Error message

What it means

Solutions

1. Search the symbol via search_securities to see Yahoo's canonical form and use that exact symbol
2. Confirm the ticker still exists on finance.yahoo.com — delisted symbols return empty results
3. Check normalize_symbol behavior for the given mic — pass the correct exchange_operating_mic so suffixes are applied properly
4. Rescue this error and mark the security as 'info unavailable' instead of failing the whole sync

Example fix

// before
info = provider.fetch_security_info(symbol: symbol, exchange_operating_mic: mic)

// after
begin
  info = provider.fetch_security_info(symbol: symbol, exchange_operating_mic: mic)
rescue Provider::YahooFinance::Error => e
  raise unless e.message.include?("No security info found")
  matches = provider.search_securities(symbol)
  canonical = matches.first
  info = canonical ? provider.fetch_security_info(symbol: canonical.symbol, exchange_operating_mic: canonical.exchange_operating_mic) : nil
end

begin
  provider.fetch_security_info(symbol:, exchange_operating_mic:)
rescue Provider::YahooFinance::Error => e
  raise unless e.message.include?("No security info found")
  match = provider.search_securities(symbol).first
  match ? provider.fetch_security_info(symbol: match.symbol, exchange_operating_mic: match.exchange_operating_mic) : nil
end

When it happens

Trigger: Requesting info for an unknown, delisted, or renamed symbol; a symbol valid on one exchange but normalized to a Yahoo form that has no quoteSummary (suffix/prefix mismatches like 'ASML.AS' vs 'ASML'); symbols for asset types the endpoint doesn't summarize.

Common situations: Stored security symbols going stale after delisting/rename; symbols imported from another provider (Trading 212, Twelve Data) not matching Yahoo's format; OTC or thinly-traded tickers lacking quoteSummary modules.
