Passive investing in index funds can generate returns that roughly match the overall market. But if you pick the right individual stocks, you could make more than that. To wit, the K2fly Limited (ASX:K2F) share price is 87% higher than it was a year ago, much better than the market return of around 20% (not including dividends) in the same period. If it can keep that out-performance up over the long term, investors will do very well! And shareholders have also done well over the long term, with an increase of 65% in the last three years.

Because K2fly made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. When a company doesn't make profits, we'd generally expect to see good revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

In the last year K2fly saw its revenue grow by 50%. That's well above most other pre-profit companies. The solid 87% share price gain goes down pretty well, but it's not necessarily as good as you might expect given the top notch revenue growth. So quite frankly it could be a good time to investigate K2fly in some detail. Human beings have trouble conceptualizing (and valuing) exponential growth. Is that what we're seeing here?

A Different Perspective

It's nice to see that K2fly shareholders have gained 87% (in total) over the last year. That's better than the annualized TSR of 18% over the last three years.

While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
