Costco's 0.37% Rise Places Stock 46th in Trading Volume Ahead of Earnings

On September 12, 2025, Costco Wholesale Corporation (COST) closed with a 0.37% gain, trading at $338.50. The stock recorded a trading volume of 1.41 billion shares, ranking it 46th in market activity for the day. The performance followed mixed investor sentiment ahead of the company’s upcoming quarterly earnings release scheduled for September 18.

Analysts highlighted renewed focus on Costco’s membership growth and inventory management strategies amid ongoing inflationary pressures. Recent reports indicated the retailer maintained its premium pricing model while expanding digital services, which could bolster long-term margins. However, concerns lingered over potential deceleration in discretionary spending, particularly in the U.S. market, where same-store sales growth has slowed compared to prior quarters.

Short-term technical indicators showed the stock remained within a consolidation pattern after hitting a 52-week high in late August. Institutional buying activity intensified in the week leading up to the earnings event, with several large-cap funds adding to positions ahead of key data points. The broader retail sector also saw increased volatility as investors weighed macroeconomic risks against sector-specific resilience.

I understand the idea: each trading day you want to form a portfolio consisting of the 500 stocks with the highest trading volume, hold that basket for one day, then re-balance the next day, and measure the cumulative return from 2022-01-01 to today. At the moment, the back-testing tools that are available to me can only process one security (ticker) at a time. They don’t yet support universe-wide ranking, portfolio formation, and daily rebalancing across hundreds of names. To move forward, we could do one of the following: 1. Narrow the scope—for example, test the strategy on a single broad-based ETF (such as SPY or QQQ) to see how a “trading-volume” filter would have performed if applied to that ETF only. 2. Test on a small, user-supplied list of tickers (e.g., 10–20 stocks) so we can at least illustrate the mechanics. 3. Wait until multi-asset portfolio back-testing capability is added and revisit the full strategy then. Let me know which option (or another approach) you’d like to try, and we’ll proceed accordingly.
