Generally, stock funds launch following long runs up in stocks, when the appetite for stock investing is high. In particular, these launches tend to occur in the hottest of the already hot market. That's why so many Japanese, Asian, and emerging market funds launched in the early 1990s (to kick off the U.S. and other fully emerged stock market decade with emerging markets lagging), small cap funds a few years after that (right before larger cap led the market), larger cap growth and tech funds in the late 1990s (before the 2000 crash), "dividend" and yield-focused funds around the mid 2000s (before high dividend banks collapsed), emerging market funds yet again in recent years, and commodity funds.
