Close to 45% of my lithium investment is in Galaxy because it is my favorite junior producer. I have also invested about 40% in Altura, who will produce in about 6 months. I sold Orocobr after making about 30%, but still like it and should have kept it. I consider these 3 stocks to be my favourite junior producers, but there are few others in the same category (Pilbara, Neometals, etc.). I prefer not invest in the bigger companies (SQM, ABL, FMC and Chinese) or in the LIT ETF. I see more upside potential in the junior producers and I feel that they are not risky even though they are volatile. Finally, I do have about 15% invested in small junior explorers that I feel have a realistic chance of producing in 2-3 years. I currently hold Lithium America and Nemaska, and I will certainly buy Advantage Lithium when it dips. I am extra careful with these companies because I see more risk and volatility, but I also see tremendous upside. My plan is to hold 4-6 lithium companies at all times and to rebalance my portfolio as needed..
I hope this helps, good luck with your investment decisions and please spread the word to your friends that the lithium boom is here to stay for many years!
