5 years of stock trading: What I’ve learned

Reflecting on my past 5 years of small-time investments.

I’ve obviously been very, very lucky. Of the 19 stocks I’ve bought for the past 5 years, 13 was profitable. The top 6 most profitable stocks returned a combined profit of $22 236, while the top 6 biggest losses only cost me a total of $843. The one biggest investment (Paradox Interactive) made up 80% of my total profits.

Biggest mistake

Trying to “diversify” my portfolio by buying several big, traditional Norwegian stocks like Norsk Hydro, AF Gruppen and Orkla. A diversified portfolio strives to reduce loss while giving a decent return. Just buying a random bunch of big “safe” companies is not good diversification, nor can any company be considered “safe”. To do that properly, I should have followed a strategy, like Ray Dalio’s All Weather portfolio. As it turned out, my biggest loss over the past 5 years is Norsk Hydro, meant to be my most boring and safest bet, ending up at -20% even after buying several times at lower valuations.

Best decision

Changing my strategy from the misguided “diversification”, and cutting my portfolio to only 1-3 stocks. I didn’t know anything about those big companies I bought, barely what they sold. I had no idea how different news affected them, and that made me unable to react to anything. When focusing on just a few select companies I actually thought were interesting and knew a little about, I was in a much better position to make decisions.

On Paradox Interactive

The above decision made me trust my instinct and going almost all-in on Paradox Interactive after my initial research on them, and then keep buying it even as the valuation grew.

I first became aware of Paradox after playing some of their games, and noticing their clever expansion pack strategy that could make hardcore players spend between 100-200$ on each game. They had a good selection of titles, and I enjoyed several of them myself. Paradox bought some interesting companies, and was also a publisher of games, not just a producer. They were for example the chosen partner for the highly successful Cities: Skylines.

When I saw they were valued at roughly the same price as Funcom, the norwegian game studio behind the hyped Conan Exiles, I sensed an opportunity and started to dig a little deeper.

I got lucky on this bet, and it ended up making 80% of my total profit.
