Particularly as a mountain dweller, I would need to generalize this beyond cycling.Much like investing, cycling does not depend on the conditions, just on the proper mindset and preparation.
Like outdoor exercise, investing is possible in "all weather conditions". The "weather" (i.e., economic/social conditions) will often dictate the best overall approach. For example, in stormy weather as we are facing today, we generally want to be holding on tightly and accumulating more shares in tranches, going with top-quality investments like Tesla (in my opinion). In gorgeous weather, which we had for much of the last 12 months, we want to be looking for opportunities to increase cash reserves in preparation for storms ahead. In all weather, it's important to remain calm and humble.
