuation is spicy. P/E sitting at like 56, P/S at 1.6, so the market's definitely pricing in some serious future growth.

Thing is, Jim Klauer selling doesn't necessarily mean he's bearish on the company. Could be rebalancing, tax stuff, or just cashing out after a run. The low gross margin (12.5%) is the real thing to watch—that's the trade-off for their bulk model, but it means they're running lean. Anyway, this is the kind of insider activity worth keeping an eye on, just don't read too much into one exec's move alone.
