Told You So!
Brad DeLong gives some pointers to what one ought to read if one's interested in investing wisely, and his suggestions turn out to be rather similar to my own (albeit more detailed). He points out, just as I have, that if one wants to invest in stocks, the best way to do so is to simply go with an index fund, and to keep an eye out for the management fees charged, the lower the better.
I'm not going to pretend that this is evidence of my own unique financial expertise, as it isn't. Anyone who knows a thing or two about finance really ought to know these things, though if one considers the number of people who engaged in day trading, the popularity of technical analysis, and the continued existence of investment funds based on stock picking, an extremely large number of people out there haven't a clue about the subject.
