RT Journal Article SR Electronic T1 Market Reactions to Changes in the S&P/TSX SmallCap Index JF The Journal of Index Investing FD Institutional Investor Journals SP 57 OP 64 DO 10.3905/jii.2014.5.2.057 VO 5 IS 2 A1 Ernest N. Biktimirov A1 Boya Li YR 2014 UL https://pm-research.com/content/5/2/57.abstract AB Stocks added to major indexes generally experience positive abnormal returns. However, researchers disagree on whether these abnormal returns are permanent or temporary, and offer competing explanations. We examine stock price and trading volume reactions to changes in the Canadian S&P/TSX SmallCap Index. Our primary finding is that significant changes in prices and trading volume occur for stocks added to or deleted from the S&P/TSX SmallCap Index. The effect depends on whether a stock is a pure addition or deletion as opposed to being shifted between S&P/TSX indexes.TOPICS: Mutual funds/passive investing/indexing, fundamental equity analysis, developed
