Reading press releases like this one makes me quite happy to not being an index investor:
SMITHS FALLS, ON, March 10, 2017 /CNW/ – Canopy Growth Corporation (TSX: WEED) (“Canopy Growth” or “the Company”) today announced that by being added to the S&P/TSX Composite Index, it has achieved another major “first” in the cannabis industry. Management expects this to drive liquidity and increase the percentage of institutions holding Canopy Growth positions. In short, more investors than ever will be buying and holding WEED.
It is pretty obvious that future outsized gains to be made in the marketplace are going to be in companies that are not in the major indexes.
