The average price appreciation when a company is added to the TMX typically varies, but studies suggest that stocks can see a short-term boost due to increased demand from index funds and passive investors.
Immediate Impact: Research indicates that stock prices can rise by 3-5% in the weeks following the announcement of inclusion. This is largely driven by index funds buying the stock to match the index, a phenomenon known as the “index inclusion effect.”
Post-Inclusion Behavior: After the initial spike, the price often stabilizes.
Factors Influencing Appreciation:
Liquidity: More liquid stocks tend to see smaller percentage increases because their shares are easier to buy without driving up the price.
Market Sentiment: A bull market or optimism about the sector can amplify gains.
Passive Investing: The growing influence of ETFs and index funds has heightened the impact of index inclusion on stock prices.
