Novice writers and writing instructors in academic and professional settings often pine for guides that will deliver definitive rules which offer certitude. Steven Pinker's The Sense of Style: The Thinking Person's Guide to Writing in the 21st Century does soto a large extent. That The Sense of Style cannot find rules in reason for everything is perhaps its most importantthough unintendedmessage. For as it demonstrates, style remains haunted by the residues of taste and authority.
We study the trading behavior of retail investors in the market of leveraged bank-issued retail derivatives designed to trade excessively, speculate and gamble on ongoing trends and market movements. We analyze whether retail investors have private information and benefit disproportionately or whether they gamble. We answer this question along three dimensions: (i) profitability, (ii) news trading, and (iii) sensitivity to implicit trading costs. We distinguish derivatives by the type of underlying (index vs. individual stocks). We find that raw returns are negative for derivatives with stock as underlying, and only partially positive for those with index as underlying. Nevertheless, riskadjusted returns show a poor performance with sharpe ratios below one. We show that retail investors are attracted by news, but do not have private information prior to news events. Finally, we categorize investors according to their sensitivity to implicit trading costs. We find that non-sensitive investors perform worse than sensitive investors. JEL Classification: G10, G14.
