IDA uses a custom blended index strategy. We also look at all the major and common indexes. Our fiduciary financial advisers help clients understand the appropriate benchmark to compare performance against. Benchmarks and indexes are often misunderstood. For example, many people will ask about the markets when referring to the S&P 500, Dow Jones 30, or Nasdaq 100. While those indexes are a good representation of the US large cap markets, they are a poor representation of a total stock market and zero representation to the bond market.
