Etsy Shares Plunge 0.70% as $260M Volume Closes 430th in Market Activity
On September 25, 2025, EtsyETSY-- (ETSY) closed down 0.70%, with a trading volume of $260 million, ranking it 430th in market activity for the day. The decline reflects mixed investor sentiment amid ongoing debates over the platform’s long-term growth potential and operational efficiency in a competitive e-commerce landscape.
To accurately execute a back-test, several parameters must be clarified. The universe of "top 500 stocks by daily trading volume" requires specification—whether it includes all U.S. common stocks, a specific index (e.g., S&P 1500, Russell 3000), or another list. Trade timing and pricing conventions also need definition: positions could open at today’s close and exit at tomorrow’s close (a standard 1-day holding period) or utilize next-day open prices for entry/exit. Equal-weight allocation across the 500 names each day is another consideration.
For portfolio back-testing, the current tools support single-ticker or event-driven analysis but lack multi-asset engines for daily-rebalanced cross-sectional portfolios. Two approaches are viable: a custom Python script to fetch daily constituents, calculate equal-weighted returns, and summarize results, or an ETF approximation using a tradable vehicle tracking high-volume stocks. Confirmation on universe scope, timing preferences, and methodology choice (custom analysis or ETF proxy) is required to proceed with the back-testing workflow.
