Another note about employing strategies like market-neutral or leveraged short ETFs is that you can use it as a placeholder/store-of-buying power. When the market corrects or if it ever crashes again, these holdings will hit their all-time highs, allowing you to sell for major gains to use to double down on ur holdings that are red but you still have conviction in the long-term.
Having a constant position in a market-neutral would be recommended with periodic reinvestment. Having a leveraged short ETF would only be recommended when the market is feeling top-ish or you need some sort of inversely correlated asset. So for instance, I always hold BTAL and add more shares, but I am in and out of SQQQ. I keep about 5% in the market-neutral and only 1% in the levered short. Right now I am in. It is at 52-week range lows and if the NASDAQ corrects this stands to benefit and is easier than firing off a put option/spread and worrying about timing.
