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. Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Cohort (LON:CHRT). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

Are Cohort Insiders Aligned With All Shareholders?

Insider interest in a company always sparks a bit of intrigue and many investors are on the lookout for companies where insiders are putting their money where their mouth is. This view is based on the possibility that stock purchases signal bullishness on behalf of the buyer. Of course, we can never be sure what insiders are thinking, we can only judge their actions.

Despite some Cohort insiders disposing of some shares, we note that there was UK￡77k more in buying interest among those who know the company best Although some people may hesitate due to the share sales, the fact that insiders bought more than they sold, is a positive thing to note. It is also worth noting that it was Independent Non-Executive director Peter Lynas who made the biggest single purchase, worth UK￡82k, paying UK￡5.45 per share.
