We’re in a bear market IMO and heading to recession, caused by the actions of central banks and governments after 2008 which inflated a massive asset bubble. IMO most US stocks will be on a volatile but downward trajectory for the next year at least, till inflation is under control or something breaks so badly that the Fed has to stop raising rates. Many other markets and global trackers follow the US. The answer in short term moves is often that nobody really knows - the financial press will make up post-hoc reasons for every move, but this is an irrational market whiplashing from optimism to pessimism.
Good news for you if starting off investing is you don’t have to care if your current investments are down this year as long as they are large stable companies or indexes, if you’re investing for the next few decades this will be a blip in that journey, if you can stay the course and invest in a mix of assets.
Try not to look every day, or if you do, try not to care, it’s important not to let emotions or a volatile market cloud decisions.
