Dear 妹夫：
针对本次关于QQQ及TQQQ历史价格与图表数据的疑惑，现作出正式、客观的统一说明，厘清两者真实原始价值、拆股规模及行情图表的数据失真问题。
To resolve the confusion regarding the historical pricing and chart data of QQQ and TQQQ, here is a formal and objective explanation clarifying their true original value, split scales, and data distortion in conventional market charts.

一、核心原理说明｜Core Principle
市场行情软件预设复权走势图，会自动抹平历次拆股价格缺口，导致历史报价被人为修正，无法反映上市当日真实成交价。若要客观对比两只ETF的长线真实价值，必须还原所有拆股调整，以原始发行单位作为计算基准。
Default market charts apply automatic price adjustment to eliminate gaps caused by stock splits, which artificially revises historical prices and deviates from actual traded prices at launch. An objective long-term value comparison must be based on fully restored pre-split original share units.

二、QQQ 真实价值还原｜QQQ True Value Restoration
QQQ 于1999年3月10日上市，上市首日真实开盘价为51.13美元。该ETF自成立至今仅执行一次2:1正向拆股，无其他拆合股记录。
QQQ was listed on March 10, 1999, with an actual opening price of $51.13 on its launch day. It has only implemented one 2-for-1 forward split throughout its history, with no other split or reverse split records.
以昨日收市价710.72美元计算，现行股价为拆股后的交易价格。还原至原始上市单位，其对等价值为：710.72 × 2 = 1421.44美元。此数值为QQQ对比1999年原始股本的真实累计价值，复权图表的历史价格不具备对比参考性。
Based on the closing price of $710.72, the current price is post-split pricing. Restored to the original listing unit, the equivalent value is $710.72 × 2 = $1421.44. This represents the true cumulative value relative to QQQ’s 1999 original share capital. Adjusted chart prices are not valid for historical value comparison.

三、TQQQ 真实价值还原｜TQQQ True Value Restoration
TQQQ 于2010年2月11日上市，属于杠杆型ETF，与QQQ拆股机制完全独立、互不通用。该产品上市以来累计经历八次正向拆股，累计拆细倍数为384倍。
Listed on February 11, 2010, TQQQ is a leveraged ETF with a completely independent split mechanism from QQQ. It has undergone eight forward splits with a total split multiple of 384 times.
换算逻辑为：当前1股TQQQ，仅等同于2010年上市原始股本的1/384。因此384倍还原参数为TQQQ专属指标，仅适用于该杠杆ETF，绝不可套用于QQQ进行计算，否则会产生严重数据偏差。
In other words, one current TQQQ share equals only 1/384 of one original 2010 launch share. The 384x restoration factor is exclusive to TQQQ and must not be applied to QQQ, as it will cause severe computational deviation.

四、总结与专业结论｜Conclusion
1\. QQQ拆股次数极少，价值变动规律稳定，现价还原原始价值倍数为2倍；
1\. QQQ has minimal split records with stable value changes, requiring only a 2x multiplier for original value restoration.
2\. TQQQ因杠杆属性频繁拆股，股本持续稀释，存在384倍超大拆细倍数，与QQQ数据体系完全分离；
2\. Due to leveraged attributes, TQQQ has frequent splits and continuous share dilution with a 384x split multiple, forming a completely independent data system from QQQ.
3\. 所有预设复权行情图仅适用于粗略查看涨跌幅，不可用于原始价值对比、长线回测及价值研判，否则易出现根本性判断失误。
3\. Default adjusted charts are only for simple return reference and cannot be used for original value comparison, long-term backtesting, or value analysis, to avoid fundamental judgment errors.
