"It’s a mistake to seek funds that will consistently outperform.
While long winning streaks are associated with outperformance,
it’s rare for funds to repeatedly top their indexes, making them hard to identify upfront."
"Moreover, long-term winners often take a circuitous route to outperformance,
perhaps topping their indexes over a span of a year or two, then lagging, only to resume their winning ways."
