I’m very happy with my portfolio. The potential is good enough that I believe I will come out ahead even if this one failed. But I am confident here and feel pretty good in my investment. This is not my only stock though, as it is for some. I invest in high volatility, high potential stocks, in some concentrated areas to cumulatively build expertise and make my dd somewhat cumulative in terms of the science and technologies.
But it is a good idea to have a few eggs in that basket, in my experience. It allows you also to use tax strategies as well to build the cumulative portfolio, if it comes to that... or just to rebalance the portfolio when you have some big gains and lower the transaction costs of rebalancing.
Good luck to everyone!
