The "high tech, high growth" fund wasn't?
When I worked for a stock market data processing company, we noticed that the total amount of periodic buys that fit a specific pattern matched some of the retirement funds exactly. i.e. we knew what the fund bought before anyone except their management team. They had a fixed formula of taking their nearly billion dollars of new funds each week and investing it in what made the most sense according to their rules and then spreading out what ever was left using some other system that might have involved a dart board or dice. We could watch the option buys where others had spotted this and were gambling on the major buys but we didn't see much evidence of the secondary buys but knowing them would have been very profitable. If a small group saw this in the data more than two decades ago, who is playing the system now? Oddly enough, IBM seemed to be the catchall stock when there wasn't anything making news.
