The provided text contains no relevant news about the Invesco QQQ Trust. The only mention of the symbol 'QQQ' refers to a completely different company, Questcorp Mining Inc., which trades under the stock symbol 'QQQ' on the Canadian Securities Exchange. This is a case of symbol confusion, as the mining company's news about a gold discovery in Mexico has no connection to the Invesco QQQ Trust ETF, which tracks the Nasdaq-100 index.
