Slowly moving towards more ETFs..currently in VTI $Vanguard Total Stock Market ETF (VTI.US)$ but possibly looking at QQQM too. Currently invested in MSFT $Microsoft (MSFT.US)$ , GOOGL $Alphabet-A (GOOGL.US)$ , AAPL $Apple (AAPL.US)$ , and TSLA $Tesla (TSLA.US)$ . Too much exposure to own any of these in addition even if less than 10%? Maybe selling two? Or just hold and not invest in QQQM.
