What is good to tread in spy500

Screening Filters

1. monthly_average_dollar_volume ≥ $10,000,000

   • Purpose: Make sure the ETFs are highly liquid and easy to trade in size.
   • Rationale: When you ask “what is good to trade in SPY (S&P 500 ETF)?”, liquidity is critical—especially if you’re trading actively or intraday. A high dollar volume typically means:
     • Tight bid–ask spreads (lower trading cost)
     • Easier entries and exits without moving the market
     • More reliable price action for technical trading

2. themes = Large Cap Blend Equities

   • Purpose: Focus on funds that have a similar risk/return profile to SPY.
   • Rationale: SPY tracks the S&P 500, which is a U.S. large‑cap blend index (mix of growth and value). Restricting to “Large Cap Blend Equities” keeps the results in the same asset class and style as SPY, so any alternatives behave broadly like SPY rather than small-cap, sector, or international funds.

3. names = [SPDR S&P 500 ETF Trust (SPY), iShares Core S&P 500 ETF (IVV), Vanguard S&P 500 ETF (VOO), Schwab U.S. Large-Cap ETF (SCHX), SPDR Portfolio S&P 500 ETF (SPLG), Invesco S&P 500 Equal Weight ETF (RSP), ProShares S&P 500 ETF (XLG), S&P 500]

   • Purpose: Explicitly target the main S&P 500 and S&P‑500‑like ETFs.
   • Rationale: You asked specifically about trading SPY / S&P 500. This name list:
     • Includes SPY itself
     • Adds the most common alternative S&P 500 trackers (IVV, VOO, SPLG)
     • Includes very similar large‑cap U.S. broad‑market funds (SCHX, XLG, RSP) that traders often use as SPY substitutes
       This ensures the screen surfaces exactly the “SPY-type” products you’d realistically consider trading.

4. expense_ratio ≤ 0.10%

   • Purpose: Limit results to very low-cost ETFs.
   • Rationale: Even if you’re trading rather than long‑term investing, high expense ratios eat into returns over time. Capping at 0.10%:
     • Eliminates niche or leveraged products with high ongoing fees
     • Leaves you with core, efficient index ETFs that are typically best vehicles for broad S&P 500 exposure

5. inception_date ≤ 2015-01-01

   • Purpose: Require a long, established track record.
   • Rationale: Funds that launched before 2015 have:
     • A full market cycle (or more) of history for backtesting and analysis
     • Lower risk of being closed/merged away
     • Proven ability to track their benchmark through different conditions
       For someone trading SPY-like ETFs, this helps ensure you’re only looking at well‑proven, stable products.
