Unless the investment was into worthless paper from those companies, tied to pension funds and similar.
So evidence that internet was a bubble is wrong, it in fact shows that pensions did the right thing by putting money in the internet.
Now, if you had put your money in those stocks 12 months later, you would do okay (except for Sun). So, no, those pensions did not do the right thing by buying at the peak of a bubble. At least, not for people like me who don't like 15 years of negative returns.
