Who are the members of the QQ family? one ️⃣ QQQ (old flagship, rate 0.18%): an absolute giant in the top 100 of the Nasdaq. I just completed the underlying transformation from UIT to modern open-end ETF at the end of last year and reduced the fees. The advantage is that liquidity is terrifying, with almost zero intraday spreads, making it the ultimate battlefield for short-term traders and option players. two ️⃣ QQQM (mini long line version, rate 0.15%): constituent stocks are 100% the same as QQ, but the management fee is 0.03% cheaper every year. Low unit price and minimal wear and tear. If you are a staunch "Buy and Hold" advocate and a loyal supporter, choose it directly, and every penny saved will be pure profit for the future. three ️⃣ QQQJ (Next Generation Mid Cap, Rate 0.15%): Anchors the 101st to 200th companies in the Nasdaq market capitalization (reserve for giants). There are no Nvidia or Apple here, but it is filled with explosive mid cap dark horses, and the industry distribution is more balanced, suitable for investors who like to explore future technology stars. four ️⃣ QQQS (Future Generation Small Cap, rate 0.20%): Select 200 small cap stocks with core hard core technology patents, with a high proportion of biotechnology and cutting-edge hard technology. The risk is high and the volatility is high, but the imagination space for explosive force and acquisition is enormous, making it suitable for radical factions as a satellite warehouse configuration. five ️⃣ QQQI (high dividend wild cousin, rate 0.68%): It is not an official product of Jingshun, but it has perfectly taken advantage of the popularity. The underlying buy and take refers to 100, with a covered call option strategy overlaid on top to "collect rent". Monthly payment with an annualized dividend of up to 13%+. The disadvantage is that a bull market will cap and underperform the main stocks. Suitable for investors who are extremely eager for cash flow and in the period of wealth harvest (retirement/interest earning).
