2 Research Question Do retail investors display a negativity bias in attention allocation with respect to stock returns? Negativity Bias in Attention Allocation 1 / 28
3 Preview of the Results We use direct measures of attention using search volume from Google. We relate these measures with other proxies for attention. We find that retail investors display a negativity bias with respect to extreme stock returns at the U.S., state, and company level. By redistributing returns, we rule out the bias is due because negative and positive returns are not symmetric. Negativity Bias in Attention Allocation 2 / 28
4 Motivation Hirshleifer et al. (2004) show individuals are net buyers after negative and positive earning surprises. Net purchases are greater after extreme negative earnings surprises than after extreme favorable ones. Barber and Odean (2008) show individuals are net buyers of attention grabbing stocks. Buy-sell imbalances are greater after negative return days than after positive return days. Negativity Bias in Attention Allocation 3 / 28
5 Literature Review Negativity bias in psychology: Pratto and John (1991) find that bad traits attract more attention in an automatic and non-intentional fashion than good traits; Baumeister et al. (2001) argue negative events will produce larger and more intense consequences than positive events. Use of search volume from Google: Varian and Choi (2009) show that search volume can predict home sales, automotive sales, and tourism; Da et al. (2009) use searches on tickers to proxy for attention in individual stocks and show increases in search volume lead to contemporaneous price increases and future return reversals.

6 Measuring Attention: Search Volume Internet users commonly use a search engine to gather information. If you search for a term, you have to be paying attention to it! Google tracks the amount (and geographical origin) of searches for most common terms since Negativity Bias in Attention Allocation 5 / 28
7 Measuring Attention: Search Volume Search Volume Index (SVI) from Google, SVIregion,t term Searchesregion,t term = Total Searches t Constant diet twitter 0.8 Search Volume Index Year Negativity Bias in Attention Allocation 6 / 28
8 Measuring Attention: Proxies We use three aggregate measures of attention: All Retail Investors Attention (AllInv) measures general interest in the stock market and price movements; New Investors Attention (NewInv) relates to people searching information to open a brokerage account; Old Investors Attention (OldInv) concerns to retail investors who already own a brokerage account and use Google to access it. We also use a measure of attention for specific stocks. Negativity Bias in Attention Allocation 7 / 28

Start with a small set of terms. Obtain related searches recommended by Google. Drop irrelevant terms. Iterate one last time with the remaining terms. Negativity Bias in Attention Allocation 8 / 28

Abnormal attention, ( ) NewInv r,t ANewInv r,t = log q=1 NewInv. r,t q r represents a geographical region, which can be the U.S. or a state. We use eight weeks to compute the base level of attention; our main results are robust to different window lengths. Negativity Bias in Attention Allocation 9 / 28

25 Robustness Checks: Distribution of Returns Redistribute negative returns to replicate the distribution of positive returns. For each week and portfolio (or stock): If the return is positive, keep it without modification. If the return is negative: (a) get the time-series returns for the past 5 years associated with that portfolio (or stock); (b) split the previous time-series into positive and negate returns; (c) find the percentile rank of the current (negative) return within the group of negative returns; (d) find a (positive) return, within the group of positive returns, with percentile rank closest to the one in (c); (e) replace the current (negative) return with the negative of the positive return from (d).

28 Conclusion We find that individual investors display a negativity bias in attention allocation with respect to stock returns. At the U.S., state, and company level, lagged negative extreme returns are stronger predictors of retail investors attention than positive extreme returns. By redistributing returns, we rule out that negative returns are stronger simply because negative and positive returns are not symmetric events to stockholders.
