According to Evan (@StockMKTNewz), the NASDAQ 100 ETF ($QQQ) has exhibited significant annual volatility since 1999, with notable surges in years like 1999 (+79%) and 2009 (+54.7%), and sharp declines during 2000-2002 and 2008. For cryptocurrency traders, these cycles highlight the strong correlation between tech equities and crypto market sentiment, especially during risk-on or risk-off periods. Understanding these historical equity trends can help crypto investors anticipate potential liquidity shifts and manage portfolio risk as tech stocks often lead broader risk asset moves.
