Henry Blodget

But relationships that seem causal and permanent in one market era often vanish in the next, taking many “superior investment strategies” down with them. Today’s markets are also annoyingly efficient. The more studies that demonstrate that socially responsible stocks do better than regular stocks, the more investors will rush to buy them (and not just for “the greater good”).

Henry Blodget

The first problem with labeling a particular style of investing “socially responsible” is that it suggests that other kinds of investing are not. So it’s no wonder many people find the concept silly or offensive.

Do hedge funds improve management of the companies they invest in? A new study by Harvard Business School professor Robin Greenwood and coauthor Michael Schor argues that, in fact, hedge funds create shareholder value through anticipation of change, not necessarily delivering it.

It is the creation of economists, who try to understand the market as a whole, rather than business analysts, who look for what makes each investment opportunity unique.

The volatility is equated with “risk”, measuring how much … [ Read more ]
