That makes no sense at all. What you're saying is it's possible to hire people who can see the future. Index tracking works because the market as a whole generally trends upwards if you wait long enough. This would be expected as the world generally gets richer and technology generally improves. The problem is you can't predict which exact company is going to do the improving. So just buy a very wide spread of companies and take the average. 80% of active managers fail to beat the market because they cannot see the future. The other 20% are lucky (today). If you want a lesson in the dangers of active management, look up Neil Woodford.
