Here's an interesting pattern worth noting: when looking at IB (Initial Balance) - the high and low established within the first trading hour - Costco shows compelling data. The stock's IB range sits between $896.03 and $930.87, and historically? This range gets broken roughly 95% of the time on Thursdays. That's a pretty significant breakout frequency for day traders watching intraday moves. Right now, Costco is setting up as a potential play for those tracking IB breakout strategies. The statistical edge here is noteworthy - nearly perfect consistency suggests strong directional momentum once that range yields.
