Ignore Peter Schiff's constant doomsday predictions - we will eventually see another big recession and bear market, but he's been predicting that it's going to happen any day now for the last decade. He desperately wants to sell off his massive precious metals stake he's been accumulating ever since the last recession.
Ignore the MSM fantasies of a Trump impeachment and jail time for everyone in the Trump family - you can only kick a POTUS out of office and jail his entire family when they've committed actual crimes, and even then only when their rights were not violated during the investigations / trials of any such crimes. And even if all of this happened, the effects on the market would not likely be as great as many might think.
If you're a longterm investor investing for retirement decades away, continue to add $100-400 a week (or month) to your diversified retirement accounts, knowing that you're buying more shares of your investments when the markets sell off and those investments get cheaper.
If you're a more tactical trader / investor, view dips/corrections/bear markets as buying opportunities, and rallies as opportunities to perhaps take some profits. Add $ to your accounts each payday. Keep some cash onhand, and consider carefully hedging if you're so inclined. Be more "bottom-up" - you cannot control the market, but you can control which investments you choose.
IF we were to see the Dow at 11-12k in a year, consider how cheap good stocks would be at that level. Since we don't know for sure if that will happen (probably won't), many stocks are pretty cheap at 22-23k, and would be even more attractive at 17-18k. Much of the volatility in the markets these days is due to the automated HFT funds basically overreacting to whatever is occurring on a day to day basis.
Interest rates are higher and rising from where they were for much of the last decade, but underlying fundamentals are quite solid - which of course is why rates are rising. I tend to buy more as investments become cheaper, and take some profits (not necessarily all) when they tend to become overpriced.
High beta investments such as the FAANGs, Tesla, etc are going to usually get hit the hardest in bad times. Having some lower beta high quality stocks in your portfolio is probably a good idea. Bonds on average tend to have 20-25% of the beta that stocks do, but they will also decline in a rising rate environment.
