SPYGAState Street SPDR Portfolio S&P 500 Growth ETF

In short

IWO No data

SPYG The growth half of the S&P 500 for 0.04% a year, running since 2000. No exotic screen, no reinvention: just the index's fastest-growing names, in the cheapest wrapper tracking that index.

Stated mandate

IWO No data

SPYG The fund seeks to track, before fees and expenses, the total return of the S&P 500 Growth Index. It provides exposure to S&P 500 companies selected for strong growth characteristics.

Why people hold it

IWO No data

  • SPYG Costs 0.04% a year, well under the typical fee in the US growth-ETF group.
  • The cheapest way to buy the S&P 500 Growth Index: VOOG follows the same benchmark at 0.07%.
  • Has tracked its index tightly, one of the strongest implementations among growth funds we grade.
  • Trading since 2000, now a multi-billion-dollar fund that changes hands actively, so spreads stay thin. Pays quarterly.

Worth knowing

IWO No data

  • SPYG About 150 stocks, not 500. You get the growth slice, which means heavier single-name and sector concentration than the full index.
  • The index screens on growth and momentum, so rebalances lean into names that have already run and the ride is bumpier than the broad market.
  • Large-cap US only. No small caps, no international, no bonds.
