The market has a long ways to drop yet. Airlines are just starting to announce major cuts to their flights (e. g. Lufthansa just announced a 25% reduction in flights), the Olympics are possibly being cancelled, Trump is floating border closures with Mexico, travel to Europe may be severely hampered, conferences are being cancelled, the NYSE is talking about having to close their trading floor, pro sports events aren't allowing fans to attend and so forth. While dollar cost averaging is generally a good idea, sometimes, it's blatantly obvious that larger falls are still to come imminently and so it's not a bad idea to modify your buying behaviour for a short time, but have a clear plan for how you're going to deal with this situation. Maybe instead of buying monthly, you go to quarterly or semi-annually. The plan isn't to catch the bottom as you're highly unlikely to do so. The plan is to avoid a lot of the blatantly obvious sharp downward movement we're going to experience for the next few months as things shutdown/reorganize for a new normal.
