For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it currently lacks a track record of revenue and profit. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. A loss-making company is yet to prove itself with profit, and eventually the inflow of external capital may dry up.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Sterling Infrastructure (NASDAQ:STRL). While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.
