ProShares UltraPro QQQ (NasdaqGS: TQQQ)
YTD: 120.2%
Comment: TQQQ is the triple-leveraged cousin of the popular PowerShares QQQ (NasdaqGS: QQQ), the Nasdaq 100 tracking ETF. With the Nasdaq Composite hovering around 4,000, its highest level in 13 years, there is ample bubble talk. That would of course be damaging to TQQQ, but noteworthy is the fact that QQQ’s valuations are not yet indicative of a bubble.
