Stocks that are up 15 % in last month

Screening Filters

1. month_price_change_pct: { min: 15 }

   • Purpose: Select stocks whose price has increased by at least 15% over the last month.
   • Rationale:
     • The user asked for “stocks … that have increased by 15% in the last month.”
     • This filter directly implements that by requiring a minimum 15% price gain over the most recent 1‑month period.
     • Using a “min” of 15% ensures we include all stocks at or above that threshold, not just those exactly at 15%.

2. list_exchange: ['XNYS', 'XNAS', 'XASE']

   • Purpose: Limit results to stocks listed on major U.S. exchanges.
   • Rationale:
     • The user requested “stocks listed in the US stock market.”
     • XNYS = New York Stock Exchange, XNAS = Nasdaq, XASE = NYSE American (formerly AMEX).
     • These are the primary U.S. exchanges, so this filter aligns the universe of stocks with the user’s requirement.

Why Results Match:

• The performance condition (≥ 15% price increase over the last month) is matched by the month_price_change_pct filter.
• The location/exchange condition (listed in the U.S. stock market) is matched by restricting to XNYS, XNAS, and XASE, which are the main U.S. stock exchanges.

So the filters used directly correspond to both parts of the user’s request and are appropriate for finding the most relevant stocks.
