I am opportunistic trader that concentrates at buying shares in solid but underappreciated companies. When the time seems right, I'll happily invest in indices, commodities or cryptos as well. Most of my positions are very small and spread both geographically and over different sectors. However, a majority of my investment is usually in just a few positions that I have high confidence in. Usually, all of my positions are below 10% of the portfolio, except in the cases when some stock that I consider especially valuable goes down significantly for a while and I buy the dip in expectation that the value will go up significantly within weeks or months.
