You're overthinking it, there's risk on holding due to the structure of the ETF but the Dow was wildly overpriced at 24k. The economy is about to crater. Even if the virus disappeared tomorrow it takes time to hire and train and for consumers to rebuild demand. This thing will be at 100 in a matter of months.You have to buy and sell to limit exposure since it tracks based on daily percentage and not price. Feb 21 it was at $35.80 and the DJIA was at 29k. It went to $90 when the DJIA dropped to 18k, but on the ascent, since it is an inverse fund it was dropping larger percentages because smaller DJIA gains were now larger percentages. It closed at $35.20 yesterday. If you had held since Feb 21 you would have lost money. What you can do is partial sells as the price increases to limit exposure to the downside, however that is too time consuming for non day traders. I prefer to just buy for a day after the market jumps big. Especially during these poor market conditions.
