Aswath Damodaran, in part three of these investment philosophies videos, talks about activist growth investing, information trading, pure and near arbitrage and much more.

Investment Philosophies: Activist Growth Investing – Be your own change agent

In this session, we look at growth investing strategies where you not only invest in growth companies but also play a role in their growth. In particular, we focus on venture capital investing, by looking at the process by which a young, start-up negotiates with a venture capitalist and how the latter tries to profit from the investment. We also evaluate the failure risk that venture capitalists face, while investing in young companies, and the overall returns generated by venture capital investing over long time periods.

Investment Philosophies: Growth Investing – Against the tide of history?

In this session, we wrap up our discussion of growth investing by looking at why some investors may choose to be growth investors, even though it has historically not delivered the types of return that value investing has. In particular, we note that investors who are good at timing macro or market-wide shifts in interest rates and earnings can also generate high returns from growth investing. We also present evidence that activity (collecting and processing information, doing research) has a much bigger payoff with growth stocks than with value stocks, perhaps because markets make bigger mistakes with growth stocks and investors are far more likely to give up on intrinsic valuation.

Investment Philosophies: Information Trading – Trading on the news

In this session, we introduce information trading (as a philosophy) by first delineating how efficient markets should respond to new information, as opposed to slow learning or over reacting markets. We then lay out different ways in which investors can play the information game: by getting a whiff of forthcoming information announcements (from private sources, rumors or research) and trading on that basis, by trading on the information announcement itself on the assumption that the immediate market reaction is likely to be skewed or investing after the announcement on the presumption that markets learn slowly or over react.

Investment Philosophies: Information Trading – Following the insiders

In this session, we look at a strategy of following the insiders in a company, buying when they are buying and selling when they are, on the assumption that insiders know more about a company’s value than market participants. To evaluate whether this strategy works, we first look at whether insider trading is a good predictor of stock returns in subsequent time periods. While we do find that insider buying (selling) is followed by positive (negative) market returns, we also find that the signal is often wrong and that timely access to the insider trading information is critical. We also find insider trading is more predictive, if top executives are involved and at smaller companies. Finally, we conclude that we would generate far more lucrative payoffs if we had access to illegal insider trading information.

Investment Philosophies: Information Trading – Following the analysts

In this session, we look at equity research analysts and consider whether following their advice is a market-beating strategy. We begin by looking at earnings estimates from analysts and note that while they are better predictors of actual earnings than time series models (which use only past earnings), the improvement in accuracy is modest and primarily in short term forecasts. We also note that revisions made by analysts to earnings estimates often generate short-term price momentum in stocks, perhaps because analysts can get clients to trade on those revisions. Finally, we look at analyst recommendations, by first reporting on the bias in the process (with positive recommendations vastly outnumbering negative recommendations) and then looking at the price impact of these recommendations. We note that sell recommendations have larger, long-term price impact than buy recommendations and that some analysts have more impact than others, either because their recommendations are built around stronger narratives or because they have more institutional following. A strategy of investing based upon analyst recommendations is unlikely to yield high returns unless it is focused on smaller, less followed companies and more influential, unbiased analysts.

Investment Philosophies: Information Trading – Public Information – Earnings Reports

In this session, we begin our discussion of trading based upon public information by looking at earnings reports. Since markets react to the news in earnings reports, we begin by categorizing that news into good, neutral and bad, by comparing the actual earnings to the predicted earnings. Not only do we see a price change that is consistent with the nature and magnitude of the surprise (positive price changes on positive surprises) but we also see two other phenomena. The first is that prices start to drift in the direction of the surprise even before the earnings report is made public (suggesting that someone is trading illegally ahead of the report) and that they continue to drift in the same direction after the report comes out (suggesting a slow learning market). We also look at earnings reports that are delayed and find that they are more likely to contain bad news. Finally, we look at the speed of price reaction on the day of the report and find that prices adjust quickly to earnings surprises, suggesting that any investment strategy built around earnings surprises has to be built around speedy trading/execution.

Investment Philosophies: Information Trading – Public information, other than earnings

In this session, we turn our attention to public announcements other than earnings. We begin by looking at acquisition announcements, establishing that the winners in acquisitions are clearly target company stockholders and that many acquisitions don’t work in delivering value to acquiring company stockholders either at the time of the announcement or in the years after. We look at investment strategies built around acquisitions, with the most lucrative one being the identification of potential target companies ahead of the acquisition announcements. We also look at stock splits, where the evidence of a price reaction is mixed, and dividend announcements, where increases (decreases) in dividends are accompanied by stock price increases (decreases), though the price effect has decreased over time.

Investment Philosophies: Too Good to be true? Pure Arbitrage

In this session, we lay down the requirements for pure arbitrage: assets
