Levi Strauss Shares Plummet 12.55% on 110.75% Volume Surge Ranks 362nd in Trading Activity
On October 10, 2025, Levi Strauss & Co.LEVI-- (LEVI) closed with a 12.55% decline, marking its largest single-day drop in over three months. The stock traded with a volume of $350 million, a 110.75% increase from the previous day, ranking it 362nd in volume among listed equities. The selloff occurred amid renewed investor caution in the apparel sector following mixed guidance from key rivals and broader market volatility in consumer discretionary stocks.
Analysts noted the decline was exacerbated by technical selling pressure after the stock broke below key support levels established during its summer rebound. While no material company-specific news was released, sector-wide concerns about seasonal demand for fall collections and inventory management practices at peer retailers contributed to the downturn. The stock's underperformance was further amplified by its position in high-turnover baskets, as institutional rebalancing activity accelerated during the session.
To run this back-test robustly I need to pin down a few implementation details: 1. Market universe • Is this meant to be only U.S.–listed common stocks (NYSE + NASDAQ), or another universe? • Should we exclude ETFs, preferreds, SPACs, etc.? 2. Ranking & re-balancing rule • “Top 500 by daily trading volume” – we will rank each day on the same-day dollar volume and then buy an equal-weighted basket of the 500 highest-ranked names. • Trade timing: buy at today’s close, sell at tomorrow’s close (1-day holding), then form a new basket. Is that acceptable? 3. Transaction assumptions • Slippage / commission: do you want to include a per-trade cost (e.g., 1 bp each side) or ignore trading costs? 4. Practical simplifications Holding 500 stocks daily for nearly three years involves ~900 trading days × 500 positions ≈ 450 k round-trips. I can still compute it, but please confirm you’re comfortable with an equal-weight implementation and no position-size limits. Once these points are confirmed I’ll generate the daily trade list, build the P&L series, and present the full return & risk statistics.
